Constantly improving on their innovative RainEscape drainage system, Trex has released Post Flashing for 4x4 wood posts to further prevent moisture penetration. The snug-fitting collar slides over a 4x4 post and is secured with a bead of RainEscape caulk as well as RainEscape butyl tape. A post sleeve can be used over the wood post and post flashing. If there isn't a post sleeve, the post flashing can be trimmed to the same height as the deck board so that the flashing will be concealed after the deck boards are installed. To estimate the materials you'll need we recommend using the Trex RainEscape materials estimator.
The Trex RainEscape deck drainage system can be installed using caulk, tape, and staples (sold separately). It is designed to be easily installed by any do-it-yourselfer to provide deck drainage while providing usable dry space underneath the deck.
The system protects against rot and can be adjusted to fit both standard and non-standard joist spacing.
Please note, this system can only be used for new projects; it cannot be installed on an existing deck.
