Additional Details

Weather-Sil & Weather-Sil Extreme are water-based penetrating silane sealers that penetrate deep into concrete where they chemically react to form a hydrophobic barrier, preventing the absorption of water and chloride ion-containing deicing salts. Surfaces sealed with these products are more resistant to the damaging effects of freeze/thaw and deicing/road salt damage including surface scaling, spalling and delaminations. Weather-Sil & Weather-Sil Extreme protect and extend the life of concrete driveways and garage floor surfaces.

Weather-Sil & Weather-Sil Extreme are safe and easy to use. Their single-component formulation are very low odor and have a high flash point (>212° F/100° C).

Recommended Applications for these penetrating silane sealers

• All exterior, vertical or horizontal cast-in-place or precast concrete

• Concrete pavers and landscape blocks

• Exposed aggregate

• Can be applied to both new (over 28 days old) and existing concrete surfaces

• Tightly-finished, troweled substrates (garage floors) = 250-300 ft²/gal (single coat)

• Broom or open-finished, porous substrates (driveways and sidewalks) = 150-200 ft²/gal (single coat)

Advantages of Weather-Sil & Weather-Sil Extreme

• Simple, DIY application

• Safe and easy to use with very low odor

• Protects concrete driveways and garage floors from damaging effects of water, ice and deicing salts

• Protects against delamination from corrosion of embedded reinforcing steel

• Minimizes freeze/thaw-related scaling and spalling

• Colorless and non-yellowing – does not change natural appearance of concrete

• Allows treated surfaces to breathe naturally, minimizing surface sweating

• Penetrates deep into concrete surfaces and significantly outlasts other types of surface coatings that fail due to abrasion and oxidation

• Significantly reduces maintenance costs

• Environmentally-friendly – active component goes into the concrete, not the atmosphere

• Extended warranties are available for up to 5 years
