Review: A Reliable Waterproofing Solution for Deck Construction - 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.
Review: Good product to use - We are at the prep stage of putting in 20 joists for our decking. The tape is easy to use, seems to be good value and easy to apply. I think it looks very professional once on and we have high hopes of it helping to slow down the rot on the joists.

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.
