I recently used Dongxw Butyl Joist Tape to protect the joists and beams of my new deck from water damage. I was impressed with the quality of the tape and how easy it was to apply.The tape is made of a thick, durable butyl rubber that is waterproof and resistant to UV rays. It's also self-adhesive, so it was easy to apply to the joists and beams. I simply cut the tape to the desired length and pressed it onto the wood. The tape adhered well and created a tight seal that will prevent water from seeping into the wood and causing rot.I'm confident that the Dongxw Butyl Joist Tape will help extend the life of my deck by protecting the structural members from water damage. I would definitely recommend it to anyone looking for a reliable waterproofing solution for their deck construction project.

Was installing some decking and only needed a small amount to make the top of the beams waterproof.Was easy to install, good value for money for what I needed it for in my project and went onto the beams really well.

very professional tape very strong adhesive, stays in place. very good product

fast delivery, sticks well once applied but applying it is hard work as the backing tape keeps splitting, trying to level up the the split in the backing tape again makes for a sticky mess.

Very strong tape, does the job, thanks

Just the job for weather-proofing exposed wooden joists. Used on replacement beams for a garden loggia. Originals, although pressure-treated, had rotted after 10years with water pooling on flat top surfaces.

Bought two lots of this tape for a Decking project.First lot fine, does what it should. Had to buy some more.First lot has a clear fairly thick backing which has to be removed.Second lot different labelling but same stuff from same manufacturer BUT with a different backing.The second lot has a blue backing tape which rips at edges every time you remove it, leaving you try and pull off “threads” of the ripped backing.Unless you remove it it won’t adhere properly.Due to the nature of the tape it is incredibly sticky and it’s as frustrating as hell trying to remove ripped traces of this blue backing.I should have returned it as not being usable but stuck as needed to finish the decking.So I likely wasted an extra hour removing endless bits of this blue backing to use the actual tape.Clearly manufacturer has cheapened the manufacturing costs with this fragile backing which will cost you hours !!!If you get the stuff with blue backing, send it back, you’ll thank me !!!
