Painting brick, block, stone, or mortar is rarely a good idea. While paint certainly changes the color of masonry, many compromises are made regarding structural integrity, aesthetic appeal, and durability. Paint creates an impenetrable surface membrane that coats exterior masonry and prohibits moisture, vapors, and humidity from escaping—typically resulting in the paint blistering and peeling within a few years. Brick, block, and stone have naturally porous surfaces that must remain permeable. Our Stayntech® brick staining is absorbed by masonry, resulting in a finish that looks natural as it maintains original color variations and varying surface textures.
