What Grit Sandpaper for Refinishing Furniture? A Start-to-Finish Sequence

For most furniture refinishing, the sequence is simpler than the sandpaper aisle suggests: strip old finish starting at 80 grit, work up through 120 and 150, and stop at 180-220 before staining; scuff an existing finish at 220-320 before recoating; and sand lightly at 320-400 between finish coats. The two mistakes that actually ruin projects are skipping grits — which leaves deep scratches that stain turns into stripes — and power-sanding through veneer, which there is no good way back from. Here is the whole system in one reference table, then the reasoning, so you can adapt it to any piece.

The Master Grit Sequence Table

Two notes on reading the table. "Stop at" is a real instruction, not a minimum: sanding bare wood far beyond 220 burnishes the surface, closing the pores so stain sits paler and blotchier than the can's swatch. And the starting grit is a ceiling on aggression — if a lighter grit is cutting fine, there is no prize for starting coarser.

The One Rule: Never Skip More Than One Grit Step

Sandpaper does not polish wood; it replaces big scratches with smaller ones. Each grit's whole job is to erase the scratch pattern the previous grit left. The standard ladder — 80, 120, 150, 180, 220 — is spaced so each step can realistically erase the one before it. Jump from 80 straight to 220 and the fine paper rides over the deep 80-grit furrows, polishing their edges without removing them. The surface feels smooth to your hand, and then the stain floods those furrows and announces every one of them in high contrast.

The professional's check is raking light: shine a work lamp or flashlight across the surface at a low angle after each grit, and the previous grit's scratches jump out. A pencil trick makes it foolproof — scribble a few light pencil squiggles across the surface before each new grit, and don't move up until every squiggle is gone. When the pencil disappears, so has the old scratch pattern.

Cross-grain scratches are the worst offenders, because stain exaggerates any scratch that cuts across the fibers. Whatever tool you use for the heavy work, make the final pass at each grit by hand, with the grain.

The Veneer Warning: Check Before You Sand Anything

The fastest way to destroy a piece of furniture is to put a power sander on a veneered top. Modern face veneer commonly runs about half a millimeter thick — thinner than a credit card — and while older veneer can be thicker, you have no way to know what you have until you're through it. Edges go first: a random-orbit sander tips almost imperceptibly at the perimeter and cuts through the veneer in seconds, exposing a substrate that no stain will ever disguise. Once you're through, the honest options are paint or a re-veneering job.

So before any aggressive sanding advice applies, answer one question: is this piece solid wood or veneer? Our guide to telling solid wood from veneer walks the two-minute inspection — end grain, edge banding, grain matching, drawer interiors. If the answer is veneer, change the plan: strip old finish chemically instead of grinding it off, sand only by hand with a padded block, start no coarser than 150, and watch continuously for the warning signs that you're getting close — a subtle color shift, or a ghosting glue line. If the answer is "not sure," treat it as veneer.

What Each Grit Range Is Actually For

40-60 grit is for shaping and flattening — removing material fast. It almost never belongs on furniture; the scratches are deep enough that erasing them adds work rather than saving it.

80 grit is the standard opener for cutting through an old finish or leveling significant damage on solid wood. It clears film fast but leaves furrows you must fully erase.

100-120 grit is the transition zone: it erases 80-grit scratches and handles lighter stripping jobs on its own. If a finish is thin or mostly failed, starting here saves a step.

150 grit refines the surface and is a safe starting point for hand work on veneer after chemical stripping.

180-220 grit is the pre-stain finish line. Most stain manufacturers' directions assume a surface sanded to roughly this range — smooth enough to feel uniform, open enough to take color evenly.

320-400 grit is for between coats of finish: a feather-light pass that knocks off dust nibs and gives the next coat something to grip, without cutting through. Stearated ("no-load") paper resists clogging here.

600 grit and up belongs to rubbing out a fully cured finish for a hand-polished sheen — a finishing-nerd step that transforms a gloss topcoat, but strictly optional.

One economy note: worn paper lies about its grit. A clogged, dull sheet of 120 cuts like 220 while still leaving occasional deep gouges from debris. Change paper often; it is the cheapest part of the project.

Hand, Block, or Random-Orbit?

A random-orbit sander earns its keep on flat, solid-wood tops through the 180-grit stage: keep it moving, let its weight do the work, and never tip it near an edge. Switch to hand sanding for the final grit — a flat cork or rubber block on flat surfaces, working with the grain, erases the sander's faint swirl marks that otherwise appear the moment stain hits. Sanding sponges and folded paper handle curves, spindles, and profiles. On veneer, skip the power sander entirely; on carved detail, consider whether stripping plus a synthetic abrasive pad does the job with less risk than paper.

Grit Sequences for the Three Most Common Projects

Full strip and re-stain, solid wood table: chemical stripper or 80 grit to remove finish, then 120, 150, and 180 everywhere, finishing each grit with a with-the-grain hand pass. Vacuum and tack between grits so stray coarse particles can't scratch the clean surface.

Repaint over a sound finish: no stripping needed. Degrease, scuff everything at 220 until uniformly dull, prime per the paint label, then 320 lightly between coats. Paint hides grain but not scratches — it needs the same discipline, minus the coarse grits.

Recoat a tired but intact clear finish: clean thoroughly, scuff at 220-320, and go straight to topcoat, with 320-400 between coats. See our dresser-recoating guide for the full walkthrough.

When the Answer Is No Sandpaper at All

If your actual goal is reviving color and luster rather than changing them, you may not need abrasives at all. Solvent-based restorers — Howard Restor-A-Finish is the familiar example — are designed, per the manufacturer's directions, to blend minor scratches and white rings into an existing finish and refresh faded color with nothing more aggressive than a cloth or 0000 steel wool. For a piece whose finish is intact but tired, that path skips the entire grit ladder, and it is kinder to veneer than any sandpaper ever will be. Save the full sequence for the pieces that genuinely need new color or a new film — and when they do, respect the ladder, one grit at a time.
