Deck Joist waterproofing

There are a number of shield barrier products available to wrap your pressure treated deck framing materials with to prevent water damage and hardware corrosion. Most of these products are sold as rolls of self adhesive peel and stick flashing tape. Some builders install this material over the tops of joists for extra insurance against rot caused by water. Other builders use this material as a barrier between ACQ pressure treated wood and hardware to prevent corrosion.
