Advantages:
A-Tech Masonry & Brick Sealer is a silane/siloxane water repellent that prevents water penetration through masonry and concrete substrates according to ASTM-514 for 10% siloxane content at simulated driven rain at 62.5 mph. Any masonry substrate such as brick, or stone can be made water repellent using A-Tech Masonry & Brick Sealer.
A-Tech Masonry & Brick Sealer water repellent meets the National Cooperative Highway Research Program (NCHRP) Report 244 for the reduction of chloride ion (salt) content in concrete roadways caused by wintertime deicing salt application. Sealing the brick used for pavers in patios or sidewalks reduces salt uptake and helps ensure that your own brick driveway, sidewalk will be protected from spalling caused by deicing salts.
A-Tech Masonry & Brick Sealer is a water-based emulsion of siloxane and alkylaloxysilane. It penetrates into the substrate to form a waterproof hydrophobic barrier against water penetration. Upon penetrating into the substrate of the masonry or brick, it chemically bonds and fills the pores below the surface. The masonry or brick will be waterproof and protected from spalling, staining and mold and mildew growth.
However, A-Tech Masonry & Brick Sealer is 100% breathable and allows water vapor to escape. This means that the liquid water that can be absorbed from under or behind the substrate, such as from below brick driveways or sidewalks, will not be trapped inside. This will reduce the spalling and scaling that can occur from water being trapped inside the brick substrate and freezing during cold weather.
Because A-Tech Masonry & Brick Sealer penetrates below the surface of the brick the appearance will not change. Also, the original texture, feel and traction of the surface is maintained.
