Joist Butyl Tape Review

My company, 5th Gear Decks & Exteriors, specializes in building composite decks. We have used this tape on a couple of decks recently and just loved the product. It was easy to use, and got the job done, and done well. The customer service from First Adhesive Technologies was also amazing. Will be using this tape in the future and I would highly recommend others to as well!!
