Stained Concrete-concrete stain reacts with the minerals in concrete chemically, to form a permanent color that is durable, chip resistant and does not flake. Stained concrete colors can be mixed to create a multitude of color shades and intensity with new or old concrete surfaces. Acid stain is applied by brushing, rolling or sprayed onto the surface. Colors available, but not limited too are, violet, black, lime, browns, off white, terra cotta, blue, tan, sea blue, green and rust. To prep the project prior to staining concrete, the surface is sanded to remove any impurities and should be free of grease, oil, dust, paint and other materials. New concrete should be at least 28 day old before staining, After achieving the desired look and color, the stain is allowed to dry then neutralized, prior to sealing or waxing.
