Repainting a painted concrete floor
 Login/Join 
posted
I hope someone can give me some direction re: painted concrete floors. I recently purchased a home that is built on a slab. I removed all of the wall-to-wall carpeting to reveal painted concrete. The carpet pad was not glued to the concrete; therefore, the floors do not have any trace of mastic on them. They appear to be typical of a foundation poured in the 1950s--relatively smooth, just slightly pitted here and there. In some spots, wall paint (most likely a latex base) has splattered on the floor. I cannot determine with my untrained eye if the floor paint has been sealed with some sort of clear shellac or other type of sealant or if it is an epoxy paint.

My main question is this? If I clean the floor with a household cleaner (NOT Muriatic acid or a phospate-based cleaner, but just Pine Sol or an equivalent)and the current covering is an epoxy paint, then can I just repaint it with an epoxy paint made specifically for concrete floors? Would I be able to do the same, i.e., repaint the floor after a cleaning, if the floor is sealed with a shellac or some other sealant?

Any assistance regarding this matter would be much appreciated. I am being traumatized by these floors!!!!

if you have an epoxy, shellac or some other sealer you will probably need to scuff the surface with a fine grit sand paper(100 or above) to allow proper adhesion with the new paint you will be applying. just lightly scuff the surfacebe sure to remove ALL the dust that is created by sanding (a tack cloth is best). prime it if needed and then paint. good luck, hope this helps

Hi! Thanks so much for that information. I thought that I might have asked a really stupid question with such an obvious answer that no one would be interested in responding. So, in the meantime, I actually called a technical division of one of the major paint companies and talked with a concrete floor paint specialist! He advised me similarly, so I will be lightly sanding the floor to be followed by a good vacuum and wet cleaning with a household solution. Once the floor dries I will prime it with an interior enamel undercoater and then paint it with an epoxy-fortified concrete floor paint. Just another one of those weekend warrior jobs! Thanks again for your assistance.
