    Default Trying to get 3 layers of paint from concrete garage floor

    Just bought a 25 year old house. Previous owner has 3 layers of paint on the concrete garage floor. Have been scraping up with paint striper brush attached to drill, a metal pole sc****r. It's tough to get up. What would be the best way/product to get the 3 layers of paint up where it's just the concrete?

    aroundthe bend,

    You have a couple choices: You can use a chemical stripper, or you can rent a floor grinder. The floor grinder looks like a floor buffer but has diamond stones where the buffing brushes would normally be. These are often used by commercial outfits that do 2 part epoxy garage floor coatings. The bonus to the grinding is that the abraided floor that results will give better adhesion to the new paint or epoxy.

    If you just want to return to bare concrete, the chemical stripper will remove the paint without roughening the concrete.

    With 3 layers on the floor why would you want to re paint again? obviously your floor is rejecting paint.

    Clean the floor as mentioned and find another floor coating idea. Just google floor coating.

    A two-part epoxy floor paint has the best chance of holding if the surface is abraided. The one thing that might interfer with adhesion is too much moisture coming up through the concrete. To test for moisture, place a piece of plastic, such as a garbage bag, on the floor taped on all sides. After 24 hours, remove the plastic and look for moisture on it. If there is a lot of moisture, better not paint.

    The guys who do garage floors professionally will not guarantee the finish if moisture is present. They might still do it with a hold harmless agreement.
