"Stained" concrete. I actually used the Behr Stained Concrete line, but in all reality it is semi-transparent paint. The beauty is that you don't need to use an acid. I'll warn you though, don't apply it using their method. It comes out pretty flat that way. Instead, I used a deck sprayer followed by a roller. I built up 6 layers of varying amounts and patterns to give it an acid etched look. Sealed with the luster top coat.
If I wanted a cool looking Hair Salon -- this would be uniquely Pink , but with style and the acrylic chairs tone down the power of the pink! The mirrors work well -- It's a win for me! COLOR DONE RIGHT!
