Heat Seal Tape restores waterproof integrity to the seams of jackets, tents, rucksacks, and other outdoor gear that take a battering in wet conditions. This self-adhesive tape bonds to fabric seams using heat application, replacing worn or failed factory tape and creating a durable, flexible waterproof seal. Simply remove any old tape, position the new tape over the seam, apply heat with an iron or heat gun, press firmly, and allow to cool completely for a secure hold. The tape maintains its flexibility after curing, so it won't crack or peel when fabric stretches or flexes during use - suitable for active outdoor kit. At 1 metre in length, it's the right size for patching individual seams or smaller repair jobs on jackets, trousers, tent panels, dry bags, and similar gear. Works on nylon, polyester, and other common outdoor fabrics. Stormsure has manufactured flexible repair adhesives since 1992.
