Removing concrete sealant from different surfaces like vinyl siding, driveways, or glass can be a challenge. You may not know how to get it off, and you may think that the only way to do so is to break out the power tools. We’re here to tell you that there are actually several ways to remove concrete sealant from your vinyl siding and other surfaces.

Vinyl Siding

Removing concrete sealant from vinyl siding is a matter of patience and persistence.

Here’s how to do it:

Step 1

Use a sharp knife to scrape off as much of the sealant as possible. It’s best not to use a razor blade because it can damage the siding. It might take some time. But keep at it until you’ve removed as much of the sealant as you can with your hands.

Step 2

Stick the blade of a putty knife under the sealant and pry it off in strips. If there are any stubborn spots, repeat this step until they’re gone.

Step 3

Wash off any residue with warm water and dishwashing liquid or a citrus-based cleaner like “Mr. Clean All Purpose Cleaner.” Avoid using bleach or ammonia-based cleaners because these will discolor or damage your siding.


  • Use a wire brush to remove loose sealant from the surface of the driveway. If you cannot get rid of all of it, try using a chemical stripper.
  • Apply a liquid solvent to any remaining sealant and let it stand for 15 minutes. If the solvent does not work, use a pressure washer to remove the sealant. This may take some time but will be worth it in the end. Because the pressure washer will also clean out any dirt that has been trapped in between layers of concrete sealant on your driveway.
  • Use steel wool or masonry sandpaper to smooth down any rough spots on your driveway surface. You can also use a concrete grinding machine if your driveway is very rough. This will allow any new sealant to adhere to the surface more easily.


One of the most frustrating things about a concrete sealant is trying to get it off your glass. If you’ve ever tried to get rid of the stuff, you know that it’s like trying to remove dried glue from a window frame. It just doesn’t want to go anywhere!

Luckily, there are some easy ways that you can get rid of this stuff for good and leave your glass as clean as possible. Here are a few simple tips:

  • Use warm water and dish soap on a rag or sponge. This will help break down the sealant so that it doesn’t stick as much when you’re scrubbing at it.
  • Use an abrasive pad like steel wool or sandpaper to remove any remaining bits of sealant after washing with dish soap and water. You might want to wear gloves while doing this part because it can be pretty messy!
  • If there’s still some residue left over after using steel wool or sandpaper, try using rubbing alcohol. This should bring everything off easily!


There are a few different products that can be used to remove the concrete sealants. Acetone, lacquer thinner, and paint thinner are all effective at breaking down the sealant. In most cases, a little bit of the product is enough to dissolve the sealant.

However, it is important to test the product in an inconspicuous area to make sure it doesn’t damage the concrete. Another option is to use a steam cleaner to loosen the sealant. This approach can be a little bit more time-consuming, but it is generally safe for concrete.
