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

It meet and exceeds all expectations, only issue all the rolls seemed run short measured several times to make sure I had enough for joist on my deck and was still about 4 feet short

Used the tape on an existing outdoor deck that I was replacing the boards on . As long as the joists are dry the tape sticks well , if they are wet doesnt stick well . I installed a few weeks ago so no idea on longevity but it looks like it should last a long time .

Tape stuck quite well and as easy to work with. I thought the length would be more than sufficient, but what with three stringers and all the other places I found to use it on, like railings, it was just enough.

As advertised. Great adhesion, just make sure your joists are dry and clean and this stuff will not come up. The butyl can settle to one side so the end of the roll gets a little messy but not bad. It would be nice if it was 1-3/4” or more but that’s today’s lumber not the tapes fault. It started raining before I finished but you can see the water bead up and run off

Extremely tacky. When I removed the deteriorating wood boards on my deck the joists had not been taped. Decided to tape before installing the new Trex. Sticks and sticks well even on weather materials.

Great adhesion. Very sticky. Recommended.

Easy install, rolled into joist for new outdoor deck. Appears to me the sealant/adhesive will seal around deck board nail or screws to prevent water penetration to joist.

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.

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

Great product to use with composite decking!
