A-Tech Concrete Sealer is a water-based emulsion of siloxane/alkylaloxysilane that penetrates below the surface of the concrete to seal it against water penetration.  The siloxane reacts with the concrete to fill the microscopic pores inside it to form a hydrophobic barrier against water.  The concrete will be sealed against water and resist spalling, staining and efflorescence.

De-Icing Salt Protection for Concrete Driveways and Sidewalks

A-Tech Concrete Sealer 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 concrete  reduces salt uptake and helps ensure that your own concrete driveway, sidewalk or patio will be protected from spalling caused by deicing salts.

Breathable Protection

A-Tech Concrete Sealer is 100% breathable which will allow any water inside the concrete to evaporate out of it.  This greatly reduces the concrete's chances of spalling.  Water that is trapped in the concrete can expand upon freezing and cause the concrete to spall.

Clear Non-Gloss Finish

Because A-Tech Concrete Sealer is a penetrant, the concrete surface will not darken or have a wet, shiny finish.  The natural texture and and traction of the concrete is maintained.

Penetrating sealer leaves no surface film to wear away and maintains surface texture.

1. 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.

2. 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.

3. 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.

4. 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 will not allow spalling or flaking because the water vapor can breathe to the air. 

5. 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
