So I finally painted the garage floor with one of those DIY kits. I cleaned the HECK out of the floor, etched it twice, and followed the directions on the kit when laying it down. As it dries I can see NOTICABLE differences in color/gloss... I have no idea what I did worng? ANyoen else have this happen? Can I paint ontop the epoxy or do I need to scrap it off and start over?
