How to Remove Paint From Concrete Blocks

Unwanted paint on concrete can present a big problem. Not only is paint frequently difficult to remove; concrete is a problematic surface for any project. Fortunately, there are some innovative products that can help you effectively remove unwanted paint from your concrete blocks. Depending on the type of paint and number of layers present, you may use one or several of the following steps in the process of getting your concrete clean again.

Things You'll Need

• Soy-based paint and sealer remover
• Plastic scraper
• Chemical paint stripper
• Face mask

Instructions

1. Begin with the least hazardous substance--soy based paint remover. This product comes in a thick gel that can be spread over the paint. Leave the gel to sit for 20 minutes or more. Using your scraper, remove the gel from this area and reapply over the next area of concrete.

2. Repeat step one until the gel no longer removes the paint. At this point, you can apply a new batch of gel from the container. If you have several layers of paint to remove, you may need to use the gel more than once on the same area.

3. If the paint does not respond to the gel or the layers are too thick, you may proceed to a chemical paint stripper. Move your project to a well ventilated area and wear a mask while working with the chemical stripper.

4. Following the manufacturer's directions, apply the paint stripper to your surface and scrape or wipe away the paint. Reapply as needed.

5. After the paint has been removed successfully, rinse the concrete with water to remove any residue.

Tips & Warnings

• If you prefer a different approach to removing the paint, you can try using a concrete grinder to wear down the surface until the paint is gone. If the area you are working with is very large, you may want to consider hiring a professional contractor who can remove the paint with a high powered shot blaster.
