Natural Look Concrete Driveway, Patio and Sidewalk Water Repellent

A-Tech Concrete Sealer is a low VOC (volatile organic compound) water-based silane/siloxane concrete water repellent that seals concrete driveways, sidewalks and patios from water penetration. This environmentally friendly concrete sealer protects your investment from the damages of de-icing salt and freeze thaw cycles.

Natural Look Concrete Sealer

A-Tech Concrete Sealer silane/siloxane concrete water repellent is a breathable 100% vapor permeable sealer. Application can be performed by sprayer, brush or roller. The sealer penetrates below the concrete surface. The concrete will look the same as if it where untreated. The texture and traction of the concrete is maintained. Once cured A-Tech Concrete Sealer will make the concrete repel water, reduce staining, reduce spalling and protect concrete from de-icing salt attack.

There is no surface film, gloss or sheen to the finished product.

100% Vapor Permeable

A-Tech Concrete Sealer is 100% breathable and allows water vapor to escape. Liquid water that hits the surface from rain stays out of the concrete. But water that is absorbed from under or behind the substrate, such as from the soil below concrete driveways or sidewalks, will not be trapped inside. This will reduce the efflorescence, spalling and scaling that can occur from water being trapped inside the concrete substrate and freezing during cold weather.

Siloxane Advantages

Chemically Bond to the Substrate

Siloxane based concrete sealers that penetrate into the substrate have many advantages over surface sealers such as acrylics, silicone and epoxies. The siloxane bonds chemically to the pores inside and below the surface of concrete substrates. This keeps liquid water from entering into the concrete. Also, since the sealer pentrates deeply, UV rays cannot degrade the concrete sealer. The penetrating sealer is below the concrete surface so it will give a long life.

Excellent for High Traffic Areas

Penetrating below the surface means that high traffic areas like driveways and sidewalks will not lose protection from high use. Surface sealers remain on top of the substrate and are eroded from repeated use. Also the substrate will maintain its natural texture and sheen.

Stopping Efflorescence and Staining

Efflorescence is the white color that is seen on many concrete buildings. This is the natural salts that are carried to the surface of the concrete by water vapor inside of it. Once the water gets to the surface, the water evaporates and leaves the salts behind on the brick surface. By stopping the water from getting into and penetrating the concrete, the efflorescence will be stopped. Also, because the pores of the concrete are filled, staining of the concrete will be greatly reduced.

Prevent Concrete Spalling and Scaling

Penetrating siloxane concrete sealers also allow interior water vapor to leave the concrete substrate. This is an important difference between a surface sealer and many other penetrants. A surface sealer will keep interior water vapor that needs to escape inside the brick. In a cold climate, water vapor trapped behind a surface sealer will freeze and cause the concrete to spall or scale (flake.) Siloxane penetrants reduce spalling or flaking because the water vapor can breathe to the air.

Protection from De-icing Salts

Water that penetrates into concrete expands when it freezes. This increases the water’s volume and causes the concrete to weaken and be physically broken. Repeated cycles can cause the concrete to begin to spall and flake. Concrete that is not sealed and has de-icing salts applied to melt ice can subject the concrete to many more freeze thaw cycles. That is becuase when the temperature drops below the effective working temperature of the de-icing salt, it refreezes and expands. By sealing concrete with A-Tech Concrete Sealer, the concrete will be protected from all of these cycles
