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!

If youre looking for great adherence and seal performance then this stuff fabulous, but the backing material that gets peeled off is so slippery and slick that it makes application really difficult for one person to do especially if youre standing on a ladder and very limited in reach to keep it in a straight line so it doesnt fold up onto itself as youre laying it down. Recommend two people - one to pull on the backing and the other the lay it flat and straight.

I used 450 feet to cover every top layer on my joists on my last deck job. Perfect! Good adhesion even at 50 degrees.

My new project with this extra protection will sully outlast the weather better then the structure that was replaced with this product on it. Easy to use, cuts easy with a razor knife.

Well, this joist tape is sticky. It is black and it is thick. Easy to peal and apply. It is super sticky so it stays where it is put, and is hard to remove once it is set. I used this to cover the top edge of the 30 year old beams and joists when I replaced the decking boards on my deck. Will it work? Will it prevent rot? It seems like a good idea. I will never know. By the time that the deck boards are removed years from now I likely will not be here to find out. Others have noted that they found it hard to cut. I have some advise. Do not use a knife. Scissors work best. It took some practice but I found that I had to cut steady and slowly so as not to cause the tape to separate from the plastic backing. If you get any of the sticky goo on your scissors, you are done and need to clean the scissors before cutting again. I used a clean rag and some carb cleaner to refresh my scissors when they got gummed up.

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.

I used this tape on our deck renovation to protect the joists from water damage. Great product!

This was very easy to use. It came very quickly. I used it under my Trex decking, on top of the wood frame joists

Easy to apply with good adhesion.

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.
