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

Don’t let it touch nothing it’s not going to stick permanently to

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

If youre looking for great adherence and seal performance then this stuff fabulous, but the backing material that gets peeled off is so slippery and slick that it makes application really difficult for one person to do especially if youre standing on a ladder and very limited in reach to keep it in a straight line so it doesnt fold up onto itself as youre laying it down. Recommend two people - one to pull on the backing and the other the lay it flat and straight.

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

The adhesive side of this acts more like caulk than duct tape. Very good adhesive after it sat in the sun for a few hours. My only problem was it would easily fall off the cardboard center tube if you werent careful.

As expected, shipping wasn’t as fast as expected but the product arrived and works as intended. Great product !!!

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 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.

I recently replaced a redwood deck with a Brazilian hard wood. I noticed joist decay was primarily due to moisture in the gaps between the deck boards. After replaced and repair the joists, I applied this product. I am confident this will extend the life of the joists and deck board. Easily applied and great adhesion.

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.
