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

I have used this in the past around a pool deck. It was quite sticky and was not a problem using as long as you remove the backing as you go. I recently used it again rebuilding a deck under a hot tub. It seems that bromine used in hot tubs will cause treated wood to break down and rot. After five years I had to replace the deck so I now have composite decking on top with this tape to protect the joist below.i feel confident using this tape will stop any rot below the decking. Although its not inexpensive, I recommend using this product.

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 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.

Use IMUS SEAL before applying deck boards. Whether you’re using wood or composite (eg TREX) sealing the top of the supporting joists is a must. This product exceeded expectations. I applied a week before I could install my TREX boards. Despite several rain storms it remained in place to complete the project. I used TREX screw connectors and they were compatible and made the job easy. I’m confident that this project will add years to the life of the support structure.

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.

I used this product for deck joists and the ledger. Easy to apply and good adhesion.

Adheres well but pricey

Worked well. Much less expensive than other brands.

This was easy to apply. We put it on all of ours joists for a 26 foot long deck. Time I’ll tell if it helps the wood hold up. I only wish it was a little stickier.

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.
