In this article, we feature a deck built by Maine Deck Company to demonstrate how they used Imus Seal joist flashing tape and Imus Cap joist caps to flash the deck substructure. This 10’ x 12’ deck required 20 pieces of Imus Cap (1-5/8" x 95") and a roll of Imus Seal (4" x 50').
Deck-to-house attachment areas are a common place for water damage. To prevent problems caused by moisture, spacers flashed with Imus Seal were used between the house and ledger.
After the deck framing was complete, Imus Seal was applied on top of the double 2" x 8" ledger and wrapped around the joist ends to prevent corrosion of the galvanized joist hangers by creating a barrier between them and the pressure-treated wood. Imus Cap was then installed on the joists.
Garapa Gray DuraLife Decking was installed with Fastenator fasteners. The Fastenator system worked well with Imus Cap and the screws easily penetrated the 26 gauge bonderized metal without the need to pre-drill or use self-tapping decking screws as demonstrated in the video.
