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

Used this to cover the 2x8 beams under a deck I was building. Very nicely thick and super sticky! Works perfectly to protect the wood. Highly recommend!

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

I used black Ipe Clips to fasten down my deck, and this tape makes the clips effectively disappear. The adhesion is incredible - highly recommend.

I used this on top of the joists while building my deck. This will keep out bugs and moisture to make your deck last longer.

Easy to use, super sticky, and a great value. Bought 5 for my main deck, buying more for the extension and stairs

Great adhesion. Very sticky. Recommended.

This tape is better than described. I applied it to the tops of my joists and stair stringers (glossy black strips in the photo). I wish Id know about it 10 years ago otherwise Id not be replacing my stringers. The tape withstands several step-board on and offs to install railing posts and the tape will not ride up the screws. If youre looking to extend the life of your exposed decking support structures this stuff is easy to work with.

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

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

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.
