What Grit Sandpaper Removes Paint From Wood? (60-80 Grit Guide)

Use 60 to 80 grit sandpaper to strip most paint off wood, then move to 120, 150, and 220 grit for a smooth finish before repainting or staining. If the piece predates 1978, skip dry sanding until you rule out lead paint. This guide covers grit choice by paint thickness, sander types, safe surface prep, and what the EPA requires before you sand old paint.

Understanding Sandpaper Grits

To effectively remove paint from wood, choose a coarse grit of 60-80 for initial removal, then follow with a finer grit of 100-120 for smoothing. The exact grit you need still depends on the paint’s thickness and how many coats are stacked on the wood.

How Sandpaper Grit Numbers Are Measured

Sandpaper sold in the US is graded on the CAMI (Coated Abrasive Manufacturers Institute) scale, standardized under ANSI B74.18. A lower number means a coarser, larger abrasive grain; a higher number means a finer, smaller grain. Two sheets marked “60 grit” from different CAMI-compliant brands should strip paint at roughly the same rate — that consistency is the whole point of the standard.

📊 The ANSI B74.18 coated-abrasive standard only defines grit sizes up to 600 — every finer number sold above that (1000, 1500, 2500 grit) is a manufacturer’s own extrapolation, not a standardized size. For paint removal you’re working in the 60-220 range, which is fully standardized. — Source: Sandpaper Grits: ISO vs CAMI

How Grit Affects Sanding Performance

A lower grit sandpaper (below 80) is coarse and removes more material per pass, which is why it’s the starting point for thick or multiple layers of paint. A higher grit sandpaper (above 120) cuts more slowly and is meant for removing residue and smoothing the surface, not stripping bulk paint. If you’re comparing grit against other abrasives, see how these numbers line up with steel wool grades.

Preparing The Surface

Before sanding, inspect the wood for nails, staples, or embedded debris that will tear the sandpaper or gouge the surface. Remove anything metal, then wipe away loose paint chips and dust with a dry cloth or brush — use soapy water first if the surface is grimy, and let it dry fully before you start sanding.

Wet Sanding Vs. Dry Sanding

Wet sanding uses water to lubricate the sandpaper and keep it from clogging with paint residue — it works well for finer grits and reduces airborne dust. Dry sanding is faster for stripping old paint layers but throws more dust, so wear a respirator rated for fine particulates, not just a dust mask.

Is It Safe To Sand Old Paint On Wood?

Lead-based paint safety is the one step most sandpaper-grit guides skip entirely. If your home or the furniture piece you’re working on was built or painted before 1978, dry sanding it can release lead-contaminated dust — a hazard for children and pregnant women in particular. Check with a lead test swab before you sand anything that old.

📊 The EPA’s Renovation, Repair and Painting (RRP) Rule requires lead-safe work practices — including using power sanders only with a HEPA-filter vacuum attachment, or misting the surface before sanding, scraping, or cutting — on any pre-1978 surface that’s being disturbed. Source: EPA, Lead-Safe Renovations for DIYers

If you’re not sure of the paint’s age, the EPA’s own guidance is direct about who’s affected:

“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.”

When lead is a real possibility, skip sanding altogether and use wet scraping or a lead-safe chemical stripper instead — both avoid generating airborne dust. For paint you’ve confirmed is lead-free, the coarse-to-fine sanding approach below is the faster route.

Best Sandpapers For Removing Paint From Wood

Once you’ve confirmed the paint is safe to sand, work through grits in order rather than jumping straight to a fine one — skipping steps just makes the coarse scratches take longer to remove later.

60 To 80 Grit Sandpaper

For several stacked layers of paint, 60 to 80 grit is the right starting point. It’s aggressive enough to cut through old coats quickly, but it can also gouge soft woods like pine if you press too hard — start light and add pressure gradually.

100 To 150 Grit Sandpaper

This middle grit cleans up whatever the 60-80 grit pass left behind — leftover paint flecks, rough patches, and swirl marks — without cutting deep enough to damage the wood underneath.

220 Grit Sandpaper

220 grit is the finishing step — it smooths the surface for new paint, stain, or clear coat and knocks down any remaining high spots without leaving visible scratch marks.

Choosing The Right Sander

Sandpaper by hand works fine for small areas, but a powered sander speeds up paint removal on doors, trim, decks, and tabletops. The three main types — orbital sanders, belt sanders, and detail sanders — each suit a different job.

Sander Type	Removal Speed	Best For
Random orbital sander	Moderate	Flat surfaces, general paint removal, low gouge risk
Belt sander	Fastest	Thick or multiple layers on large flat areas like decks and tabletops
Detail/mouse sander	Slowest	Corners, moldings, and spindles a flat pad can’t reach

For thin paint layers or detailed trim work, a random orbital sander is the safer default — it leaves a less aggressive scratch pattern than a belt sander and is far less likely to dig a low spot into the wood.

Other Methods To Remove Paint

Sandpaper isn’t the only option. Chemical strippers soften paint so it can be scraped off with a putty knife — effective on multiple layers, but they need ventilation and protective gloves. Heat guns loosen paint for scraping and work well on intricate trim, though overheating can scorch the wood. Power washing strips paint from large exterior surfaces like fences and decks quickly, but it’s messy and needs prep to protect nearby areas from runoff and debris.

How To Sand Painted Wood: Step By Step

Once you’ve confirmed the paint is safe to sand, this order keeps the process efficient and avoids re-sanding a spot twice.

1. Inspect and clean the wood: Remove nails, staples, and loose debris, then wipe away dust and dirt.
2. Confirm the paint is safe to sand: Test for lead if the wood predates 1978, and skip to wet scraping or a stripper if it tests positive.
3. Sand with 60-80 grit: Work in the direction of the grain to strip the bulk of the paint, using light pressure at first.
4. Step up to 120 grit: Remove remaining paint residue and blend out rough spots left by the coarse pass.
5. Finish with 220 grit: Smooth the surface until it’s ready for new paint, stain, or a clear coat.
6. Wipe away dust with a tack cloth: Any dust left behind will show up as grit under the new finish.

Sanding large surfaces by hand is slow — a random orbital or belt sander (see the comparison above) cuts the time significantly, as long as you still move through the grits in order and check your progress along the way.

Frequently Asked Questions About Sandpaper Grit For Paint Removal

What Grit Sandpaper To Remove Paint From Wood?

Use 60 to 80 grit sandpaper to remove paint from wood. This coarse range cuts through paint layers quickly without excessive effort, though you should follow up with 120 and 220 grit to smooth the surface afterward.

Will 120 Grit Sandpaper Remove Paint?

Yes, 120 grit sandpaper can remove paint from wood, but it works slowly and may not fully strip thick or multiple layers. Start with 60 or 80 grit for the bulk removal, then use 120 grit only for the smoothing pass.

What Is 220 Grit Sandpaper Used For?

220 grit sandpaper is used for the final smoothing pass before finishing — removing minor blemishes, blending out scratch marks from coarser grits, and preparing a clean surface for new paint, stain, or sealer.

What Sandpaper To Sand Down Paint?

To sand down paint on wood, start with 60 or 80 grit to strip the bulk of it, then switch to 120 grit for the remaining residue. Too fine a grit won’t remove paint effectively, and too coarse a grit can gouge the wood.

Is It Safe To Sand Old Paint That Might Contain Lead?

No, not by dry sanding. If the wood was painted before 1978, test it for lead first. If it tests positive, the EPA recommends wet scraping or a lead-safe stripper instead of sanding, since dry sanding creates airborne lead dust.

What Grit Sandpaper Works Best In A Random Orbital Sander For Paint Removal?

Start with a 60 or 80 grit disc in a random orbital sander to strip the paint, then switch to a 120 grit disc to smooth the surface. The random orbit pattern leaves fewer visible scratch marks than a belt sander at the same grit.

Can A Belt Sander Remove Paint From A Wood Deck?

Yes, a belt sander is one of the fastest ways to strip paint from a wood deck’s large flat boards. Start with 60-80 grit, keep the sander moving to avoid gouging, and switch to a random orbital sander for railings and spindles.

Conclusion

Start with 60 to 80 grit sandpaper to strip paint from wood, then move through 120 and 220 grit to leave a smooth, paint-free surface ready for a new finish. Before you sand anything that might predate 1978, confirm it’s lead-free — that single check matters more than which grit you pick first.
