    Stucco Sealer Penetrating Water Repellent Protection For Stucco

    The best stucco sealer for vertical stucco surfaces.

    Protect, restore, and extend the life of your home with Rainguard Water Sealers Premium Stucco 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 change in texture or appearance.

    • Penetrating formula dries invisible
    • Prevents growth of mold and mildew
    • Stain resistant to oil, gas, and anti-freeze
    • Will not yellow, crack, or peel – even in direct sunlight
    • Great winterizing agent – Protects stucco from freeze / thaw damage
    • Protects stucco from salt infiltration from salts in the air (i.e. from the ocean)*

    *Looking for superior salt protection? Try Salt Guard.

    What makes Stucco 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.

    Yes. You can use this on color integrated stucco.

    Can I paint over Stucco Sealer at a later time?

    Yes. You can paint over Stucco 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.
