What are the best water repellent sealers?
If you are looking to apply a penetrating water repellent sealer we recommend choosing a silane/siloxane blend. Silane/Silixane blended concrete sealers not only penetrate concrete substrates providing concrete protection from the inside out but they chemically bond keeping water from entering the concrete. Since a Silane/Siloxane blended sealer is also a penetrating sealer driveways, sidewalks and high traffic areas will be unaffected and will not lose protection. After sealing, the concrete will stay in its natural state with no added sheen or texture. Water will be repelled and bead from the surface and concrete will be protected from water damage. Added bonuses are protection from: efflorescence, staining, spalling, scaling and deicing salts; it is considered a breathable sealer allowing water vapor to leave the slab. We recommend a Silane/Siloxane blended sealer for all concrete based surfaces especially concrete blocks, pavers, stucco, brick, clay tile, exposed aggregate, sandstone and slate. Since Silane/Siloxane sealers are blended sealers you get the benefits of two different products in one formula. Keep in mind even though they are penetrating sealers Silane/Siloxane blends are too topical in nature to be used in conjunction with a topical sealer such as an acrylic.
