Can I paint my concrete garage floor with interior latex paint?
No. Without the proper prep and paint, it will peel. You first need to prepare the concrete by using a combination cleaner and degreaser. If the surface is smooth, you need to use a concrete etcher so that the paint will adhere. Fill in any cracks or holes with a product like Dap Self Leveling concrete filler and sealant. Use a concrete floor paint like Behr’s 1 part epoxy garage floor paint, or Rustoleum’s 2 part epoxy garage floor paint. Behr and Glidden both have floor paint that would work fine on a floor you won’t be driving on. All of these paints can be tinted any color. It’s important to use a product that is made specifically for painting concrete floors — as opposed to concrete/masonry wall paint or regular latex paint — if you want it to last. Good luck!
