I need help, TODAY!There are trace amounts of black mastic (thin set. asphalt based) left on my basement floor from the removal of vinyl tile. I was able to get most of it off with diamond blade grinders. After that I cleaned/degreaser the floors many times over and then etched.Will I have a problem with epoxy or paint adhering to the surface? via /r/DIY http://ift.tt/2q6MEov
