Imus Seal Butyl Joist Tape for Flashing Deck Joists and Beams (1-5/8” x 50’ Non-Skid)

Great product to use with composite decking!

The idea is nice, however it is better and cheaper actually to go with silicone or rubber paint, you can paint all the joints including the top (for example this https://www.amazon.com/Liquid-Rubber-Roof-Coating-Sealant/dp/B01EM9GAA8/ref=sr_1_5?dchild=1&keywords=silicone%2Broof%2Bpaint&qid=1634698430&sr=8-5&th=1) for this price. I used them so cannot return

Knowing there was the concept of there being joist tape most influences my rating. For the minimal cost, an almost guaranteed way to prevent the most common way your deck joists are going to rot seems like it should be a requirement of any deck build. The people that built my deck did not use it and that seems criminal unless this concept did not exist 10 years ago. As far as this particular product, it did exactly what I wanted, seemed to be good quality, adhered well. It is like slightly wider electrical tape with some roughness on the side where the deck boards would sit. I would use this product again next time I need it.

I refinished my existing deck with Trex. This product was fantastic. Listened to the other reviewers that suggested to keep it in the freezer - much easier to work with. The adhesive is super sticky! Got the job done at a better value than the “name brand”. Also impossible to don in Big Blue/Orange.

Super sticky black tape. Need a blade to cut it. Pain in the behind if need to remove it. Stops the water.

It is an excellent deck tape. I have nothing to envy to those of much more expensive brands, it worked great wonders.

This tape worked so well that I had to order more to complete our deck. It even got wet from rain before we put the deck boards down and it didnt move at all. Very sticky but works great. Would definitely recommend.

We replaced our deck and kept the existing joists. To extend the life of the joists we lined them with this tape. It was easy to use, and had great adhesive.

Adhesive is very good on dry wood. Don’t expect it to stick to pressure treated lumber that is still wet.

It is the same product as a name brand at greater cost. You should use it to cover deck joists where deck boards will rest, and I used it as well to cover deck screws holding the frame together. By the way I recommend (and did so) to caulk every other wood penetration event though I used treated wood. Overkill costs little but I do not want to ever replace rotten wood. I used composite deck boards and expect the deck to last 25 years.
