MegaTape Waterproof Double-Sided Joint Sealing Tape

Available in 3 different lengths, Double MegaTape is a permanently flexible upstand and a first fix solution for forming a 100% waterproof seal between walls and bathroom and wetroom and kitchen units.

DMT’s unique self-adhesive bitumen strip on both sides of the tape means it adheres without needing any other adhesive. Double Mega Tape accommodates for vertical movement of up to 30mm while maintaining its waterproof seal making it ideal for all applications. The thin, flexible material means it fits tidily into corners and doesn’t kick out your tiles.
