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

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

Tape workout very well would definitely us it on my next project.

Adhesive is very good on dry wood. Don’t expect it to stick to pressure treated lumber that is still wet.

I have used this in the past around a pool deck. It was quite sticky and was not a problem using as long as you remove the backing as you go. I recently used it again rebuilding a deck under a hot tub. It seems that bromine used in hot tubs will cause treated wood to break down and rot. After five years I had to replace the deck so I now have composite decking on top with this tape to protect the joist below.i feel confident using this tape will stop any rot below the decking. Although its not inexpensive, I recommend using this product.

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.

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

Adheres well but pricey

Great product to use with composite decking!

We put the tape down but didnt get it finished. The adhesive is great and fits snug on the boards. It was easy to do and I think it will be a great thing to keep the deck in good condition. I wanted to go ahead and review the tape because I dont see any problems in the future.

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.
