Sandpaper sells at nearly every hardware counter and paint aisle in the country, so finding it is rarely the problem. Matching the abrasive to the job is. Home Depot, Lowe’s, Ace Hardware, Menards, Harbor Freight, Walmart, Rockler, Woodcraft, Eastwood, and Amazon all stock deep catalogs, and they do not stock the same things. Below: how to choose the right sandpaper, a grit chart, four grain materials compared, and which retailer carries what.

What Sandpaper Is and Who Needs It
Sandpaper is a paper, cloth, or film backing coated with bonded abrasive grain, used to cut, smooth, and polish wood, metal, drywall, plastic, and painted surfaces. The number on the back is the grit size: low numbers cut fast and leave deep scratches, high numbers refine and buff.
Four buyers dominate this aisle. Homeowners want one assorted pack. Woodworkers buy garnet sheets and ceramic discs by the box. Drywall finishers need rolls and sponges sized for pole sander heads. Auto body DIYers hunt wet and dry silicon carbide paper above 1000 grit. Refinishing hardwood is the biggest abrasive purchase most homeowners make, and our guide to where to buy wood flooring covers the material side. Manufacturing tolerance is the hidden variable: premium and bargain sheets differ in sheet life, not in the surface left on the workpiece.
What to Look For in Sandpaper: Features and Buying Criteria
Buy for grit range first, grain material second, brand third.
Grit number. The figure reflects the mesh screen the grain was sorted through, so 80 is coarse and 320 is fine. Jumping more than one step leaves scratches that telegraph through stain.
Grain material. Aluminum oxide handles almost everything, garnet is friendliest under stain, silicon carbide is built for wet work and metal polishing, ceramic outlasts all three.
Backing material and weight. Paper backings run A through F. A is lightest and most flexible for contour work, C or D is stiff enough for sanding blocks. Cloth and textile backings survive belt sanders, waterproof film survives water.
Anti-clog coating. Stearated sheets carry a zinc stearate dry lubricant that reduces clogging on primer, paint, and finish coats. Skip them under a water-based topcoat, since residue can affect adhesion.
The standard on the label. CAMI (North American) and FEPA (European, marked with a P) numbers both appear on US shelves. They are not the same scale, and they diverge as the abrasive gets finer.
| Grit Range | Category | Best Use |
|---|---|---|
| 40 to 60 | Coarse | Stripping paint, heavy stock removal |
| 80 to 120 | Medium | Smoothing lumber, shaping wood, old finish |
| 150 to 180 | Fine | Final sanding before stain, drywall patches |
| 220 to 240 | Very fine | Between coats of finish, scuff sanding |
| 280 to 320 | Extra fine | Polishing oil and lacquer finishes |
| 400 to 600 | Super fine | Wet sanding primer, clear coat, deburring |
| 800 to 3000 | Ultra fine | Automotive paint correction, mirror finish |
Grain Materials and Formats: Matching Abrasives to Your Tool
Four types of sandpaper grain cover nearly every project, and picking the right one saves more time than upgrading brands at the wrong number.
| Grain | Best For | Trade-off |
|---|---|---|
| Aluminum oxide (alumina) | Wood and metal, plastic, paint | Can burnish bare hardwood |
| Garnet | Bare hardwood before stain | Softest grain, wears fastest |
| Silicon carbide | Wet sanding, glass, tile, clear coat, emery-style metal work | Too brittle for heavy removal |
| Ceramic and zirconia | Hardwood, welds, belt sanders, hard metal | Highest price per disc |
Format matters as much as grain, since the sheet has to fit the tool you own. Open mesh discs on a shop vacuum also cut the airborne particulate matter that solid paper throws into the room.
- 9 by 11 sheets: the universal hand sanding size, torn into quarters for a block.
- Hook and loop discs, 5 and 6 inch: for a random orbital sander from Dewalt, Makita, or Festool.
- Quarter and third sheet clip-on pads: finishing palm sheet sanders.
- Belts in 3 by 21 and 4 by 24: benchtop and portable belt sander sizes.
- Rolls: drywall pole sanders and contour work in tight spaces.
- Sanding sponges, nylon-backed sanding pads, and drums for drill-mounted rotary tools.
Sequencing a refinishing job takes three passes. Prep varies by topcoat, so read the can; our where to buy Sherwin-Williams paint guide covers the finish side.
- Cut the old coating with 60 or 80 grit until you reach clean substrate.
- Level the surface with 120, working with the grain on wood.
- Move to 150 or 180 for stain, or 220 for paint, then vacuum and wipe.
What to Avoid When Buying Sandpaper
The costliest mistake is buying one grit and expecting it to do three jobs.
Jumping steps. Going from 80 straight to 220 hides coarse scratches instead of removing them. They reappear the moment stain hits the wood.
Premium paper for demolition. Coarse stripping destroys any abrasive fast, so ceramic at 40 grit is money burned in ten minutes.
Mixing CAMI and FEPA numbers. Treating 220 and P220 as identical can leave a visible scratch pattern in a surface you thought was ready.
Unbranded bulk lots. Cheap import packs often skip the adhesive resin bond that keeps grain attached, and shedding shows on the first pass. If a listing will not name the abrasive material, that is your answer.
Where to Buy Sandpaper In Store
Every general hardware chain stocks basic aluminum oxide sandpaper. Selection depth is where they split.
Home Depot
Home Depot, the largest home improvement chain in the US, carries the widest DIY range: 3M, Diablo, Gator, Norton, and Dewalt in sheets, sponges, belts, and discs. Look in paint, not hardware. Check the category page, since stock is listed per store.
Lowe’s
Lowe’s carries the same core brands and is dependable for 3M SandBlaster and Norton 3X. Bulk rolls for drywall pole sanders turn up here more often than at a neighborhood store. Browse their selection.
Ace Hardware and Menards
Ace keeps a tighter range but does well on small assorted packs. Menards, the Midwest chain, is worth checking during its periodic rebate promotions. Both are convenient when the list also includes where to buy tools or a measuring tape.
Harbor Freight
Harbor Freight sells Warrior and Bauer abrasives at the lowest sticker price in the market, which suits rough carpentry and deck work. Finish carpenters step up a tier for surfaces that take stain. See the lineup.
Walmart and Auto Parts Counters
Walmart stocks 3M multi-packs in the paint aisle year round. O’Reilly Auto Parts and similar counters keep wet and dry sheets, the fastest local route to 1000 grit or finer. Call ahead above 400, since hardware stores stock the fine grit end thinly.
Where to Buy Sandpaper Online
Order online when you need a number the local aisle skips, a bulk pack, or a specialty grain.
Amazon
Amazon, the largest online retailer in the US, lists most of what the big boxes carry plus import brands, contractor packs of sandpaper sheets, and grades above 1500. Read the grain material in the title, because unlabeled assortments are common. Browse the selection.
Rockler, Woodcraft, Klingspor, and Empire Abrasives
Specialty woodworking dealers stock Mirka, Klingspor, Festool, and real garnet paper the big boxes rarely shelve. Expect a higher price per sheet for longer grain life. Rockler and Klingspor ship direct; Empire Abrasives cuts belts to order.
Eastwood and Northern Tool
Eastwood and Northern Tool focus on automotive silicon carbide Wetordry paper and dual action sander discs. Shortest path to 1000, 1500, 2000, and 3000 for paint correction.
How Much Should You Pay for Sandpaper
Abrasives are priced per sheet or per disc, and the spread is wider than the shelf tag suggests. As of July 2026, expect roughly these bands.
- Budget: store-brand and Warrior-grade sheets, about $0.30 to $0.60 each in multi-packs. Basic grain, short life.
- Mid-range: 3M SandBlaster, Norton 3X, Diablo, and Gator, around $0.75 to $1.50 per sheet, with better grain uniformity.
- Premium: Mirka Abranet, Klingspor, and 3M Cubitron ceramic discs, about $1.50 to $3 each.
Where paying more is wasted: the coarse range from 40 to 60. Heavy stock removal wrecks any abrasive within minutes, so premium and bargain sheets hit the trash on the same schedule. Spend at 150 grit and above.
Top Picks for Five Common Sanding Jobs
Chosen on grain type, format availability, and how many retailers carry them.
Best overall: 3M SandBlaster Pro assorted pack. A multi-grit box spanning stripping through finishing, on aluminum oxide grain that holds its cut through paint and primer. Where to buy: Amazon | Home Depot | Lowe’s | Walmart
Best budget: Gator Grit multi-grit sanding sheets. Serviceable aluminum oxide sandpaper at the lowest cost per sheet among name brands, easy to find at Home Depot. Where to buy: Amazon | Home Depot | Lowe’s | Harbor Freight
Best professional: Mirka Abranet mesh sanding discs. Open mesh pulls dust through the back of the disc instead of trapping it, which reduces clogging. Pair with a vacuum-ready random orbital sander. Where to buy: Amazon | Rockler | Woodcraft | Empire Abrasives
Best for woodworking: Klingspor garnet sanding sheets. Garnet self-fractures as it wears, keeping a cool edge on bare hardwood and a surface that takes stain evenly. The traditional wood finishing choice. Where to buy: Amazon | Klingspor Online | Woodcraft | Rockler
Best for auto body: 3M Wetordry automotive sheets. Silicon carbide grain on a waterproof backing, rated for wet or dry use on primer, clear coat, and final polish. Where to buy: Amazon | Eastwood | Northern Tool | O’Reilly Auto Parts
Start with the job, not the brand. Pull your coarse, medium, and fine numbers off the chart above, buy the cheapest thing you can find for the coarse pass, then spend real money at 150 and up. Above 600, order sandpaper online or drive to an auto parts counter.
Frequently Asked Questions About Buying Sandpaper
Which is rougher, 80 or 120 grit?
80 is rougher. Lower numbers mean larger particles, because the figure comes from the mesh screen count the grain was sifted through.
What is another name for sandpaper?
Abrasive paper is the industry term. Glasspaper, garnet paper, and sand paper all appear on packaging. Emery cloth is the cloth-backed relative, coated with emery, a natural corundum blend used mostly on metal.
Which numbers remove paint from wood?
Start at 60 or 80, move to 120, then finish at 150 or 180. One caution: homes painted before 1978 may carry lead paint, which should never be dry sanded. Test first.
What works best on drywall?
Use 120 or 150 on a pole or hand sander to feather joint compound, then 220 for the final pass. A sanding sponge leaves fewer swirl marks in inside corners.
When should a sheet be replaced?
Replace it the moment the cut rate drops, even if the grain looks intact. A glazed sheet burnishes instead of cutting and builds heat that can scorch wood. Loaded paper sometimes revives with a crepe rubber cleaning stick.
Is wet sanding worth it on a DIY paint job?
Yes, above 600 on clear coat or primer. Water carries away swarf, prevents clogging, and leaves a finer scratch pattern than dry work. A few drops of dish soap improve lubrication.
