Have you ever sanded a tabletop and ended up with swirl marks, uneven edges, or a finish that refuses to cooperate? The culprit is often not the sander itself but the accessories you pair with it. Sanding belts, discs, hand pads, and backing plates act like the shoes of your sanding process — pick the wrong type and you’ll slip, pick the right one and you’ll glide to a perfect surface. Getting your accessories right saves time, reduces waste, and helps you get pro-level results even on a weekend project.
When it’s time to stock up, you want reliable stores that carry quality brands, offer variety in grit and size, and make it easy to match accessories to your tool. Below are stores you’ll find across the US that consistently carry sanding supplies for hobbyists and pros alike.
Walmart is a convenient place to grab common sanding accessories — think sanding belts, hand sanding pads, and basic sanding discs. You can often find trusted brands like 3M, including items like a 3M cloth belt (for example, the 577F 80 grit cloth belt in a 1/2 in x 12 in size), along with budget-friendly third-party options. For quick fixes or one-off jobs, Walmart’s combination of in-store pickup and online ordering is handy.
The Home Depot is a favorite for DIYers and contractors who want both breadth and depth. You'll find premium sanding belts for belt sanders, a wide range of orbital sanding discs in various grits and materials, and specialty items like fiber sanding discs and ceramic abrasives. The staff can help match grit to project, and you’ll usually find accessories sized for common tools, from 3 in random orbital pads to 6 in sanding discs for larger sanders.
Lowe’s carries many of the same national brands as Home Depot but often stock different pack sizes and exclusive deals. Lowe’s is a reliable stop for sanding sheets, hook-and-loop discs, and sanding blocks that work well for cabinetry, trim work, and furniture repair. Their online inventory is useful when you want to check whether a specific grit or size is in stock at your local store.
If you’re on a budget but need a large quantity of sanding accessories, Harbor Freight is worth a look. They offer value packs of sanding discs and belts and often bundle sanding pads and backing plates at attractive price points. For light-to-medium use or for projects where you’re going through a lot of consumables, Harbor Freight can be a cost-saving option.
Ace Hardware is a great choice for quick, local needs. Their stores often carry specialty items in smaller quantities, which is handy when you need a specific grit for touch-up work. Ace stores tend to stock a curated selection of premium sanding pads and hand sanding blocks that appeal to woodworkers who prefer to shop locally and speak with knowledgeable staff.
Want a huge selection and fast shipping? Amazon delivers. From narrow specialty sanding belts measured in inches to bulk packs of 2 in and 3 in discs, Amazon’s marketplace brings together big brands and boutique suppliers. Be mindful of seller ratings and product reviews — they’re your compass to avoid counterfeit abrasives and to spot true-value packs.
Sanding accessories are more than just grit and size. Choosing the right type of abrasive and backing system influences finish, speed, and longevity. Here are the core categories to keep in your toolbox.
Sanding belts are the workhorses for belt sanders and portable wide-belt machines. They excel at rapid stock removal and flattening rough surfaces. Belts come in widths like 1/2 in, 3/4 in, 2 in up to several inches, and lengths measured in inches too. Materials range from aluminum oxide (good general purpose) to zirconia for aggressive metal and hardwood sanding, and ceramic for heavy-duty material removal. Look for cloth-backed belts, like the 3M cloth belts, when you need durability and consistent grit exposure.
Sanding discs attach to random orbital sanders and angle grinders. Sizes commonly used in woodworking are 3 in, 5 in, and 6 in. Hook-and-loop backed discs make swaps quick, while PSA (pressure-sensitive adhesive) discs adhere directly to the pad for a tighter fit. Discs come in various abrasives — garnet for finish sanding, silicon carbide for drywall and metal, and ceramic for tough hardwoods. Don’t forget foam pads for contour sanding and interface pads to soften the attack on curved surfaces.
Hand sanding remains indispensable for fine finishing and detail work. Sanding blocks, sponges, and hand pads let you feel the surface as you sand, and they're great for edges and inside corners where machines can’t reach. Backing pads in 4 in or 6 in sizes help convert a sanding sheet into a handheld tool. For delicate work, flexible sanding pads conform to curves and save you from gouges.
Don’t overlook the little helpers: dust extraction adapters, backup pads, mandrels for sanding drums, and sanding sleeves in sizes like 1/2 in or 1 in for drum sanders. A good dust collection attachment keeps grit out of your lungs and your finish cleaner, while quality backup pads reduce vibration and increase life of pads and discs.
Grit selection is like choosing cut sizes for a haircut — too coarse and you’ll leave big marks, too fine and you’ll waste time. Here’s a simple roadmap: start coarse to remove material quickly, then step down through finer grits to refine the surface. For example, begin with 60 grit for heavy stock removal, move to 120 grit for leveling, then finish at 180–220 grit for paint or stain-ready surfaces. For bare wood finishing before a clear coat, you may go up to 320 grit for extra-smooth surfaces.
Material matters too: aluminum oxide is your go-to for most wood projects; zirconia and ceramic handle metal and hard maple; silicon carbide excels on drywall and plastic. If you’re sanding lacquer or finish, opt for stearated discs or belts to reduce loading, and consider open-coat abrasives which resist clogging on resinous woods.
Want to get more miles out of every disc and belt? Treat them right. Keep belts aligned properly on your sander, avoid excessive pressure that overheats and gums up abrasive surfaces, and use dust extraction to prevent clogging. When sanding finishes or resinous woods, use abrasive cleaners or sanding belt wash to remove lodged debris. For discs, rotate them periodically on the pad so wear is even and the abrasive lasts longer.
Also, store abrasives flat and dry — exposure to moisture can degrade adhesives and warp backing. If you’re using hook-and-loop systems, keep the backing free of big chunks of debris so new discs seat firmly and don’t tear on use.
There’s a balance between cost and performance. If you’re a hobbyist doing occasional projects, value packs from big-box stores or value brands can offer great bang for the buck. For daily professionals, investing in higher-end abrasives from 3M, Norton, or similar brands pays off with longer life and more consistent finishes. Sometimes a mid-tier belt with better grain distribution means fewer passes and less labor — which is cheaper in the long run.
Consider mixing strategies: use budget belts for rough stock removal and premium belts for the final smoothing. That way you control costs while keeping finish quality high.
Sanding kicks up dust and small particles that you don’t want in your lungs or eyes. Always wear a dust mask rated for fine particulates or a respirator for heavy-duty sanding. Safety glasses are a must, and hearing protection helps with noisy belt or orbital sanders. Secure your workpiece and use clamps whenever possible to avoid slips. Take breaks to inspect your work, and keep your workspace ventilated to reduce dust buildup.
When sanding metals or finishes, watch for heat buildup — excess heat can discolor or burn a surface. Use light, even passes and let the tool do the work instead of forcing it.
Sometimes you need a weird belt size or a specialty abrasive like non-woven Scotch-Brite pads or ceramic fiber discs. Shops like The Home Depot, Lowe’s, and Amazon often carry a broad selection, but for oddball sizes check specialty suppliers or manufacturer direct channels. Shops that sell woodworking tools and industrial supply houses can source larger or uncommon sizes, and manufacturer websites may have compatibility guides to match a belt or disc to your tool’s model number.
If you frequently need specialty items, keep a small inventory of common backup sizes in your workshop — a couple of belts in your most-used widths and a set of 80, 120, and 220 grits for discs will save you time when a project hits a snag.
Different jobs call for different tactics. For furniture refinishing, you’ll likely use a mix of orbital sanders with 120–220 grit discs for smooth surfaces and hand pads for edges. For floor sanding, wider belts and coarser grits are your friends early in the process, followed by successively finer sanding to prep for finish. Auto bodywork demands specific abrasives like wet/dry silicon carbide sheets and fine-grit polishing discs. Having a project-specific kit makes prep and execution faster and more predictable.
Before you buy, double-check these essentials: the exact dimensions (width and length measured in inches), grit range you need, backing type (cloth vs paper), and compatibility with your tool’s speed and mounting system. If you’re buying online, read product Q&A and reviews to detect common issues like premature tearing, poor grit distribution, or adhesive failures. When possible, buy a small trial pack to test on scrap material before committing to bulk purchases.
Sanding accessories are small items with a big impact. The right belt, disc, or pad can turn a frustrating job into a satisfying one, and knowing where to find quality supplies — whether at Walmart for convenience, Home Depot and Lowe’s for variety, Harbor Freight for value, Ace for local service, or Amazon for selection — makes a huge difference. Pair that sourcing know-how with the right grit choices and care for your abrasives, and you’ll get cleaner finishes faster and with less effort.
If you keep one takeaway from this guide, let it be this: match the abrasive to the task, and don’t skimp on the items that directly affect finish quality. A little foresight saves a lot of sanding and frustration down the road.
Happy sanding — and may your surfaces be smooth and your projects rewarding.
