    Brick Sealer Penetrating Water Repellent Protection For Bricks

    The best brick sealer for vertical and horizontal brick surfaces.

    Protect, restore, and extend the life of your home with Rainguard Water Sealers Premium Brick 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 bricks from freeze / thaw damage
    • Protects bricks from salt infiltration from 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 Brick 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.

    Where To Use

    Perfect for interior or exterior use on brick floors, chimneys, walkways, fences, walls, garden fences, and any other porous brick surfaces.

    Can I use this on painted brick?

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

    Can I paint over Brick Sealer at a later time?

    Yes. You can paint over Brick 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.

    What is freeze / thaw damage?
