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

This was very easy to use. It came very quickly. I used it under my Trex decking, on top of the wood frame joists

A much thinner product versus several others that are on the market for Use, One and done send it back In price comparison this is not a good buy.

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

super sticky and seems to do the job very well. Guess I wont know for years if its properly protecting my deck joists, but it looks promising. I know when I back out some screws they were covered in the sealing material, so that seems good.

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.

This joist tape was readily available when Home Deport version was back ordered. But the adhesive is gooey and got all over my hands during application. I had to clean my hands with paint solvent twice during application.

Use IMUS SEAL before applying deck boards. Whether you’re using wood or composite (eg TREX) sealing the top of the supporting joists is a must. This product exceeded expectations. I applied a week before I could install my TREX boards. Despite several rain storms it remained in place to complete the project. I used TREX screw connectors and they were compatible and made the job easy. I’m confident that this project will add years to the life of the support structure.

Im redoing and outside deck. The joists are still ok but...Ive used this on other decks and it is great at preventing water from rain/snow from entering the joist via screw or nail holes. You will be thankful you used this stuff down the road.

The idea is nice, however it is better and cheaper actually to go with silicone or rubber paint, you can paint all the joints including the top (for example this https://www.amazon.com/Liquid-Rubber-Roof-Coating-Sealant/dp/B01EM9GAA8/ref=sr_1_5?dchild=1&keywords=silicone%2Broof%2Bpaint&qid=1634698430&sr=8-5&th=1) for this price. I used them so cannot return

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
