Use 150-grit sandpaper or a 220-grit mesh screen to sand drywall joint compound. That is what USG, the maker of Sheetrock compound, specifies: when you dry-sand, use nothing coarser than 150-grit paper or 220-grit abrasive mesh cloth. Save 220-grit paper or a fine sponge for a light pass after primer, and keep coarser grits like 100 or 120 for hard ridges in setting-type compound, if you use them at all.

Below is the grit for every stage, the difference between a sanding sponge, a pole sander and a power drywall sander, how to tell when the wall is sanded enough, and the times you shouldn’t sand at all.

Drywall Sandpaper Grit Chart

Not sanding drywall? The sandpaper grit chart and grit finder gives the sequence for wood, metal, car paint, plastics and more.

What Grit to Sand Drywall at Each Stage

Between Coats of Joint Compound

You don’t need sandpaper between most coats. USG’s instructions say to let each coat dry and “smooth lightly as required”, which usually means scraping off ridges and lumps with your taping knife before the next coat. If a coat dried with obvious tool marks, a quick pass with 150 grit keeps them from showing through the next one.

After the Final Coat of Mud

This is where most of the sanding happens. Go over the joints with 150-grit paper on a hand sander, or a 220-grit screen on a pole sander, feathering 6 to 8 inches beyond the edges of each joint. Sand only the compound and keep off the bare drywall paper as much as you can. If a joint still has a hard ridge, scrape it rather than reaching for coarser paper.

After Primer, Before Paint

Primer raises the paper fibers and shows every flaw. Once it’s dry, a very light pass with 220-grit paper or a fine sanding sponge knocks off the fuzz and specks. Don’t try to level anything at this stage: if a joint still shows, add a skim coat of compound, sand it and prime again.

Patches and Spackle

USG’s own patch instructions suggest a wet sponge to avoid dust and scuffing, or dry-sanding with 150-grit paper or 220-grit mesh. Spackle is soft, so press lightly or you will dish it out below the wall. My step-by-step is in how to sand a drywall patch.

Ceilings

Same grits as walls, 150 paper or a 220 screen, on a pole sander or a long-reach drywall sander, with even lighter pressure: gravity works against you and it’s easy to over-sand. Hold a bright light at a low angle so you can see what you are doing, and wear eye protection.

Setting-Type Compound

Setting-type (“hot”) compound dries much harder than ready-mixed mud. Many finishers use it only for the first coat and top it with an all-purpose or lightweight compound that sands easily. If you do have to sand a setting-type coat, some pros start at 100 or 120 to cut the ridges, then finish at 150. Test on a hidden spot first: hard compound next to soft paper is exactly where coarse grits gouge.

Sanding Sponge vs Pole Sander vs Drywall Sander

The grit stays the same whichever tool you use. What changes is how much wall you can cover, how flat the result is and how much dust you make.

Sanding Sponge

A sponge flexes into corners and around boxes where a flat pad can’t go, and you can rinse and reuse it. Used damp, it smooths compound with almost no airborne dust, which is why USG suggests a wet sponge for patches. The trade-off is flatness: a soft sponge follows small dips instead of bridging them, so it is a detail tool, not the way to do a whole wall.

Hand Sander and Pole Sander

Both hold a flat 4-1/4 x 11-1/4 inch sheet of paper or screen. The flat pad bridges low spots and levels the joint, which is what you want on long seams. A pole sander is the same pad on a swivel head and a long handle: it reaches ceilings and the tops of walls without a ladder, and it keeps the dust further from your face. Mesh screens suit poles best because they don’t tear on the swivel head and you can flip them.

Power Drywall Sander

A power drywall sander spins a large disc on a long boom and pulls the dust into a vacuum. For a single patch it is overkill. For a basement or an addition it does the main sanding far faster and with much less mess, and the dust control is worth it in a house you live in. The grit rule doesn’t change: use the finest disc that levels the joint, usually 150 or finer on all-purpose compound. I compare the DEWALT 20V MAX cordless, the Bosch GTR55-85 and the Festool Planex in my best sanders for walls and drywall. For a small job, a regular 1/4-sheet sander also works: see sheet sander vs random orbital sander.

My Picks for Each Stage

Gator Drywall Sanding Sheets, 150 Grit

Best for the Main Sanding

150 grit is the grit USG names for dry-sanding its compound, and these sheets are made for it: silicon carbide grain that Gator says leaves a smoother finish on drywall, a resin coating that resists heat and humidity, and a hook-and-loop backing for quick changes on a hand sander. Gator rates 120 and 150 for moderate sanding and blending of compound.

Check price on Amazon

• ✅ The grit USG recommends
• ✅ Silicon carbide cuts fast on mud
• ✅ Hook-and-loop for quick changes
• ❌ Six sheets: buy two packs for a whole room

Gator Drywall Sanding Screens, 220 Grit

Best for a Pole Sander

USG lists 220-grit mesh as the alternative to 150 paper, and this pack gives you 25 screens precut and notched to fit most drywall pole sanders. The open mesh lets dust fall through instead of clogging, it doesn’t tear like paper on a swivel head, and both sides are abrasive, so you flip it when the first side wears.

Check price on Amazon

• ✅ USG’s mesh equivalent of 150 paper
• ✅ Precut for pole sanders
• ✅ Two usable sides
• ❌ Cuts harder than 220 paper: not for the pass after primer

3M Drywall Sanding Sponge, Fine/Medium

Best for Corners and Patches

A dual-grit sponge: the medium side removes compound, the fine side smooths it, so one block covers a whole patch. The foam flexes to sand flat or contoured surfaces, which makes it the easiest tool for inside corners and around outlets, and you can rinse and reuse it. Used damp, it keeps dust down in a lived-in room.

Check price on Amazon

• ✅ Two grits in one block
• ✅ Flexes into corners and contours
• ✅ Rinse and reuse
• ❌ Small block: slow on whole walls

3M Sanding Sponge Block, Fine, Extra Large

Best for the Pass After Primer

After primer you want a gentle, even touch, and a fine-grit sponge gives exactly that. This 3M block is extra large at 2-7/8 x 8 in, so it bridges small dips instead of following them, and it works wet or dry on drywall, paint and wood. Keep one for the final check before paint.

Check price on Amazon

• ✅ Large flat face for an even finish
• ✅ Wet or dry, reusable
• ❌ Not for leveling bare mud

Putting the Grits in Order

1. Scrape before you sand. Knocking ridges off with a taping knife is what lets 150 grit do the job, so you never need coarser paper.
2. 150 paper or a 220 screen on the mud. Light pressure on the joints and screw spots, feathering the edges into the wall.
3. 220 paper or a fine sponge after primer, one light pass, then paint.

The full process, from prep and corners to ceilings and dust control, is in my guide on how to sand drywall. To keep dust off everything else, a shop vac with a fine filter on the sander’s port helps a lot: see my picks for the best shop vac for dust collection.

How to Tell When Drywall Is Sanded Enough

• The raking light shows no ridges or tool marks. Move the light along each joint; shadows mean high spots.
• Your hand slides over the joint without catching. Run a flat palm across it, not your fingertips.
• The edges of the compound disappear into the paper. You shouldn’t feel or see a step where the mud ends.
• There is no fuzzy paper. Fuzz means you went through the compound: stop, prime and skim that spot.

Primer is the final check. It shows every flaw sanding missed, so look again in raking light after the first coat of primer, before the paint.

Should You Use 400 or 600 Grit Before Painting Drywall?

No. Those are grits for sanding between coats of varnish or wet sanding car paint, not for drywall. Paint needs a little texture to grip, and USG says surfaces must be dry, dust-free and “not glossy” before decorating: very fine paper polishes the compound instead. Stop at 150 on the mud and 220 for the light pass after primer.

When Not to Sand Drywall

• When the mud is still damp. It gums up the paper and tears out of the joint.
• On the bare drywall paper. Sanding the paper face raises fuzz that shows through paint.
• When a wet sponge will do. For small touch-ups in a furnished room, a damp sponge smooths compound with almost no dust.
• In older homes, before testing. Joint compound in homes built before about 1980 may contain asbestos, and old paint may contain lead. Have it tested before you sand.

To remove stain from wood, strip off the clear topcoat first, then sand the stained wood back to bare fibers, and bleach whatever color is left. Stain isn’t a coating that sits on top like paint: it soaks into the wood. That’s why a chemical stripper alone usually leaves the color behind, and why the right order matters.

This guide covers the three methods (strip, sand and bleach), which one your piece needs, how to deal with dark stain that won’t budge, and how to lift the other kind of stain, the spots and rings on finished wood.

What You’ll Need

The kit for a typical piece of furniture. The first three do most of the work; the sanders make the sanding part fast.

Also: chemical-resistant gloves, eye protection, plastic sheeting, mineral spirits or the cleanup your stripper’s label calls for, and 80, 120, 150 and 180-grit abrasives.

First, Know What You’re Removing

Most stained furniture has two layers: the stain, which is color that has soaked into the wood fibers, and a clear topcoat over it, such as polyurethane, varnish, lacquer or shellac. Two quick checks tell you what you’re dealing with:

• Is there a topcoat? Drop a little water on the surface. If it beads and sits there, there’s a finish on top. If it darkens the wood and soaks in, the stain is exposed, which is common on decks and fences.
• Is it solid wood or veneer? Look at an edge or the end grain. If the grain on the top doesn’t continue down the edge, or you see a thin layer over plywood or particleboard, it’s veneer. Veneer can be sanded only very lightly.

Is It Better to Sand or Strip Stained Wood?

On most furniture the answer is both, in that order. A stripper is the fastest way to take off a clear topcoat, and sanding a thick poly finish is slow and clogs paper. But stripper won’t pull out much of the stain that has soaked into the fibers, so after stripping you sand to remove the color.

• Strip first when there’s a thick film finish, carved details, turned legs, or veneer you can’t sand hard.
• Sand only when the piece is solid wood with flat surfaces and a thin finish, or bare stained wood with no topcoat.
• Add bleach when stain is still in the grain after stripping and you can’t sand any deeper.

Method 1: Strip the Topcoat

Citristrip Paint & Varnish Stripping Gel

Citristrip removes varnish, lacquer, polyurethane and shellac from wood, according to the maker. It’s a gel, so it clings to legs and vertical panels, and it stays wet and active for up to 24 hours, which gives it time to work through several coats. It contains no methylene chloride or NMP and is sold for indoor use; still wear gloves and eye protection and keep the room ventilated. For other options, see my picks for the best paint stripper for wood.

How to Strip the Finish Off Stained Wood

1. Set up. Work outside or with good airflow, on plastic sheeting. Remove hardware and take off drawers and doors.
2. Apply a thick coat. Brush the gel on generously in one direction. Don’t brush back and forth: let it sit undisturbed.
3. Wait. Follow the label and check a small spot with the scraper. When the finish lifts and wrinkles down to the wood, it’s ready. Old, thick finishes take longer.
4. Scrape with the grain. On flat surfaces use a scraper held low, going with the grain so you don’t gouge.
5. Scrub the details. Use a fine sanding sponge or a stiff nylon brush on carvings, spindles and grooves.
6. Clean the residue. Wipe down with the cleaner your stripper’s label specifies and let the wood dry fully before sanding.

If the topcoat is polyurethane, my guide on how to remove polyurethane from wood covers the solvent test, longer dwell times and sanding it off.

Bahco 665 Carbide Scraper

A plastic putty knife works, but a carbide scraper lifts softened finish faster and doesn’t dull. The Bahco 665 has a 2-1/2″ blade and a two-hand handle for steady pressure, and it takes four blade shapes for different profiles. Bahco says the carbide stays sharp up to 50 times longer than steel. Keep it flat and light on softwoods like pine: a carbide edge cuts wood as happily as finish.

3M Fine Sanding Sponge

For stripper residue in the grain and on curved parts, a flexible sanding sponge does what a brush can’t. This 3M fine-grit block is extra large (2-7/8 x 8 in), can be used wet or dry, and rinses clean to reuse. It also handles the final hand-sanding on legs and spindles once the piece is dry.

Check price on Amazon

Method 2: Sand the Stain Out

Once the topcoat is gone, the stain left in the wood comes out with sanding. How deep it goes depends on the wood and the stain: on dense hardwoods like maple it’s often just below the surface, on open-pored oak and soft pine it goes deeper and hangs on in the pores.

The Grit Sequence

• 80 grit to cut through the stained layer on solid wood. Skip it on veneer.
• 120 grit to remove the 80-grit scratches and the last of the color.
• 150 to 180 grit to finish, before you re-stain or clear-coat.

Move one step at a time and clean off the dust between grits. The full chart is in my what grit sandpaper for wood guide.

For Flat Surfaces: Bosch ROS20VSC Random Orbital Sander

Tabletops, drawer fronts and door panels go much faster with a random orbital sander. The Bosch ROS20VSC has a speed dial from 7,500 to 12,000 OPM, so you can slow it down on veneer, and a pad dampening system Bosch designs to reduce swirl marks. Keep the pad flat and moving, and let the tool’s weight do the work. For bigger jobs, see my best sanders for furniture refinishing.

For Corners: DEWALT DWE6411K Sheet Sander

A round pad can’t reach into the inside corner of a drawer box or a frame-and-panel door, and stain left in a corner shows. A 1/4-sheet sander like the DEWALT DWE6411K (2.3 A, 14,000 OPM) has a square pad that gets right in. It clamps ordinary sandpaper, so you can cut sheets in any grit. For tighter spots, a triangular detail sander is the next step.

Method 3: Bleach What Won’t Come Out

When color is still trapped in the grain after stripping and you can’t sand deeper, wood bleach is the next step. There are three kinds, and each works on a different stain:

• Two-part wood bleach (A/B, sodium hydroxide and hydrogen peroxide): lightens the wood itself and most pigment and dye stains. The strongest option, used for making dark wood lighter.
• Oxalic acid: for black water marks and iron stains, the dark rings from a plant pot or a steel tool left on oak. It doesn’t lighten ordinary stain much.
• Household chlorine bleach: can remove some dye stains without changing the wood’s natural color much.

Whichever you use, follow the label, neutralize and rinse as it directs, let the wood dry completely, and sand lightly afterward because bleach raises the grain. Then finish as normal.

How to Remove Dark Stain from Wood

Dark stains, especially on oak and pine, are the hardest to remove because pigment packs into the open pores and soft earlywood. Work in this order: strip the topcoat, scrub the pores with a fine sponge or a brass brush, sand to 120 grit on solid wood, then use a two-part bleach on what’s left. Accept that open-pored woods may keep a little color in the pores: going a shade darker on the new finish hides it far more easily than chasing the last bit out.

Removing Stain from Tables, Doors and Decks

Wood Table

Strip the top and sand it with a random orbital, then treat the legs and apron by hand. The step-by-step is in my guide to sanding and refinishing a table.

Wood Door

Take it off the hinges and lay it flat so the stripper doesn’t run. Panel doors have inside corners a round pad can’t reach, so use a sheet or detail sander there. See my best sanders for doors.

Deck

Deck stain has no topcoat over it and is weathered, so use a deck stain stripper made for exterior wood, or sand it off. My guide on how to sand a deck covers the process.

Removing Stains ON Wood (Spots, Rings and Grease)

Sometimes “stain” means a mark on finished wood, not the color in it. Try the gentlest fix first:

• White rings and cloudy spots are moisture trapped in the finish, not in the wood. They often fade with gentle heat (a hair dryer on low) or a light rub with a non-gel toothpaste on a soft cloth.
• Grease and grime: a few drops of mild dish soap in warm water on a damp, well-wrung cloth, then dry immediately.
• Black rings: the water has reached the wood and reacted with it. That needs the finish removed and oxalic acid, as above. My guide on how to remove water stains from wood walks through both kinds of ring.
• Ink and marker: if it’s in the finish, a light rub with mineral spirits may lift it; if it’s in the wood, it’s a strip-and-sand job.

After the Stain Is Gone

Clean the dust, fill any holes with a stainable filler (see my best wood filler picks), test your new stain on the underside, then apply the finish. If you’re using polyurethane, my guide to sanding between coats of polyurethane covers the part that decides how smooth it ends up. And if the piece is painted rather than stained, the process is different: see how to strip paint from wood.

Stuck on a piece that won’t give up its color? Tell me the wood and the finish in the comments and I’ll suggest the next step.

The best way to strip paint from wood depends on the piece: a gel chemical stripper for furniture, carvings and anything with detail, a heat gun and scraper for thick layers on doors and trim, and a sander only for flat surfaces with a few thin coats. Whatever the method, if the paint could be from before 1978, test it for lead first.

Stripping paint is slow, messy work, and the method you choose decides whether you end up with clean wood ready for stain or with gouges, scorch marks and paint still stuck in every corner. Below: how the four methods compare, step-by-step instructions for each, how to sand paint off wood when sanding is the right call, what to do for furniture, doors and cabinets, and the tools that make it easier.

The 4 Ways to Strip Paint from Wood, Compared

Step 1: Test for Lead Before You Start

This comes before any method. The EPA’s guidance for do-it-yourselfers says: “If your home was built before 1978, it may have lead-based paint; the older your home, the more likely it has lead-based paint.” The same applies to old furniture, doors and trim that came from an older house. Sanding, scraping and burning lead paint all release lead into dust or fumes.

• Test it. The EPA recognizes two test kits for wood, LeadCheck and D-Lead, when they are used by a Certified Renovator. For the most reliable answer, the EPA points to a certified lead inspector or risk assessor.
• If it is lead, or you can’t rule it out: the EPA’s DIY guidance recommends methods that keep dust down, including wet sanding with wet-dry sandpaper or a sanding sponge, a low-temperature heat gun under 1,100°F, and a chemical stripper, with the area sealed off and cleaned with a HEPA vacuum. Many people hire a lead-safe certified contractor at this point.
• If it is not lead: still wear a respirator and eye protection. Old paint dust, stripper fumes and heat-gun fumes are all worth avoiding.

Step 2: Prepare the Piece and the Space

• Remove hardware, hinges and knobs. Take doors off their hinges and lay them flat if you can; strippers and scrapers work far better on a horizontal surface.
• Work outdoors or in a well-ventilated room, with plastic sheeting under the piece to catch paint and sludge.
• Wear chemical-resistant gloves, eye protection and a respirator suited to what you are using.
• Clean off grease and dirt with a mild detergent and let the surface dry.

Method 1: Chemical Paint Stripper

A chemical stripper softens the paint so it can be scraped or wiped off, and it is the only method that reaches into carvings, turnings and molding profiles without damaging them. Gel and paste strippers are easier than liquids because they cling to vertical surfaces and stay wet longer. I compare the gels, pastes and liquids worth buying in my guide to the best paint stripper for wood.

How to Strip Paint from Wood With a Chemical Stripper

1. Test a small area to see how long the stripper needs on your paint.
2. Brush on a thick coat with an old natural-bristle brush, in one direction. Don’t brush it back and forth; a thick, undisturbed layer works better.
3. Keep it wet. Covering the stripper with plastic wrap slows evaporation, which matters on multiple layers.
4. Wait for the time on the label, until the paint wrinkles and bubbles.
5. Scrape with a plastic scraper on flat areas, following the grain, and use a stiff brush, a dental pick or a wooden skewer in details.
6. Repeat on areas where paint remains.
7. Clean the residue with the solvent the label specifies, then let the wood dry completely before sanding.

What Is the Most Effective Paint Remover for Wood?

For most DIY furniture work, a gel stripper that stays active for hours is the most effective, because it can soften many layers in one application. Citristrip, for example, says its gel stays wet and active for up to 24 hours. Faster, harsher strippers exist, but they give you less working time and are harder to use safely indoors. “Safer” labels don’t mean harmless: Citristrip contains no methylene chloride, yet its listing still carries a California warning for N-Methyl-2-pyrrolidone, so gloves and ventilation still apply.

Method 2: Heat Gun and Scraper

A heat gun softens paint in seconds so it lifts off in ribbons. On a door or a long run of trim with many coats, it is the fastest method there is, and it makes no dust. I compare models in my guide to the best heat gun for paint removal. For the full technique, step by step, see my guide on how to remove paint with a heat gun.

How to Strip Paint With a Heat Gun

1. Start on the lower setting and hold the nozzle a couple of inches from the surface.
2. Move it slowly over a small area until the paint blisters and bubbles. Don’t stop in one spot.
3. Scrape the softened paint right away, with the grain, keeping the scraper at a low angle, while you heat the next section.
4. Drop hot paint scrapings into a metal container, not onto plastic sheeting or the floor.

Safety: keep the heat away from window glass, which can crack, and from gaps in walls, where dust and old paper can smolder unseen. Keep a fire extinguisher nearby and check the area again after you finish. For old paint, stay under the EPA’s 1,100°F guideline. Check your heat gun’s maximum: some variable models go well past it, while the Wagner HT1000 below tops out at 1,000°F.

Method 3: Scraping

If the paint is already failing, like the flaking boards in the photo above, a sharp scraper removes most of it with no heat or chemicals. A carbide scraper stays sharp far longer than a steel one. Pull it toward you with the blade almost flat and let the edge do the work; digging in at a steep angle leaves gouges you then have to sand out.

Method 4: How to Sand Paint Off Wood

Sanding is the quickest method on flat surfaces with a few thin coats, and it is always the last step after stripping or heat, to clean off what is left and prepare the wood for finish. It is also the method that makes the most dust, so it is the one to avoid entirely on paint that might contain lead.

Can You Sand Paint Off Wood?

Yes, on the right piece. Sanding works best on flat, solid wood with one or two coats: a tabletop, a shelf, a door laid flat, deck boards, siding. It works badly on carvings, turned legs and moldings, where the paper rounds over the crisp edges before the paint in the hollows is gone, and on veneer, which a coarse disc can cut through in seconds. On thick, layered paint, soften the bulk with a heat gun or a gel stripper first and sand only what is left. And if the paint could predate 1978, test it before you sand at all (Step 1 above).

Which Sander to Use

• Belt sander: the fastest on large flat stock, and the easiest to gouge with. Keep it moving with the grain, use a low speed so the paint doesn’t melt onto the belt, and follow it with an orbital sander to erase the straight scratches. More models in my belt sander reviews.
• Random orbital sander: the safest single tool for furniture, doors and anything curved. Bosch rates the Turbo mode of its GET65-5N at three times the stock removal of its normal random-orbit mode, so one tool strips and finishes.
• Detail or mouse sander: for corners and the inside edges of frames that a round pad can’t reach. Slow on paint, so scrape first.
• Sanding block or sponge by hand: for profiles and moldings, after a stripper has done the heavy work.

I compare specific models for this job, including belt sanders, the Bosch and a belt file for narrow edges, in my guide to the best sanders for removing paint.

What Grit Sandpaper to Remove Paint from Wood

Start at 60 or 80 grit for one or two coats of paint. For thick, layered paint, drop to 40 grit, but only on solid wood and only for the first pass. Once the paint is gone, step up through 120 and finish at 150 to 180 before new paint or stain, or 220 before a clear finish. Don’t skip from 60 straight to 180: the finer paper takes far longer to erase deep scratches than the in-between grits would. My guide to what grit sandpaper to use on wood has the full sequence for every job, and the sandpaper grit chart converts between grit standards. Once the paint is off, sanding the bare wood is covered step by step in how to sand wood.

Step by Step: Sanding Paint Off a Flat Surface

1. Test for lead, remove the hardware and set up outdoors or in a ventilated room. Wear a respirator and eye protection.
2. Scrape off anything loose or flaking first. Sanding loose paint only clogs the paper.
3. Connect the sander to a shop vac and set a medium speed, so the paint doesn’t heat up and smear.
4. Sand with the coarse grit in overlapping passes with the grain, letting the weight of the tool do the work. Don’t stop in one spot.
5. Change the disc or belt as soon as it glazes over with paint. A loaded abrasive only rubs and heats the surface.
6. When the paint is gone, step through the finer grits over the whole surface, then hand-sand the edges and corners.
7. Vacuum and wipe off the dust before primer, stain or finish.

If you haven’t used one before, read how to use an orbital sander first. For the corners a round pad can’t reach, a detail sander finishes the job.

How to Sand Paint Off Wood Furniture

On a dresser or table, sand the flat parts (top, sides, drawer fronts) with a random orbital sander, and treat the legs, spindles and carvings with a gel stripper and a brush instead. Watch the edges of tops and drawer fronts: many pieces are veneered, and the veneer can be thinner than a sheet of paper. If you see a different grain or a line of glue at the edge, stop sanding there and strip it chemically. More on the whole job in stripping paint from furniture below.

How to Sand Paint Off a Wood Door

Take the door off its hinges and lay it flat across sawhorses. A flat slab door can be sanded all over, starting with a belt sander or a random orbital at 60 or 80 grit. On a paneled door, sand the flat rails and stiles, and strip the panel profiles and moldings with heat or a stripper, because sanding them flattens the profile. Old doors are the most likely place to find lead paint, so test first. The door section below covers the rest.

What Is the Quickest Way to Strip Paint?

On a flat door or trim with many coats, a heat gun and a sharp scraper is the quickest. On a flat surface with only one or two thin coats, a belt sander or a random orbital sander at 60 grit is quicker still. On anything with carvings, turnings or molded details, a gel chemical stripper is slower to act but quicker overall, because you are not fighting the shape. For most projects the fastest route is a combination: stripper or heat for the bulk, then a quick sand for the rest.

How to Strip Paint from Wood Without Sanding

Use a chemical stripper or a heat gun to remove the paint, then clean up with the stripper’s recommended solvent and fine steel wool or a stiff brush. On carved or delicate pieces, this is often the better route anyway, because sanding rounds over crisp details. You will probably still want a very light hand-sanding with 180 or 220 grit before finishing, to smooth grain the stripper has raised.

How to Remove Paint Without Damaging the Wood

• Use a plastic scraper on softened paint, and keep metal scrapers at a low angle.
• Scrape and sand with the grain.
• With a heat gun, keep moving and stop as soon as the paint bubbles. Scorch marks go deep.
• Let the stripper do the work: another coat and more waiting is better than scraping hard.
• Avoid coarse grits and belt sanders on veneer, which can be thinner than a sheet of paper.

Stripping Paint by Project

How to Strip Paint from Wood Furniture

Chemical stripper is the default for furniture: it gets into joints, turnings and carvings without rounding them. Work one surface at a time, laid horizontal if possible. Then sand lightly and prepare for your new finish; my guide to sanding furniture to paint covers the next steps if you are repainting.

How to Strip Paint from a Wood Table

Strip the legs and apron with chemical stripper, and the top with stripper or, if it is solid wood with only a coat or two, with a random orbital sander. Check whether the top is veneer before sanding: look at the edge and end grain. Then follow my guide on how to sand and refinish a table.

How to Strip Paint from a Wood Door

Take the door off its hinges and lay it on sawhorses. A heat gun and scraper removes thick paint from the flat panels and stiles fastest; use stripper in the molded profiles around the panels. Finish with a sander on the flats; I recommend specific models in my best sanders for doors guide.

How to Strip Paint from Wood Cabinets

Remove the doors and drawer fronts and strip them flat on a bench. Use chemical stripper on raised-panel profiles, and protect the countertop and floor if you strip the cabinet boxes in place. Many cabinets are veneered plywood, so go gently with any sander. See my picks for the best sanders for cabinets.

Household Items for Stripping Paint: What Works and What Doesn’t

Home remedies get a lot of attention, but on painted wood their use is narrow:

• Vinegar: hot white vinegar can soften small areas of water-based paint, for example on a small wooden item, left on for a while and then scraped. It does little to oil-based paint and is not practical for a whole door or dresser.
• Baking soda and boiling water: a classic for stripping paint off metal hinges and knobs you have removed. Don’t boil wood.
• Dish soap: good for cleaning the surface before and after stripping, not for removing dried paint.

For anything larger than a small item, a commercial gel stripper or a heat gun will save you hours.

Tools That Make Stripping Paint Easier

Citristrip Paint & Varnish Stripping Gel

Best for Furniture and Detail

A gel that clings to vertical surfaces and, according to the maker, stays wet and active for up to 24 hours, long enough to soften several layers in one go. It contains no methylene chloride or NMP and is non-caustic; still use gloves and good ventilation.

Stuck on a stubborn piece? Tell me what it is, what the paint looks like and what you have tried in the comments, and I’ll suggest the next step.

To use an orbital sander, attach a hook-and-loop disc with its holes lined up, connect a vacuum, set the pad flat on the wood before you switch it on, and move it slowly in overlapping passes, about an inch per second, with no more pressure than your hand resting on it. Step up through the grits, clean the surface between each one, and switch off before lifting the sander.

That covers 90% of it. The other 10% is where swirl marks, gouged edges and burned-out pads come from, and it is what this guide is about. The steps below are written for a random orbital sander, the round-pad tool most people mean by “orbital sander”. If yours has a square pad, it is a sheet sander; I cover the differences at the end.

What You Need

• A random orbital sander, 5″ or 6″. If you don’t have one yet, start with my random orbital sander reviews.
• Hook-and-loop sanding discs in three or four grits, with a hole pattern that matches your pad (see my guide to the best sanding discs for random orbital sanders).
• A shop vac or dust extractor with a hose that fits the sander’s port. The onboard bag or canister catches far less. See the best shop vacs for dust collection.
• Safety glasses, hearing protection and a dust mask or respirator.
• Clamps or a non-slip mat to hold the workpiece.

How to Use an Orbital Sander, Step by Step

Step 1: Attach the Sanding Disc

Unplug the sander or remove the battery first. Knock the old disc off and brush any dust out of the hooks on the pad. Hold the new disc by its edges, line up its dust holes with the holes in the pad, then press it on from the center outward. The holes matter: if they don’t line up, the vacuum pulls through fewer openings and dust stays under the disc, where it clogs the paper and scratches the wood.

If your pad has 8 holes and the disc has 5, or you own sanders with different patterns, buy multi-hole or mesh discs, which work on any pattern. The disc should sit flat with no edge lifting. If it keeps flying off, the hooks on the pad are worn and the pad needs replacing, not the discs. Here’s how to find a replacement pad that fits your sander.

Step 2: Choose the Starting Grit

Start with the finest grit that removes the worst mark on the surface: 80 for old finish or rough boards, 120 for new lumber. Plan your sequence before you begin, for example 80, 120, 150, 180. My sandpaper grit chart lists the right start and finish grit for every job.

Step 3: Connect Dust Collection and Put On Your Protection

Connect the vacuum hose to the dust port. Beyond keeping the room clean, extraction makes the sander cut better, because dust trapped under the disc makes it skate and clog. Put on safety glasses, hearing protection and a dust mask. Fine wood dust is the part of sanding you don’t see and shouldn’t breathe.

Step 4: Secure the Workpiece

A random orbital sander pulls sideways as it spins. Clamp small parts to the bench, or put them on a non-slip router mat. Large panels and tabletops usually stay put under their own weight.

Step 5: Set the Speed

If your sander has a speed dial, use the top setting for stock removal on bare wood, and turn it down for finish sanding, for veneer, for sanding between coats and for anything that heats up and gums the paper, like old paint or resinous pine. The Makita BO5041, for example, goes down to 4,000 OPM; the Bosch ROS20VSC and DEWALT DWE6423K start at 7,500 and 8,000.

Step 6: Start the Sander on the Wood

Place the pad flat on the surface, then switch on. Starting it in the air and bringing it down spinning is the quickest way to gouge the wood, because the disc hits the surface at full speed and at an angle. The same applies at the end: switch off with the pad on the wood, and lift only when the pad has stopped.

Step 7: Move Slowly in Overlapping Passes

Move the sander in straight rows, slowly, about an inch per second, overlapping each row with the previous one by about half the pad. Then do a second set of rows across the first. With a random orbital sander you don’t need to follow the grain, because the random pattern leaves no straight scratches. Speed of movement matters more than you’d expect: moving fast feels productive but the abrasive does less work and the scratch pattern is less even.

Step 8: Let the Weight of the Sander Do the Work

Rest your hand on top to guide it and add no more than light pressure. Pressing down slows or stops the free rotation of the pad, and a pad that isn’t spinning freely leaves the repeating loops people call swirl marks. If the sander is not cutting, the disc is worn or clogged: change it.

Step 9: Keep the Pad Flat, Especially at the Edges

Never tilt the sander onto the edge of the disc to “dig in” on a spot. It cuts a dish into the wood, and heat from the edge damages the hook-and-loop pad. At the edge of a board, let the pad overhang a little, but not more than about a third of it, or the sander tips and rounds over the edge.

Step 10: Clean Between Grits and Check Your Work

Before each new grit, vacuum or wipe the surface, and change the disc. Then check the surface with a light held low and to the side. When the scratches from the previous grit are gone and the new pattern is even, move up. After the final grit, wipe with a tack cloth or a damp rag before applying finish.

Do You Push Down on an Orbital Sander?

No. Guide it, don’t press it. The weight of the sander plus your resting hand is enough. Extra pressure feels like it should cut faster, but it slows the pad’s rotation, heats the disc, clogs it faster and leaves swirls. Some sanders make this easy to feel: if the pad visibly slows when you lean on it, you are pressing too hard. Light pressure with a fresh disc is always faster than heavy pressure with a dull one.

The 5 Most Common Random Orbital Sander Mistakes

1. Too much pressure. Stops the random rotation and creates swirl marks. Guide, don’t push.
2. Starting or stopping off the surface. A spinning pad landing on wood at an angle gouges it. Pad down first, then switch on.
3. Tilting onto the edge of the disc. Digs a dish into the surface and cooks the pad’s hooks.
4. Skipping grits or not cleaning between them. The coarser scratches stay, or loose coarse grit gets dragged around by the finer disc.
5. Using a worn or clogged disc. Once the disc stops cutting, pressing harder only makes things worse. Discs are cheap compared with a ruined finish.

How to Use an Orbital Sander on Specific Jobs

How to Use an Orbital Sander on Wood Furniture

Use the orbital sander on the flat, open surfaces: tops, sides, drawer fronts. Stop short of inside corners and carvings, where the round pad can’t reach; finish those with a detail sander or by hand. If a piece has lots of corners, see my guide to the best detail sanders.

How to Use an Orbital Sander to Remove Paint

Start at 60 or 80 grit and a medium speed, because high speed melts paint and loads the disc in seconds. Keep the sander moving and change discs as soon as they clog. If the house or furniture could be from before 1978, test for lead before sanding at all. For big flat areas, a belt sander is faster; I compare both in my guide to the best sanders to remove paint, and chemical and heat methods in how to strip paint from wood.

How to Use an Orbital Sander on Hardwood Floors

A handheld random orbital sander works for a small room, a single damaged area or a light scuff between coats, but it is slow on a whole floor. Work in sections, keep the pad flat and always keep moving so you don’t leave a dip. For a full floor, a large orbital floor sander is the tool; my step-by-step guide on sanding hardwood floors with an orbital sander covers both.

Sanding Between Coats of Finish

Use 320 grit or finer at the lowest speed, a fresh disc and almost no pressure. You are only knocking down dust nibs, not removing finish. Stay well away from edges, where the finish is thinnest and easy to cut through.

What Are the Downsides of an Orbital Sander?

• It can’t reach inside corners. A round pad leaves an unsanded arc in every 90-degree corner.
• It is slower than a belt sander for heavy stripping and leveling large flat surfaces.
• Swirl marks if misused. Pressure, tilting and skipped grits all show up under stain.
• Discs cost more than plain sandpaper sheets, and you need the right hole pattern.
• Dust, unless you connect a vacuum. The onboard bag or canister is a compromise.

None of these are reasons not to own one; they are reasons to own a second tool for corners. My sheet sander vs random orbital sander comparison explains which pairs best with it.

Using a Sheet (Orbital Finishing) Sander Instead

Some tools sold as “orbital sanders” have a square pad that moves in a small fixed orbit and doesn’t spin. The technique is similar, with three differences: clamp a cut piece of ordinary sandpaper tight under both clamps so it doesn’t wrinkle; sand with the grain, because the fixed orbit leaves a more regular pattern; and use the square pad’s corners to get into inside corners, which a random orbital can’t do.

Random Orbital Sanders I’d Start With

All three are 5″ corded models with variable speed, which is what makes the speed advice above possible. My full comparison is in the best random orbital sanders guide, and cordless options are in my cordless sander reviews.

Still getting swirl marks? Describe your sander, grit and finish in the comments and I’ll help you track down the cause.

For most bare wood, start sanding at 80 or 120 grit and finish at 150 to 180 grit before paint or stain, or 220 before a clear finish on smooth hardwoods. Go no coarser than you need to remove the marks you can see, and move up one grit at a time. Between coats of finish, switch to 320 grit or finer and barely touch the surface.

That is the short answer. The right grit still depends on three things: what state the wood is in, what finish goes on next, and whether the wood is open-grained like oak or closed-grained like maple. Below is a grit chart, a job-by-job table, the rules for stepping through grits, and the mistakes that show up only after the stain goes on.

Wood Sandpaper Grit Chart

The grit number counts how fine the abrasive particles are: the higher the number, the smaller the particles and the finer the scratch they leave. Here is what each range is for on wood. For other materials (drywall, metal, car paint, plastics) and a grit finder that gives you the whole sequence, see the full sandpaper grit chart.

CAMI vs “P” Grits: Why Two Sheets Marked Differently Can Be the Same

Most sandpaper sold in US hardware stores uses the CAMI scale. European brands use the FEPA scale, marked with a “P” in front of the number (P120, P220). Up to about 220 the two scales are close enough to treat as the same. Above that they drift apart, and a P grade is coarser than the same CAMI number: a CAMI 320 is roughly a P400, and a CAMI 400 is roughly a P800. If you mix brands for fine work, check which scale each one uses. The full conversion, with particle sizes in microns, is in my sandpaper grit chart.

What Grit Sandpaper for Each Wood Job

What Grit Sandpaper for Wood Before Painting

Paint hides scratches that a stain would show, so you can stop earlier. On bare wood, 120 followed by 150 gives primer enough tooth to grip. On wood that is already painted and sound, you are not trying to reach bare wood at all: scuff the old paint with 120 to 150 until the gloss is gone, then clean off the dust. Sand the primer coat lightly with 220 before the topcoat. My guide on how to sand furniture to paint walks through the whole job.

What Grit Sandpaper for Wood Before Staining

Stain is where grit matters most, because the scratches you leave become the pattern the stain soaks into. General Finishes, a finish manufacturer, recommends 120, 150 and then 180 on open-grain woods like oak, ash and mahogany. For closed-grain woods such as pine, maple and cherry it recommends stopping at 180 under an oil-based stain, and 150 then 220 under a water-based stain. Sand end grain one grit finer than the faces, because it soaks up more stain and turns darker. The full process, from the grit table by wood type to conditioner and wiping, is in how to stain wood.

What Grit Sandpaper for Wood Before Varnish or Polyurethane

A clear finish shows every scratch, but it still needs something to hold on to. General Finishes suggests sanding up to 150 under an oil-based clear coat and to 150 or 220 under a water-based one. On a smooth hardwood with no stain, 180 or 220 is a good final grit.

What Grit Sandpaper for Wood Furniture and Tables

For a piece with an old finish, start at 80 to break through the finish, go to 120 to remove those scratches, and finish at 180 for stain or 220 for a clear coat. Use a random orbital sander on the flat top and hand-sand or use a detail sander on legs and edges. I cover the whole process in how to sand and refinish a table.

What Grit Sandpaper for Wood Floors

Floors are the exception to “start fine”. A drum or orbital floor sander usually begins at 36 or 40 on an old finish, then 60, then 80 or 100, and finishes at 100 to 120 so the floor finish can grip. The full sequence, including the edges, is in my guide on how to sand hardwood floors.

What Grit Sandpaper for Wood Filler

Let the filler dry completely first. Level it with 120 grit on a sanding block, keeping the block flat so you don’t dish the soft filler below the wood around it, then finish the repair with the same grit as the rest of the surface.

How to Step Through Grits

Start With the Finest Grit That Does the Job

The first grit has one task: to remove the worst defect on the surface, whether that is a planer ridge, old finish or a dent. Try a medium grit first. If it has not removed the defect after a minute or two of sanding, drop to the next coarser grit. Starting coarser than you need only creates deeper scratches you then have to remove.

Move Up One Step at a Time

A common sequence is 80, 120, 150, 180, 220. Each grit’s only job is to remove the scratches of the one before it. When the surface looks evenly scratched at the new grit, with no deeper lines left from the previous one, move on.

Clean the Surface Between Grits

Loose grit from a coarse sheet gets dragged around by the next, finer sheet and leaves stray scratches. Vacuum or wipe the surface every time you change grit. A dust port connected to a shop vac helps a lot.

Check Your Work Under Low Light

Hold a light low and to one side of the surface, or wipe it with mineral spirits. Scratches that are invisible under overhead light show up clearly, and it is much easier to fix them now than after the stain has made them permanent.

The Golden Rule of Sanding (and Other Rules That Matter)

There is no single official “golden rule”, but the one most woodworkers mean is this: don’t skip grits. Each finer grit is designed to remove the scratches of the previous one. Jump too far and the finer paper polishes the tops of the deep scratches instead of removing them, and they reappear under stain.

• Sand with the grain when you hand-sand or use a belt or sheet sander. Cross-grain scratches are the hardest to hide.
• Let the tool or the paper do the work. Pressing harder does not cut faster once the paper is dull; change the paper instead.
• Don’t over-sand. General Finishes warns that sanding too fine creates a surface so smooth it will not accept a finish properly. For stain, that means blotchy or pale color.

Can You Go From 60 Grit to 120 Grit?

You can, but it is a big jump, and it only works well with patience. The 120 grit has to remove 60-grit scratches that are about twice as deep as its own, which takes much longer than going 60, 80, 120. On a painted surface you will probably get away with it. Under stain, you will usually see leftover 60-grit swirls. If you want to save a step, skip in the middle of the range, not at the coarse end: going from 120 straight to 180 is much safer than 60 straight to 120.

Is 80 Grit Too Rough for Wood?

For a final surface, yes: 80 grit leaves scratches that show through paint and especially stain. As a starting grit it is often the right choice, for stripping an old finish, leveling a glue-up or removing machine marks. On new, smooth lumber from the store, 80 is usually more than you need; start at 120.

Types of Sandpaper for Wood

Abrasive Minerals

• Aluminum oxide: the standard for wood, used on most sheets and sander discs. Tough, and the grains break down to expose fresh edges.
• Ceramic: the most aggressive and longest-lasting, good for coarse grits and heavy stock removal.
• Silicon carbide: very sharp, usually on waterproof black paper for wet-sanding finishes between coats.
• Garnet: a natural mineral that wears quickly and cuts gently, still liked for hand-sanding bare wood before finishing.

For how these minerals compare, including aluminum oxide vs silicon carbide and zirconia, see types of sandpaper explained.

Sheets, Discs and Mesh

Hand sanding and sheet sanders use 9″ x 11″ sheets that you cut or fold. A random orbital sander uses round hook-and-loop discs with holes that must line up with the dust holes on the pad. Mesh abrasives, like Mirka Abranet, pull dust through the whole surface instead of a few holes, so they clog less. If you need help choosing the tool itself, see my comparison of random orbital sanders and sheet sanders.

Anti-Clog Coatings

Many sheets and discs have a stearate coating, a dry lubricant that stops paint, finish and resinous softwood from loading up the paper. It is worth paying for when you are sanding old finish or between coats.

The Sandpaper I’d Keep in the Shop

For hand sanding, two grits of sheets cover most finishing work, and one assortment of discs covers the random orbital sander from stripping to between-coat sanding. For a full comparison, see my guides to the best sandpaper for wood and the best sanding discs for random orbital sanders.

3M Pro Grade Precision Sanding Sheets, 150 Grit
