According to Empire Abrasives, you don&#8217;t need a concrete sander because a grinder can handle all the prep work, and <a href=\"https:\/\/www.vevor.com\/floor-grinder-machine-c_11003\" target=\"_blank\" rel=\"noreferrer noopener\">floor grinders <\/a>come in different sizes.<\/p><figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><tbody><tr><td><strong>Tool<\/strong><\/td><td><strong>Best for<\/strong><\/td><td><strong>Typical result<\/strong><\/td><\/tr><tr><td><a href=\"https:\/\/www.vevor.com\/concrete-grinder-c_44180\" target=\"_blank\" rel=\"noreferrer noopener\">Concrete grinder<\/a><\/td><td>Removing thin coatings, leveling high spots, opening the surface<\/td><td>Even, textured to polished surface<\/td><\/tr><tr><td>Concrete floor sanding machine (orbital or drum)<\/td><td>Light smoothing and finishing, often after a grinder<\/td><td>Smoother surface, little material removed<\/td><\/tr><tr><td>Scarifier<\/td><td>Thick coatings and uneven slabs<\/td><td>Rough, grooved surface<\/td><\/tr><\/tbody><\/table><\/figure><p>According to Cat&#8217;s rental guide, grinders strip away top layers up to 1\/8 of an inch, but the scarifier digs deeper and strips up to 1\/4 of an inch per pass.

A wood floor sander isn\u2019t the same thing as a concrete floor sander. Wood sanders are designed for wood surfaces, and the paper is for wood; the Home Depot guide says you should only use abrasives meant for hard surfaces, not wood. As a result, a much harder surface would wear out the sanding paper quickly, leaving an uneven finish. Check the manual before you start, and if it doesn&#8217;t list concrete, choose a machine that does, such as a purpose-built<a href=\"https:\/\/www.vevor.com\/concrete-grinder-c_44180\" target=\"_blank\" rel=\"noreferrer noopener\"> concrete grinder<\/a> with diamond tooling.<\/p><h2 class=\"wp-block-heading\" id=\"h-which-sanding-pads-or-discs-work-on-concrete-floors\">Which Sanding Pads or Discs Work on Concrete Floors?<\/h2><figure class=\"wp-block-image aligncenter size-full\"><img decoding=\"async\" width=\"800\" height=\"450\" src=\"https:\/\/i.vevor.net\/wp-content\/uploads\/2026\/10\/03-concrete-floor-sander-pads-diamond-cup-wheels.jpg!webp\" alt=\"Concrete floor sander pads and diamond cup wheels.\" class=\"wp-image-86873\" srcset=\"https:\/\/i.vevor.net\/wp-content\/uploads\/2026\/10\/03-concrete-floor-sander-pads-diamond-cup-wheels.jpg!webp 800w, https:\/\/i.vevor.net\/wp-content\/uploads\/2026\/10\/03-concrete-floor-sander-pads-diamond-cup-wheels-300x169.jpg!webp 300w, https:\/\/i.vevor.net\/wp-content\/uploads\/2026\/10\/03-concrete-floor-sander-pads-diamond-cup-wheels-768x432.jpg!webp 768w, https:\/\/i.vevor.net\/wp-content\/uploads\/2026\/10\/03-concrete-floor-sander-pads-diamond-cup-wheels-600x338.jpg!webp 600w\" sizes=\"(max-width: 800px) 100vw, 800px\" \/><\/figure><p>A floor concrete sander requires diamond abrasive pads, discs, or abrasives that work on hard surfaces. According to the Home Depot guide, use diamond-grit sanding discs or sandpaper designed for hard surfaces, not wood. Start with a rough grit to strip or flatten, then move to finer grits.<\/p><figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><tbody><tr><td><strong>Stage<\/strong><\/td><td><strong>Grit (Home Depot guide)<\/strong><\/td><td><strong>Purpose<\/strong><\/td><\/tr><tr><td>Strip<\/td><td>40\u201360<\/td><td>Basic stripping of coatings and rough spots<\/td><\/tr><tr><td>Smooth<\/td><td>80\u2013120<\/td><td>Smooth finish and minor imperfections<\/td><\/tr><tr><td>Finish<\/td><td>200\u2013400 and higher<\/td><td>Smoothest finish<\/td><\/tr><\/tbody><\/table><\/figure><p>Pad bonds matter, too.

When choosing a concrete floor sander, select pads based on the surface condition and the finish you want to achieve&nbsp;<\/p><p>Other surfaces, such as walls and corners, require a different tool because a large machine can&#8217;t reach them. For this purpose, use an angle grinder with a cup wheel; the <a href=\"https:\/\/www.vevor.com\/power-angle-grinders-c_13801\" target=\"_blank\" rel=\"noreferrer noopener\">angle grinder category<\/a> includes shrouds and cup wheels. Match the wheel size and thread to your tool, and check the manual for approved abrasives. While a concrete floor sanding machine is better for large areas, an angle grinder can handle detailed edge work.&nbsp;<\/p><p>Edge work is usually more time-consuming than open-floor work, so schedule time for it and take frequent breaks, keeping the cord away from the abrasive material. Always wear eye and ear protection, since the hand-held tool shoots debris back at you and makes noise. Before starting concrete floor sanding, check that the guard and wheel are secure.

The guide on <a href=\"https:\/\/www.vevor.com\/diy-ideas\/clean-a-concrete-garage-floor\/\" target=\"_blank\" rel=\"noreferrer noopener\">cleaning concrete garage floors<\/a> covers this, and the slab should be completely dry before you proceed to the next stage.<\/p><p>Then fill in cracks and holes, as they become apparent during sanding. Use appropriate patches or filler based on the crack size, and apply and level it properly. Flexural cracks require use of flexible filler. Wait until it dries out completely before sanding it even with the rest of the concrete surface, since soft filler clogs pads and produces uneven results. The<a href=\"https:\/\/www.vevor.com\/diy-ideas\/garage-floor-crack-repair\/\" target=\"_blank\" rel=\"noreferrer noopener\"> garage floor crack repair<\/a> steps apply to most slabs.<\/p><p>When using a concrete floor sander, start with the coarse grit and operate it slowly by pushing it without leaning on it, since extra pressure doesn&#8217;t necessarily make it move faster. Home Depot&#8217;s advice for sanding is to work row-wise, then crosshatch in the opposite direction. Clean between grits by sweeping or vacuuming, or, if wet-sanding, clean out the slurry to avoid damaging the next pass with coarser particles.&nbsp;<\/p><p>The 7-inch<a href=\"https:\/\/www.vevor.com\/floor-grinder-machine-c_11003\/vevor-electric-concrete-floor-grinder-7-walk-behind-grinder-1-7hp-concrete-floor-polisher-1300w-grinding-machine-1720rpm-upgrade-brushless-motor-surfacing-grinder-for-granite-marble-stones-p_010509851176\" target=\"_blank\" rel=\"noreferrer noopener\">, 1.7HP Floor Grinder<\/a> is ideal for this type of project, and its manual explains the dry-sanding process using an industrial vacuum. Dry sanding creates silica dust, and OSHA&#8217;s silica rule for construction provides separate control measures for handheld and walk-behind grinders (29 CFR 1926.1153, Table 1). Check it against your machine and wear eye protection.<\/p><h3 class=\"wp-block-heading\" id=\"h-sanding-before-paint-versus-stain\">Sanding Before Paint Versus Stain<\/h3><p>For the stain, sand it thoroughly and strip off every speck of the previous coating because the stain is translucent, and any scratches, sealer, or glue will show through. Try it out on an inconspicuous area first. For paint, a clean, properly sanded surface matters more than a mirror-like finish. Follow the paint instructions for the desired profile.

According to Cat&#8217;s rental guide, renting eliminates the upfront cost of expensive tools you rarely use, and you can coordinate the rental time with the job duration. The quote may not include taxes, shipping costs, additional fees, or delivery, so confirm these in advance and ask whether there are penalties for completing the job after the rental period ends.<\/p><p>These tools often fall under the <a href=\"https:\/\/www.vevor.com\/floor-grinder-machine-c_11003\" target=\"_blank\" rel=\"noreferrer noopener\">category of floor grinders,<\/a> so the floor grinders availability page provides information on available sizes. Look for the concrete sander, concrete floor sander machine, and diamond grinder. Make sure you know what abrasives come with the machine, whether it includes a dust collection system, its power requirements, and how it will be shipped. Let them know about your future intentions (painting, staining, or tiling), and do not forget to ask about the weight.<\/p><p>If you plan to sand more than one floor, buying a small machine may be beneficial.
