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

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.

Worked well. Much less expensive than other brands.

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.

Great value Way cheaper than home depot

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.

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

Easy to apply with good adhesion.

My original intention for this was as a moisture barrier between my new exterior deck stairway stringers and the Trex deck boards I also used on my stairs, and I discovered another bonus in the process. On some of the other deck joists where I used a copper brown wood preservative on the cut surfaces, and where those surfaces directly contacted the underside of the Trex composite boards, the wood preservative leached up into the boards and significantly discolored them! Wherever I used this tape, that leaching and discoloration did not occur. Its a bit pricey, but not a bad idea to use on top of all joists and stringers!

I used this tape on our deck renovation to protect the joists from water damage. Great product!

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.
