Great tape

Would Recommend

I have used this tape on several projects. Makes perfect since. If you keep water from sitting on wood, it’s going to last much longer. It’s the perfect width for 2x lumber. Easy to use, and Really sticks,

Great Idea

Would Recommend

Really looking forward to pulling up the current boards and using this tape to refinish our balcony deck. The 2x12 boards underneath are attached to the house so we have to protect any way we can. The adhesive strip is a plus

It worked for what we needed it for so glad too!

Would Recommend

Well my husband didn’t exactly use this for what it’s really used for but I tell you, good idea really worked! Our dryer house was heating up the enclosure where our fridge is. So my handy dandy husband decided to use this with the enclosure he built to go around it to keep our fridge from overheating and causing the fridge to continuously run and would freeze food in the fridge and our ice maker was not working right. With these 100° days we are already waiting till night to do laundry as it is...

Love it.

I had seen this used for years but never got the chance to use it myself. It works as advertised. It's a great protective barrier, super easy to install, and just works.

Deck joist butyl tape

Would Recommend

This joist tape is worth the money, self adhesive, super strong in my opinion, seals tops of deck joists so moisture doesn't impact wood, would highly recommend this product to anyone building a porch or deck,

Good stuff - wish the package was larger

Would Recommend

This is a nice product. It will definitely do the job. You really should protect the tops of your deck joists and this stuff is plenty sticky and should last. My only concern is the price and the size of the package. Seems like precious little product and at a faily high price.

Great waterproofing when building a deck

Would Recommend

This butyl rubber self-adhesive tape is the perfect dimension for the top of joists in a deck structure and it is intended for use during construction when one can access the top of the framing. See pictures. It goes on very easily after peeling the backing and cutting with a utility knife. See pictures. It can also be used for other waterproofing outside so a 50 foot roll like this has many great uses!
