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

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.

We used this when building the base of our deck. Great value. Easy to install on the wood beams.

Worked like a charm. Very simple to apply. Would purchase again.

Worked as expected. Slightly difficult to remove the backing from the adhesive side but nothing that would prevent me from buying again.

I recently installed about 800 feet of this on a very large deck we are having built in Florida. The previous all wood deck had rotted. Were replacing that deck with 25-year Trex and using ground contact lumber for the joists and framing. The previous frame had rotted from the top down, primarily associated with screw penetration used to attach the wooden decking. I wanted to give this deck as long a life as possible. Since its brand new, I dont really know if the joist tape will work for its intended purpose (sealing screw penetrations), so my rating is based on quality of product, ease of application, durability during the construction process, comments from our deck contractor, and cost compared to its main competitor sold by Trex. Its easy to apply, albeit youll sometimes get a bit of butyl on your hands. Just remove a bit of the protective film from one end and leave the tag end sticking out to the side, stick that end to a joist, line up and lay about 3-4 feet of tape on the joist, hold that end down with your thumb, reach back to the film and pull it down to your thumb and stick it, smooth the tape with your hand, and repeat. The contractors said it actually made laying the deck faster because the decking tended to stay in place as they were laying it, the plastic facing grabbed the hidden plastic fastener so it didnt move, and once installed, the black plastic fastener was hard to see against the black facing. The tape also held up remarkably well to being walked on and having boards dragged over it, though I did have to make a few repairs. Because of delays in getting our full order of Trex decking, the tape on part of the deck has been sitting exposed to rain and sun for several weeks and still looks great. Its about 30% less expensive than the competing brand, but I didnt use the competitor, so I cant compare quality. Also, the customer service was great. I underestimated the amount needed and the company owner made sure I received my reorder on time and at no additional cost.

Ive tested this product for 8 years in harsh, outdoor weather extremes and it holds up fantastic. The glue does not dry, remains waterproof, and is almost impossible to remove later. Acetone has trouble dissolving the glue so dont expect this tape to come off if applied to a clean, oil free, and dry surface. I reordered 8 years later and the product seems the same. Dont change a thing, thanks!

I made some joist repairs on my 900 sq ft deck. I made th repairs in early August. Based on other reviews I really hope this product extend the wood joist life by 3 - 4 yrs.

Useless. I purchased this to place on the tops of the joists and frame in a new backyard deck. This tape went on easily, but 1 day later, I noticed that it was starting to pull away from the wood. By day 2, it was only adhering in a few places. I had to remove it all before placing the top boards on my deck, and I replaced it from a brand purchased at Home Depot. The joist tape from Home Depot is far stronger and more adherent than this tape. DO NOT PURCHASE!

We put this on some joist before a storm and was a little afraid of that the wind would rip it off. But nope. It stayed right where we stuck it. We we not able to get the Azek on till a week later and it looks good as new. Recommended product.

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.
