100% WATERPROOF RUBBERIZED SEAL: Stop catastrophic leaks instantly. Our premium butyl adhesive forms a permanent, molecular-level bond on contact. It creates a watertight and airtight rubberized barrier that keeps water out of your home, vehicle, or above-ground pool, even under active water pressure.

Frequently Asked Questions: 8-Inch Waterproof Butyl Seal Tape (8" x 5')
Why should I use the 8-inch wide tape instead of the 4-inch tape? The massive 8-inch width is designed for catastrophic repairs. If you have a gaping hole in an RV roof, a wide split in an awning, or a large crack in a storage tank, the 8-inch tape allows you to cover the entire damaged area with one solid piece. This eliminates the risk of water seeping through the seams of overlapping thinner tapes.
Will this tape stick to an EPDM rubber RV roof? Yes. This tape features a highly aggressive butyl rubber adhesive that bonds perfectly to EPDM rubber roofs, fiberglass, aluminum, and vinyl. It is one of the most effective and permanent ways to seal a leaking camper roof or torn awning.
Can this tape stop an active water leak on a pipe or pool? Yes. The ultra-thick rubberized adhesive is specifically engineered to be 100% waterproof on contact. It can be applied to wet surfaces and instantly creates a tight, watertight seal that actually increases with pressure, making it excellent for patching above-ground pools and massive plumbing leaks.
Will this sealing tape melt in the summer heat or crack in the winter? No. This tape is designed for extreme, all-weather outdoor use. It remains fully active and securely bonded in freezing temperatures and easily handles intense, direct summer sun and heat without melting, drying out, or becoming brittle.
Can I remove this tape later if I need to make a permanent fiberglass repair? This tape is designed to be a heavy-duty, permanent patch. Because the butyl adhesive bonds at a molecular level to completely seal out water, it is extremely difficult to remove once fully cured. If removal is absolutely necessary, you will need to use a dedicated adhesive solvent and a heavy-duty scraper.
