I used Behr porch and floor paint (100% Acrylic) bought at the Orange Store throughout the house to faux a concrete stain look over old asbestos tile glue. It came out great! As I was moving furniture back into place, it scratched all of my hard work. I've searched the net and this site, but I'm not getting an answer on what type of clear coat to use to protect the paint. Does anyone have suggestions?
