Painting brick, block, stone or mortar is rarely a good idea. While paint certainly changes the color of masonry, many compromises are made in terms of 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 just a few years. Brick, block, and stone have naturally porous surfaces that need to remain permeable. Our Stayntech® brick stains are absorbed by masonry, resulting in a finish that looks entirely natural as they maintain original color variations and varying surface textures.
