Color:Coffee Achieve better results with Pro-Etch Professional Grade Concrete Acid Stains. A simple and easy to use product that achieves the look of Marble, Leather or Expensive Stone at a fraction of the cost of traditional flooring and surfaces. Reacting with the minerals already present in your concrete, which were randomly dispersed when the concrete was poured, acid stain beautifully achieves natural color variances, highs and lows, darks and lights, marbling and mottling, with unique character effect. With 15 colors to choose from your sure to find a color or color combo to compliment your surroundings. The 2 coat process ensures optimum saturation and coverage while giving you more control over darkness, tone, highs, lows and mottling, marbeling and highlighting effect. All with no mixing required. NOTE: Final Color is Determined by Your Particular Piece of Concrete. As each piece of concrete is different and unique, each piece of concrete will color differently. So a small test spot prior to doing the entire area is strongly suggested. Also, rougher, older, sanded and grinded concrete will reduce coverage.
