A wooden table that’s scratched, stained, or dulled with years of old finish can look brand new again with a proper sanding and refinishing job — and the cost is a fraction of buying a replacement. Whether it’s a coffee table, a dining table, or a family heirloom that’s seen better days, the process is the same: strip the old finish, work through the grit sequence, address any damage, and apply a fresh protective coat. Done right, the result genuinely looks better than new.
This guide walks you through every step with the specific grits, techniques, and tips that make the difference between a professional result and a patchy one. Let’s begin.
- 🔄 Electric sander — random orbital for flat surfaces; detail sander for corners and edges
- 📄 Sandpaper: 60 grit, 120 grit, 220 grit, 360 grit
- 🧱 Wood putty or epoxy filler (for deep scratches and dents)
- 🧹 Tack cloth and vacuum
- 🪣 Soft cloth and wood-safe cleaner
- 🎨 Wood stain or furniture oil (Tung oil or Danish oil recommended)
- 💎 Clear coat or polyurethane sealer
- 😷 Dust mask, safety glasses, gloves
How to Sand a Table in 5 Steps
Step 1 — Know Your Piece Before You Start
Five minutes of assessment before you pick up the sander saves hours of problems later. There are a few things worth confirming before you begin:
- 🪵 Solid wood vs. veneer — Solid wood tolerates aggressive sanding. Veneer is a thin decorative layer over a substrate (often MDF or plywood) and can be sanded through completely with coarse grit if you’re not careful. If you’re unsure, look at the underside or inside of a drawer for a raw wood edge — solid wood shows the same grain all the way through; veneer shows a different material underneath. With veneer, start at 120 grit minimum and use light pressure throughout.
- 🔧 Pre-existing damage — Check for nails or staples sitting proud of the surface (they’ll tear sandpaper and score the wood), loose joints that need regluing, and any deep dents that need filling before sanding begins. Address all of these before the sander comes out.
- 🎨 Existing finish type — Lacquer, varnish, polyurethane, paint, and wax all strip differently. If there are multiple old finish layers built up over years, a chemical stripper applied before sanding significantly reduces the work the sander has to do and produces better results.
Step 2 — Prepare Your Work Area
Sanding a table generates a substantial amount of fine wood dust that travels further than you’d expect. Work outside if possible, or in a garage with the door open. If you’re working indoors, close any doors to living areas and cover soft furnishings with dust sheets — fine wood dust settles on everything in the room.
A dust collector connected to your sander makes an enormous difference in keeping the workspace clean and reducing airborne dust. Even a basic shop vacuum with a sander attachment captures the majority of dust at source. If you have neither, a plastic drop cloth under the table at minimum.
Clean the table surface with a wood-safe cleaner before any sanding begins — grease, wax, and oil residues load sandpaper quickly and create uneven sanding. For old tables, a wipe-down with mineral spirits or white spirit removes wax buildup effectively. Allow to dry completely before sanding.
Step 3 — Strip the Old Finish
Start with 60-grit sandpaper on the electric sander for the initial material removal pass. The 60-grit cuts through old varnish, paint, and lacquer efficiently and removes surface damage quickly. Keep the sander moving continuously — pausing in one spot even briefly creates a low spot that will be visible in the finished result. Apply only light downward pressure; the sander’s own weight does most of the work.
Work in sections across the table, overlapping each pass slightly to ensure consistent coverage. After the full 60-grit pass, vacuum the surface thoroughly and wipe with a tack cloth before moving to the next grit — sanding debris left on the surface creates deep scratches when the next grit runs over it.
Move to 120-grit for the second pass — this removes the coarse scratch pattern left by the 60 and continues levelling the surface. By the end of this pass, all old finish, major scratches, and surface stains should be gone. If any remain, repeat the 120-grit pass rather than moving forward.
For deeper scratches, gouges, or dents that sanding alone won’t level out, apply wood putty or two-part epoxy filler at this stage. Press the filler slightly proud of the surface, allow to cure fully, then sand flush with 120-grit before proceeding. Moisten a rag with high-proof methylated spirit and wipe across the surface at this point — this raises the grain slightly and reveals any remaining problem areas under the light before you move to the fine finishing grits.
Step 4 — Refine to a Smooth, Even Finish
Switch to 220-grit for the third pass. This is the finishing sanding stage — the goal is to remove the 120-grit scratch pattern and bring the surface to a uniformly smooth feel. At the end of this pass, run your palm across every section of the table. There should be no detectable roughness, no ridges, and no areas that feel different from the rest. Any that do need another 220-grit pass to address.
Clean the surface again thoroughly with a tack cloth — at the fine grit stages, any dust left on the surface scratches rather than abrades. The table is now ready for stain application.
Step 5 — Stain, Fill, and Apply a Clear Coat
Apply your chosen furniture oil or stain according to the manufacturer’s instructions. For hardwood tables, Tung oil or Danish oil are excellent all-purpose choices — they penetrate the wood fibres rather than sitting on the surface, bringing out the natural grain and colour beautifully while providing genuine protection.
Apply the first coat, allow it to penetrate for the recommended time, then wipe away all excess before it becomes tacky. Critically — don’t allow the stain to dry completely into the surface before wiping. Stain that dries on the surface creates an uneven, blotchy appearance that’s difficult to correct. After wiping, allow the first coat to dry fully, then lightly sand with 360-grit to smooth any raised grain before applying subsequent coats.
Once you’ve achieved the depth of colour you want, finish with a clear coat of polyurethane or lacquer to seal and protect the surface. Two to three thin coats, lightly sanded with 360-grit between each, produces a durable finish that resists water, heat, and daily use far better than a single heavy coat.
Tips for Specific Situations
- 🎨 Painting rather than staining — If painting the table rather than staining, the prep process is identical through 220-grit. Apply a wood primer before paint for better adhesion and a more even colour result.
- 🔲 Corners and hard-to-reach areas — Wrap a sheet of sandpaper around a sanding sponge or your finger for inside corners and carved detail areas. A detail sander handles the flat edge areas and apron sections that the orbital can’t reach cleanly.
- 🪵 Veneer tables — Light 120-grit passes only, minimal pressure, and check constantly. If you see the veneer pattern changing colour or texture under sanding, stop immediately — you’re approaching the substrate beneath.
Frequently Asked Questions
A sanded and refinished table is one of the most rewarding furniture DIY projects — the transformation is dramatic and the result is something you’ll use and enjoy every day. Take your time with the grit sequence, never skip the tack cloth between passes, and don’t rush the finish coats. Any questions about a specific piece or finish type, drop them in the comments. Good luck with the project!
