    Wood Sealer Penetrating Water Repellent Protection For Wood

    The best wood sealer for vertical and horizontal wood surfaces.

    Protect, restore, and extend the life of your home with Rainguard Water Sealers Premium Wood 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
    • Allows wood to grey naturally over time
    • Stain resistant to oil, gas, and anti-freeze
    • Great winterizing agent – Protects wood from freeze / thaw damage
    • Protects wood 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 Wood 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 wood?

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

    Can I paint over Wood Sealer at a later time?

    Yes. You can paint over Wood 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.
