    Some of the BEST Butyl/Joist Tape Available!!!
  

*by I***V on Reviewed in the United States on November 23, 2019*

Building a dock (saltwater) and needed the extra protection for the joists, as SW Florida can be brutal to wood (even marine grade pressure treated wood). Tried three different brands before landing on this one and let me tell you that I just don’t understand any of the reviews for this that say it doesn’t stick. Unfortunate that people who don’t think things through post negative reviews because I almost passed these up. So frustrating! Listen people, if it’s pealing up, YOU’RE DOING IT WRONG!!!!  Take a moment to wipe or brush off dust and dirt with a DRY cloth or broom. Seems crazy that I have to point out that dust and dirt will cause you problems. ALSO, the directions (yes, some of us actually read directions) state that prolonged direct contact to sun light can cause pealing. Guess what? Before I taped up the entire dock frame, I tested this tape on a couple of spots on the joists of my dock and let it sit in the bright Florida sunshine for three days with NO pealing. So it performed better than the manufacturer claimed. This is SUPERIOR joist/butyl tape out of the four major brands I tried. Here are some suggestions to get the best performance out of this tape. CLEAN THE SAW DUST AND DIRT OFF OF THE JOISTS WITH SOMETHING DRY BEFORE TAPING THEM. It doesn’t take much, just a little dusting. Then to be safe, TAPE SMALLER SECTIONS AT A TIME. DON’T tape off the entire deck/dock frame. Tape a section, put your decking down, then tape another section, then repeat. Even though I had no issues with pealing, this can ensure that your tape doesn’t get prolonged exposure to sun light as the manufacturer indicates could happen.

    Seems to be quality rubberized tape but with adhesion issues in cold
  

*by C***S on Reviewed in the United States on January 4, 2021*

Overall it works well to keep water away from your beams, though you may need staples to hold it in place on vertical surfaces or on edges if you want it to be a tight fit. For my purpose, I'm using it on a drop beam where the joists are resting on top of the tape. Tape is somewhat stuck to the beam on it's own, but isn't really stuck on the edges. It likely would stick better if I hadn't installed on a 40 degree day. I tried to run it on the vertical edge of the beam but it really isn't sticking well, will use staples there. This tape does work, the paper backing came off easily (some have complained this is an issue with other brands), and its protecting my beam, so I'm happy enough with it. Just would prefer the glue worked better at lower temperatures.
