    Ziollo

    Ziollo RV Roof Lap Sealant - Self-Leveling EPDM Caulk for Rubber Roofs, Seams & Vents - Waterproof Sealant for Motorhomes, Trailers & Campers - White, 4-10 oz Tubes

    9.3 worth the money
    9.3 Simple to use
    Main highlights
    • SO EASY YOUR DOG COULD DO IT — Almost. Our self-leveling roof sealant flows smoothly into seams and around fixtures, doing half the work for you. Clean, cut, apply, done—then grab a cold one. Even if you think "caulk gun" sounds like a water toy, you'll get professional-looking results. That's why we're the best sealant for RV exterior seam repairs
    • SEAMS SEALED, WORRIES GONE — While you're roasting marshmallows, our self-leveling RV caulking lap sealant is working overtime on those pesky roof seams and vents. Unlike ordinary camper roof sealant, ours stays flexible from scorching desert heat to frosty mountain mornings. Because nobody wants to play "find that drip" at 2 a.m
    • SAFE FOR THE WHOLE CREW — Our caulking sealant formula is non-hazardous with no solvents. Unlike sketchy silicone roof sealant options, ours won't make you evacuate the campsite. Safe around kids, pets, and your morning coffee. Because your weekend getaway shouldn't require a hazmat suit
    • OUTLASTS THE TOUGHEST Conditions — Other lap sealant for RV roofs products make you reapply yearly (fun, right?). Meanwhile, our RV Roof Lap Sealant keeps its grip and flexibility for the long haul. We've engineered it to withstand UV exposure, temperature swings, and all the bumps of the road, so you can spend more time exploring and less time maintaining
    • ONE TUBE DOES THE TRICK — Each 10oz tube covers 25 linear feet of adventure protection. Our self-leveling RV roof sealant flows right where you need it—around vents, along edges, and into seams. Sticks like crazy to EPDM rubber roof, TPO, metal, wood, and fiberglass without the complicated prep work. That's more time for campfire stories
