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

So used this for my first deck project in a long while. I’ve seen a lot of people using these and want to try it out. Seems for the couple bucks why not make it last longer. Obv I can’t give a did it work review. But here are my thoughts….. Install was not to hard. Very sticky so cloth gloves helped. Two people really makes a job go fast. We rolled all our tape as recommended by zip tape but this manufacturer does not suggest it. If you messed up you could pull back and fix. We used it in really hot weather so I think that made install easy. The small rolls had not trouble with install or the paper. The big roll had troubles with the paper backing. I like seeing the black in the joist spacing. Other than that it seems to be s good idea to protect the structure. I’d give it a good review but can’t give 4 or 5 star since ultimately you want to review performance as well.

Tape workout very well would definitely us it on my next project.

Ive seen a number of questions and comments about the tapes specs, so here goes. THICKNESS: using a micrometer, the thickness of the tape + backing paper is 0.023 thick, and the paper backing is 0.002 thick, which means that THE TAPE ITSELF IS 0.021 THICK. The butyl tape seems to be of good quality but I cant tell you how long it will last when exposed to the elements. Is it gooey? Yes. I have no way to measure gooey, but I had occasion to put some of it down on a girder, then two weeks later I changed my mind about the joists that would go over it. I then removed the tape and thought you might like to see what it looks like as you peel the tape away. See photos. When the tape came off, it left a lot of this glue on the wood. I used the removed tape as a way to lift off the goo, much as one wraps Scotch tape around your hand, sticky side out, and then use it as a lint brush. Thats what I did except I didnt wrap the discarded tape around my hand ... too messy. I eventually got most of the glue off of the wood, but there is still a bit left. I can therefore attest to the fact that THIS STUFF IS GOOEY and will probably do a good job of preventing moisture from getting past it and into the wood that it protects, which is its main job.

I used this Butyl tape on the tops of the joists on my new deck... It was easy to use, and will add years to my deck. Would recommend.

super sticky and seems to do the job very well. Guess I wont know for years if its properly protecting my deck joists, but it looks promising. I know when I back out some screws they were covered in the sealing material, so that seems good.

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

Very easy to apply. Sticks well and until you press it firmly in place you can usually reposition it. I dont have any concerns with the tape and recently bought 2 more rolls for the next phase of my deck. After 3 months in the Texas heat, the tape is holding up well.... of course its way too early to rate the durability.

I recently replaced a redwood deck with a Brazilian hard wood. I noticed joist decay was primarily due to moisture in the gaps between the deck boards. After replaced and repair the joists, I applied this product. I am confident this will extend the life of the joists and deck board. Easily applied and great adhesion.

Works great, sticks well to deck joists, easy to apply, good price! Highly recommend.

Bought 6 rolls of this tape. Easy to apply, very sticky and stays put. It’s a close fit to a joist which is 1.5 inches so there’s not a lot of wiggle room. But does what it’s supposed to do. Much cheaper than the big name brand items and for what it does, you’ll never know the difference.
