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

My contractor claimed this product was the best he ever used!

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

Ive tested this product for 8 years in harsh, outdoor weather extremes and it holds up fantastic. The glue does not dry, remains waterproof, and is almost impossible to remove later. Acetone has trouble dissolving the glue so dont expect this tape to come off if applied to a clean, oil free, and dry surface. I reordered 8 years later and the product seems the same. Dont change a thing, thanks!

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.

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!

Worked as advertised. Very sticky and adhered to the joist on my new deck easily.

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.

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.

Great adhesion. Very sticky. Recommended.
