We have found that most two-part water based paints and primers will work well over System Three epoxies. This includes acrylic and latex paints. We usually caution oil based or alkyd enamels and primers because they can contain driers that would react with the amines in our epoxies and can cause overall drying issues. Nonetheless, ALL paints should be tested by the user in a small area to ensure the results meets their expectations.
Surface Preparation: Allow the epoxy to reach full cure before applying paint. Sand the surface of the epoxy with 150-220 grit and then wipe clean with denatured alcohol.
