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

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.

So far so good, cheaper price than other comparable flashing tapes. Will buy more

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.

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’m no deck building master. I can only compare this to the Tr*x tape I bought for the doubled beams. To me this tape was better than the Tre* tape. It adhered good and was easy to work with. Just like all the other tapes don’t lay it on anything dirty. The sides of the rolls are sticky and will pick up any dirt it touched.

love the tape works GREAT sticks good.

Great product, half the price that I found at other places. I used it on my deck I just built. If it will protect and save joist rot for even 1-3 years its totally worth it. If youre going to spend thousands on a deck, its highly recommended to add just $50-100 for a protective product like this. Highly recommended.

Ive used a couple different products when building decks - THIS IS THE BEST FOR MY MONEY!! This adheres to the joists better than any product Ive used. I live in Utah - so we usually have a dry climate, but this summer has been the 2nd wettest on the record books, and the wood, tape, deck all look great. There isnt any white lettering on the tape, so you dont see little bits of white when you look down at your deck ... just the deck boards / composite boards and the blackness behind the decking

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

Super sticky black tape. Need a blade to cut it. Pain in the behind if need to remove it. Stops the water.
