    Concrete Sealer Penetrating Water Repellent Protection For Concrete

    The best concrete sealer for vertical and horizontal concrete surfaces.

    Protect, restore, and extend the life of your home with Rainguard Water Sealers Premium Concrete Sealer. This sealer is formulated with a water-based silane and siloxane blend to provide superior protection against wind-driven rain, mold, mildew, and other moisture damage. The penetrating formula means no film is created and the surface will not become any more or less slippery than it already is.

    • Penetrating formula dries invisible
    • Prevents growth of mold and mildew
    • Stain resistant to oil, gas, and anti-freeze
    • Great winterizing agent – Protects concrete from freeze / thaw damage
    • Protects concrete from salt infiltration and ice melting salts and de-icers as well as salts in the air (i.e. from the ocean)*

    *Looking for superior salt protection? Try Salt Guard.

    What makes Concrete Sealer different? A proprietary ingredient called Micro-Lok™. This additive ensures the absorption of the sealer into the surface and creates a long-lasting hydrophobic barrier that is not affected by weathering, salt, dirt, freezing temperatures, UV light, and wind-driven rain, among many other damaging elements.

    Can I use this on painted concrete?

    No. You will want to use Paint Sealer on your painted concrete.

    Can I paint over Concrete Sealer at a later time?

    Yes. You can paint over Concrete Sealer but keep in mind it will not protect the paint from moisture damage. You may want to use Paint Sealer after the surface is painted and fully dry to protect the paint from moisture damage.

    How soon after laying down fresh concrete do I need to wait before sealing it?

    You will need to wait at least 48 hours at 75°F for the concrete to be completely dry before applying Concrete Sealer.
