Review on Imus Seal Butyl Joist Tape: Ultimate Waterproofing Solution for Flashing Deck Joists and Beams (1-5/8” x 50’) by Richard Summerall

This ribbon is better than described. I applied it to the top of my bars and stringers (black shiny streaks in the photo). I wish I had known that 10 years ago or I wouldn't have changed my strings. The tape will withstand multiple steps and stops to install railing posts and the tape will not pick up the screws. If you are looking to extend the life of your exposed decking support structures, this material is easy to work with.
