How to Sand and Refinish a Table (Read This First!)

Refinishing a table is one of the highest-value furniture DIY projects you can take on. A dining table or coffee table that looks worn out, dated, or damaged can be transformed completely — and the cost is a fraction of buying a replacement piece of similar quality. The key is understanding the full process from start to finish before you begin, because the decisions you make early (particularly around stripping, grit selection, and finish type) determine everything that follows.

This guide covers the complete refinishing process for all table types — solid wood, veneer, non-wood surfaces — along with the sanding techniques, tool choices, and finishing tips that separate a professional result from a frustrating one.

🛠️ What You’ll Need:

🔄 Electric sander — random orbital for the main surface; palm sander for precision work
📄 Sandpaper: 80 grit, 120 grit, 220 grit
💨 Compressed air or tack cloth for dust removal between stages
🎨 Stain, paint, or clear varnish of your choice
🖌️ Medium to large brush for finish application
😷 Safety goggles, dust mask, gloves

The Complete 9-Step Process

Here’s the full refinishing process laid out end-to-end, so you can see exactly where each decision fits before you commit to any of them.

Step 1 — Gather Equipment and Assess the Table

Before buying anything, understand what you’re working with. Is the table solid wood, veneer, laminate, or another material? This determines your starting grit and how aggressively you can sand. Solid wood tolerates a full grit sequence from 80 upwards. Veneer — a thin decorative layer over MDF or plywood — can be sanded through if you use coarse grit or heavy pressure, so it requires a lighter touch starting at 120 grit. Laminate (Formica-type surfaces) cannot be sanded to bare material the way wood can; it needs a different approach covered in the non-wood section below.

Step 2 — Strip the Old Finish (80-grit)

Attach 80-grit paper to the orbital sander and make a full pass across the entire table surface to remove the old finish, scratches, and any surface damage. Keep the sander moving constantly in the direction of the wood grain — pausing creates low spots. Apply only light pressure; the sander does the work. Work in overlapping sections to ensure consistent coverage across the full surface.

⚠️ Don’t Skip Grit Levels: Jumping from 80-grit straight to 220-grit doesn’t save time — it wastes it. The 80-grit leaves scratches that are too deep for 220-grit to remove efficiently. Work through each grit stage in sequence: 80 → 120 → 220. Each stage removes the scratch pattern of the one before it. Skipping stages means spending much longer on the fine grits trying to remove marks they aren’t designed to tackle quickly.

Step 3 — Smooth with Medium Grit (120-grit)

Switch to 120-grit and make a second full pass across the surface. This removes the coarse scratch pattern left by the 80 and continues levelling any remaining imperfections. At the end of this pass, the surface should have no visible old finish, no major scratches, and should feel noticeably smoother than after the 80-grit stage. If rough areas or old finish patches remain, repeat the 120-grit pass before moving on.

Step 4 — Final Sanding Pass (220-grit)

The 220-grit pass is the finishing stage — it removes the 120-grit scratch pattern and brings the surface to the smooth, consistent texture that takes stain and finish evenly. Sand with the grain and use light pressure throughout. By the end, the surface should feel uniformly silky under your palm with no rough patches. Run your hand across the whole surface to confirm before moving on.

Step 5 — Address Corners and Hard-to-Reach Areas

The main sander can’t reach corners, the table apron, or any carved details. Use a palm sander or hand-sanding with folded sandpaper for these areas. Match the grit to wherever you are in the sequence — if you’ve reached 220-grit on the main surface, use 220-grit for the detail work too. Consistent grit across the whole table ensures stain absorbs evenly everywhere.

Step 6 — Clean Thoroughly

This step is more important than it seems. Any dust left on the surface will be trapped under the finish, creating a gritty texture that no amount of additional coats will fix. Use compressed air to blow dust out of the grain and any corners or crevices, then follow with a tack cloth wipe across the entire surface. The surface should be completely clean and dust-free before any finish goes on. If you don’t have compressed air, a vacuum with a brush attachment followed by a thorough tack cloth wipe works well.

Step 7 — Apply the First Coat of Finish

Load a medium to large brush moderately — not dripping, but confidently loaded — and apply the first coat in long, confident strokes following the grain direction. Work in one direction consistently and don’t go back over sections you’ve already covered; double-brushing creates lap marks in most stains and varnishes. Apply to one section at a time and keep a wet edge to avoid visible joins.

💡 Stain vs. Varnish — Apply Differently: If using a penetrating stain (oil-based or water-based), apply generously, allow it to penetrate for the manufacturer’s recommended time, then wipe away all excess before it becomes tacky. Stain left to dry on the surface creates a blotchy, uneven result. If applying a film finish (varnish, lacquer, polyurethane), apply thin coats and allow each one to dry completely before the next — thin coats dry evenly and build properly; thick coats sag, bubble, and take far longer to cure.

Step 8 — Additional Coats

Allow the first coat to dry fully (check the manufacturer’s time), then lightly sand with 220-grit to knock down any raised grain or minor brush marks before applying the next coat. Wipe with a tack cloth after this light sanding before the next coat goes on. Most stains benefit from 2–3 coats for good depth of colour and protection; polyurethane and varnish builds best with 3 thin coats. The between-coat sanding is what produces that glassy, professional finish — don’t skip it.

Step 9 — Final Inspection

Once the final coat is fully cured (not just dry to the touch — fully cured, which for oil-based finishes can be 24–72 hours), inspect the table under raking light at a shallow angle. This reveals any runs, brush marks, missed areas, or uneven sheen. Minor issues can be addressed with a very light 320–400 grit pass followed by a final thin top coat. Once you’re satisfied, the table needs its full cure time before heavy use — most finishes reach full hardness in 7 days.

Refinishing Non-Wood Tables (Laminate and Veneer)

Laminate and veneer tables need a modified approach — here’s what changes:

🟡 Laminate (Formica, melamine) — You cannot sand to bare material. Instead, clean thoroughly with soap and water, allow to dry, then lightly scuff the surface with 220-grit sandpaper to create a mechanical key for primer. Apply a bonding primer specifically formulated for non-porous surfaces, allow to dry fully, then apply your chosen paint or finish. Without the bonding primer, paint on laminate will peel within weeks regardless of how carefully it’s applied.
🟠 Veneer — Sand with 120-grit maximum, very light pressure, and check constantly. Veneer is typically only 0.5–2mm thick — it sands through quickly. The finish application process is identical to solid wood once sanded.

Choosing the Best Tool for the Job

The tool that suits your project depends on the table size and your goals:

🔄 Random orbital sander — The best all-round choice for most table refinishing. The orbital motion minimises directional scratch marks and the round pad handles flat surfaces efficiently. Suitable for the main sanding passes on any table size.
🖐️ Palm sander — Better than a random orbital for precision work around edges, corners, and table aprons. Slower for large flat areas but offers more control in confined spots.
📏 Belt sander — Fast material removal for heavily damaged or thick-finish tables, but aggressive and harder to control. Only recommended if you have experience with one — it removes material very quickly and can create uneven surfaces if not kept moving.

Frequently Asked Questions

Q: Can I sand a table without stripping it first?Yes — in many cases sanding directly is faster and produces better results than chemical stripping beforehand. If the existing finish is a single layer in reasonable condition (no peeling, no multiple coats of different old finishes), starting with 80-grit sandpaper removes it efficiently. Chemical stripping is worth doing first when there are multiple thick layers of built-up finish (particularly old paint), when the table has carved or recessed areas where sandpaper can’t reach, or when the existing finish is bubbling or delaminating. Sanding over a bubbling finish just moves the problem rather than resolving it.

Q: How do I refinish a table that’s not real wood?The key is identifying the surface material first. For laminate (plastic-coated board), clean thoroughly, scuff lightly with 220-grit, apply bonding primer, and paint — don’t try to stain it, as stain won’t penetrate. For MDF (medium-density fibreboard) without veneer, it sands and primes well but absorbs paint heavily at the edges — seal edges with extra primer coats. For wood-look vinyl wrap, the surface is usually not sandable in a useful way; repainting over vinyl wrap requires a flexible bonding primer specifically designed for it. When in doubt, test any primer or paint product on an inconspicuous area first before committing to the full surface.

Q: How do I know when the table is sanded enough before finishing?The palm test and the raking light test used together are the most reliable methods. Run your palm flat across the full surface — it should feel uniformly smooth with no detectable ridges or rough sections anywhere. Then hold a work lamp or torch close to the surface at a shallow angle — any remaining scratches, low spots, or inconsistencies show as shadows that are completely invisible under normal overhead light. When both tests pass, the surface is ready. One additional check: wipe the surface with a slightly damp cloth and let it dry. The raised grain that results shows any remaining imperfections more clearly than the dry surface does.

Q: What’s the best finish for a dining table that gets heavy daily use?For a dining table in regular use, oil-based polyurethane is the most durable choice — it forms a hard, water-resistant surface film that handles heat, moisture, and daily wear better than penetrating oils or water-based finishes. Apply three thin coats with light 220-grit sanding between each. The downsides: it takes longer to dry between coats (8–24 hours depending on conditions) and has a slightly amber tone that warms the wood colour. If you prefer a clear, natural look, water-based polyurethane provides similar durability with a clearer finish and faster drying time, but is slightly less robust against heat and impact. Penetrating oils (Tung, Danish) look beautiful but require more frequent reapplication and offer less protection against water rings and heat marks — better suited to occasional-use tables and coffee tables than a daily dining table.

Q: Can I change the colour of the table completely, or do I need to match the original?You can go any direction you want with stain colour — lighter, darker, or a completely different tone. Going lighter is slightly more demanding than going darker, because any remaining trace of old dark stain in the wood grain will show through a light stain. For a significant lightening job, sanding back to bare wood more thoroughly and using a wood bleach product before staining gives the most even result. Going darker is more forgiving. Painting in a solid colour gives the most complete coverage of any original tone regardless of direction. There’s no obligation to match the original — many table refinishing projects deliberately go in a different direction, and the results can be dramatic improvements on the original finish.

A refinished table looks better than replacement in one key way: you know exactly what the piece is, where it came from, and what it’s been through. That history is worth preserving. With the right process, the finished result looks genuinely professional and lasts for years. Any questions about a specific table or finish, leave them in the comments below. Good luck!
