LLPT Butyl Seal Putty Tape BST342 - 2 Pack, 3mm x 19mm x 10m Black

LLPT Butyl Seal Putty Tape is a heavy-duty, self-adhesive solution designed for both indoor and outdoor leak protection. The black, 3 mm thick tape creates a waterproof barrier that seals windows, doors, RV roofs, EPDM roofing, and a wide range of other surfaces, keeping moisture, wind, and dust out of your living spaces. Its flexible composition conforms to tight corners, unusual curves, and jagged edges, allowing you to achieve a reliable seal on glass, fiberglass, wood, metal, plastic, and rubber without gaps. Once applied, the tape can be painted over, giving you a seamless finish that blends with surrounding materials while maintaining the strength of a professional repair. Each roll measures 19 mm wide and 10 m long, providing ample coverage for multiple projects, and the convenient 2-pack ensures you always have a spare when unexpected leaks appear. Whether you are fixing a boat window, patching an RV roof, or reinforcing a home door frame, LLPT Butyl Seal Putty Tape delivers lasting, weather-resistant protection you can trust.
