Hey everyone, if you’ve ever tackled a home renovation or a small DIY project, chances are you’ve stared at a pile of old brick, unsure how to get it smooth enough for a new coat of paint, tile adhesive, or just a clean finish. A question I get all the time from fellow DIYers, contractors, and even other suppliers is this: Can abrasive pads be used for sanding brick? As someone who’s been in the abrasive pads game for over a decade, I’m here to break this down straight—no fancy jargon, just real talk about what works, what doesn’t, and how to get the job done right without ruining your brick or wasting your time. Abrasive Pads
First off, let’s get one thing clear: Brick isn’t like wood or metal. It’s porous, it’s brittle, and it’s made of clay that’s been fired, so it has a rough, uneven surface with tiny gaps and crannies everywhere. A lot of people assume any old abrasive pad will work, but trust me, not all pads are created equal. I’ve seen folks grab a random scouring pad from the kitchen sink and wonder why it’s taking forever to make a dent, or even worse, scratch the brick so bad it looks worse than before. Let’s start with the basics: What exactly do abrasive pads do? They’re designed to have tiny, hard particles (usually aluminum oxide, silicon carbide, or sometimes even diamond for heavy-duty stuff) bonded to a flexible or semi-rigid base, and they come in all different grits and hardness levels.
So, back to the main question: Yes, abrasive pads absolutely can be used for sanding brick—but only if you pick the right type, use the right grit, and follow the correct process. I’ve recommended abrasive pads for countless jobs ranging from refinishing old fireplace bricks to prepping exterior brick for a new mortar wash, and 9 times out of 10, they work way better than traditional sandpaper or even power sanders for smaller, more detailed areas. Wait, but why not just use a belt sander or an angle grinder with a sanding disc? Because those are way too aggressive for most brick surfaces, especially if you’re working on an old, historic brick wall. They can gouge deep grooves, wear down the mortar joints around the brick, or even cause the brick to crumble if you’re not careful. Abrasive pads, on the other hand, are more flexible and apply a more even, gentle cut—perfect for getting that smooth finish without causing damage.
Let’s dive into the different types of abrasive pads you should actually use for brick, because this is where most people mess up. First, grit size is everything. If you’re starting with really rough brick that’s covered in old mortar smears, paint, or efflorescence (that white powdery stuff you see on old exterior brick), you’re gonna need a coarser grit first. Think 40 to 80 grit pads. These are heavy-duty, have larger abrasive particles, and can cut through that tough gunk without too much elbow grease. But here’s the thing: You don’t want to stay on coarse grit forever. Once you’ve removed the bulk of the dirt and rough spots, you need to move to a medium grit—120 to 180 grit—to smooth out the surface and get rid of the scratch marks left by the coarse pad. And if you want a super smooth finish, like if you’re planning to paint the brick, you can even go to 220 or 320 grit for a final pass. That makes sense, right? Start rough, go medium, finish fine.
Now, the type of abrasive particle matters too. For most brick jobs, I recommend silicon carbide abrasive pads over aluminum oxide. Wait, why? Silicon carbide is harder and sharper, which makes it better at cutting through the dense, porous surface of brick. Aluminum oxide is more for metal or wood, it’s a bit softer and breaks down faster, so it won’t hold up as well on brick. Unless you’re sanding a very soft, new brick that’s not too tough, silicon carbide is the way to go. And if you’re doing a really heavy job, like removing thick layers of old paint from a large brick wall, you might even want to check out diamond abrasive pads—they’re expensive, but they last forever and cut through the toughest paint and mortar way faster than any other pad. I’ve had contractors use diamond pads for full exterior brick restoration jobs, and they swear by them because they don’t need to be replaced every 15 minutes like lower-grit pads.
But wait, hold up—before you grab your pad and start sanding, there are a few key tips you need to know to avoid making a mess. First, always test a small, hidden area of the brick first. Old brick is unpredictable—some types are way softer than others, and what works on one wall might scratch or crumble another. Grab a small section of brick that’s not visible, do a few passes with your 80 grit pad, and see how it reacts. If it’s leaving deep scratches or crumbling, back off—maybe use a finer grit or even a different type of abrasive. Second, don’t press too hard. I know it’s tempting to put all your weight into sanding that tough mortar smear, but abrasive pads work best with light, consistent pressure. Pressing hard will just cause the abrasive particles to break off faster, and you’ll end up with uneven scratches. Let the pad do the work, and move in circular or back-and-forth motions—whatever feels natural, just don’t scrub too aggressively in one spot for too long.
Another big mistake people make is not cleaning the brick as they go. Brick is super dusty, and when you sand it, all those tiny particles and dust get caught in the abrasive pad, which makes the pad less effective and can even scratch the brick more. Every few minutes, stop, brush off the pad with a stiff bristle brush, and wipe the brick down with a damp cloth (just make sure it’s not soaking wet—you don’t want to get the brick too damp, especially if you’re working on interior brick). That simple step will make your pad last longer and give you a much smoother finish.
Now, let’s talk about when abrasive pads might not be the best choice, because it’s not a one-size-fits-all solution. If you’re working on a really large exterior brick wall that needs to be sanded completely, power sanders like an orbital sander might be faster, especially if you’re using a coarse pad. But even then, I still recommend using abrasive pads for the edges, corners, and areas around window frames or mortar joints where power tools can’t reach. And if you’re dealing with historic brick that’s valuable or has delicate details, abrasive pads are probably your best bet—they give you way more control than power tools, so you won’t accidentally damage the brick’s original surface.
I get asked all the time if abrasive pads are worth the cost compared to, say, regular sandpaper. Let’s be real—high-quality abrasive pads are a bit more expensive than a roll of sandpaper, but they last way longer. I’ve had a single medium-grit silicon carbide pad last me an entire fireplace sanding job, whereas I would’ve gone through 10 or more sheets of sandpaper for the same job. Plus, pads are flexible, so they can conform to the curved surface of a fireplace or the uneven face of old brick, which regular sandpaper can’t do as well. That saves you time and money in the long run, even if the upfront cost is a bit higher.
Let me share a quick story to drive this home. Last year, a customer of mine brought in an old brick fireplace that had layers of soot, old paint, and crumbly mortar on the faces. They tried using a random orbital sander with a sanding disc first, and it gouged three of the bricks so bad that they had to replace them. Then they reached out to me, and I suggested they start with 60 grit silicon carbide abrasive pads, follow up with 120 grit, and finish with 220 grit. They spent a weekend sanding by hand (with a little help from a small orbital sander fitted with a pad adapter for the tight spots), and when they were done, the fireplace looked like new—no gouges, no damaged mortar, just a smooth, even surface that they were able to paint without any issues. They ended up ordering a bulk pack of our abrasive pads for a future deck project too, so that’s a win-win for both of us.
Now, if you’re planning to sand brick with abrasive pads, here’s a quick step-by-step guide to make sure you get it right, no matter your skill level. First, prep the area: Cover any floors, furniture, or plants near the brick to protect them from dust. You might want to wear a dust mask, safety goggles, and gloves too—brick dust is not something you want to breathe in. Second, clean the brick first: Use a stiff bristle brush or a pressure washer (on low pressure, so you don’t damage the mortar) to remove loose dirt, leaves, or loose paint before you start sanding. That will make the sanding way easier. Third, test a small hidden area to check for brick hardness, like I mentioned earlier. Fourth, start with your coarse grit pad (40-80 grit) to remove tough gunk, moving in light, even passes, cleaning the pad often. Fifth, move to medium grit (120-180) to smooth out scratches, then fine grit (220-320) for a final polish. Sixth, when you’re done, wipe the entire brick down with a damp cloth to remove all sanding dust, and let it dry completely before you paint, seal, or do any other work.
If you’re still on the fence about whether abrasive pads are right for your brick project, here’s a simple rule of thumb: If your job is small, detailed, or involves historic or delicate brick, go with abrasive pads. They give you control, they don’t damage surfaces easily, and they’re way more forgiving than power tools. If your job is a huge, open exterior wall and you want to get it done fast, you can pair power sanders with abrasive pad adapters (yes, those exist!) to get the speed of power tools with the flexibility and gentleness of pads.
At the end of the day, I’ve used and sold abrasive pads for years, and I can confidently say they’re one of the best tools for sanding brick—when used correctly. The key is picking the right grit, the right abrasive type, and not overdoing the pressure. Skip the cheap, generic abrasive pads from the hardware store that wear out after 5 minutes; invest in high-quality silicon carbide or diamond pads designed specifically for masonry, and you’ll save yourself a ton of frustration.
