  • Our take on the RV Waterproof Sealant

    A 4.41 lb (2000 g) water-based sealant that cures to a clear, flexible waterproof membrane for RV roofs, gutters, windows, walls and other surfaces. It bonds to wood, concrete, brick, metal, ceramic and tile, and one container covers up to 160 sq ft at 1/12 inch thickness. The clear finish hides repairs and lets it move with thermal expansion instead of cracking. It suits RV owners doing a full roof coat and homeowners sealing gutters or window seams, and it competes with solvent-based rubber coatings on low odor and easy water cleanup rather than on heavy build.

    About the RV Waterproof Sealant

    This is a 4.41 lb (2000 g) water-based waterproof sealant for RV roofs, gutters, windows, walls and other surfaces. One container covers up to 160 square feet at 1/12" thickness. It cures to a clear, transparent waterproof membrane.

    The formula stays flexible, so it moves with the surface and accommodates thermal expansion without cracking or peeling. It is low-odor and withstands high and low temperature extremes. It bonds to RV roofs, wood, concrete, brick, metal, ceramic, tiles and more.

    To apply, clean the surface and remove loose debris. Apply the sealant with the included brush, a roller, or by pouring, and press it firmly into gaps. Apply in sunny, dry weather above 5°C/41°F. After 24 hours, a second cross-coat can be applied for maximum waterproofing.

    Questions and answers

    How much area does one container cover?
    Up to 160 square feet at 1/12 inch thickness. A full RV roof usually fits in one container; thicker coats or rough surfaces use more.
    Does it dry clear?
    Yes. It cures to a transparent membrane, so seams and repairs stay visible only as a slight sheen rather than a white stripe.
    Can it be used on a rubber RV roof?
    It bonds to metal, wood, concrete, brick, ceramic and tile. On EPDM or TPO rubber, check the roof maker's guidance first, since some flexible membranes are not compatible with water-based coatings.
    How long does it take to cure?
    Water-based sealants skin over in a few hours and fully cure over about a day in warm, dry weather. Rain or heavy dew before curing can wash a fresh coat.
    Can I apply it over an existing coating?
    Yes, if the old coating is sound, clean and dry. Loose or chalky material should be removed first so the new membrane bonds to the surface.
    What is in the box?
    One 4.41 lb (2000 g) container of sealant and an applicator brush.
    Where is the RV Waterproof Sealant cheapest?
    At Amazon, for $28.99, 57% under what the other stores charge, as of our latest check.
    What do buyers say about the RV Waterproof Sealant?
    Rated 5 out of 5 from 3 ratings.
