BEHR advertises their Premium Protector and Waterproofer product as a silicone waterproofer to penetrate and keep water out while shielding against corrosion and salt damage. The Behr premium interior and exterior waterproofer claims to protect concrete for 10 years. It uses water based silicone technology designed to penetrate surfaces up to 1/2 inch. The waterproofer creates a barrier inside the surface that keeps water out but lets water vapors escape reducing corrosion, spalling, efflorescence and freeze-thaw damage. The protector and waterproofer can be used on horizontal and vertical uncoated concrete and masonry surfaces such as concrete block, pavers, stucco, brick, unglazed tiles, exposed aggregate, concrete, sandstone and slate. Before you apply Behr premium protector and waterproofer it is essential you have a properly cleaned surface. Apply until saturated by brush roller or garden sprayer to a dry surface.
