How To Remove Paint From Concrete Floors (DIY Guide)
Recently, more homeowners are choosing concrete for their basements, garages, and home flooring. It is cheap, easy to maintain, and can be polished.
However, one downside to concrete is it is porous, which means it will absorb nearly everything. It will quickly absorb liquids such as paint. If you are wondering how you can remove paint from concrete floors, then check out our guide to help your floors look brand new again.
First Step - Which Paint is on the Concrete?
Before you begin, you need to know what kind of paint is on your concrete floors. Different paint types require different methods of removal.
Oil Paint
You can use denatured alcohol and a cotton ball to rub a small portion of the painted concrete. If you rub the cotton ball on the painted surface and nothing comes off, then it is likely oil paint.
Latex Paint
You can use the same trick for latex paint. Soak a cotton ball in denatured alcohol. If some of the paint comes off or becomes tacky, then it is latex paint.
Epoxy
This is used to seal a concrete floor to prevent spills and stains from penetrating the porous concrete material. You can do a water drop test by dropping a few small drops of water onto the surface of your concrete floor. If the water beads up, then it has an epoxy sealant on it.
