Whether you want the rich terracotta coloring of an Italian villa or the colors of natural slate, this is where that magic happens! We usually avoid applying color evenly because it makes for an awkward, fabricated look, which most people don’t want. Instead, we toss color powders onto the concrete. The powders chemically bond with the concrete and permanently stains it. No superfluous paint here! As the concrete dries, natural patterns form and that prepares the concrete for the next step.
