For the best color results, check your acid stain activation times before stain application. The first and final appearance of acid stain color changes dramatically, and different colors have very different activation ranges.
As the acid stain dries and processes, a residue of alkali and minerals forms on the surface of the concrete. This is completely normal and is part of the reaction process. Each stain has different activation times to fully color the concrete, generally from 4 to 8 hours. Acid stain can be left on the surface longer if desired.
