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

I had old, but dry joists that were is excellent shape. So I plugged the old nail holes and any splits in the wood, and then laid down this joist tape. It worked great. The adhesive is so thick and sticky that I believe it will keep moisture out as well as sealing the new nails/screws penetrating the joists. The project needed 5 rolls of tape, so the cost for the tape was reasonable to protect the joists for another long period of time.

Very easy to use + strong adhesive = great for a DIY’er. Highly recommend it, my father has to redo his deck after 15 years and will use this product on his deck as well.

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

I am replacing my 20 year old treated decking with maintenance free decking and using the hidden clip fasteners. This product works well to cover the old holes and to just prevent water from sitting on the top of the boards. If you wipe off the boards first this does stick pretty well. Since it is black it also looks better in between the boards.

This product is excellent for protecting the would underneath our decking boards. But be prepared to get sticky hands

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.

Husband very happy with the functional and usability of the product. Bought a second time for another deck he is helping some friends with. Highly recommend.

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

Dislikes 0. Love this product. Makes my projects complete.

This product adheres well and has a nice rubberized feel. It is great to cover the run part of stringers before attaching the step board on deck stairs.
