Butyl Tape for Waterproofing Decking

Wood framing, posts, and joists will begin to rot and break down in approximately 8-10 years. Protect the wood with butyl to create a moisture-free barrier that will extend the life of your deck.
Butyl is also very easy to work with. It can be applied in cooler temperatures and can adhere to wood even in a damp environment
It is flexible and resilient. Perfect for long-term use and easy to use for repairs.
