Our 3" tape is designed for patching and repairing old, torn insulation, joining seams, sealing edges and anywhere else you need a good vapor barrier adhesive. Each roll is 3 inches wide by 180 feet long. Our tape is pressure-activated and does require firm pressure to adhere well and can take 30-45 days to fully cure to maximum adhesion. Our tapes have an aggressive adhesive for all temperature ranges that won’t come undone over time. BlueTex tape is constructed with a super-strong PET Film and has a bright white glossy finish. Also perfect for masking windows and doors for applying stucco. 30 days in outside weather with easy removal and no residue on frames.
