BRICKFORM ARTesian stains are penetrating, water based stains that produce unique color effects in finished cementitious surfaces that simulate the natural shadings and aged appearance of stone or masonry. ARTesian Stain may be applied over smooth troweled or textured concrete, cement-based overlayments, vertical or horizontal concrete and masonry surfaces, artificial rock displays, water features and themed finishes. The color effect produced is unique to each stained surface and cannot be duplicated with other materials. ARTesian Stain contains no acids or harmful chemicals and works as an alternative to typical reactive acid stains. There are no acids or harmful chemicals integrated in its design.
