Installation
We’d like your mahogany deck installation to go as smoothly as possible, with the finished product’s appearance and performance maximized for your enjoyment. To this end, we recommend the following:
- Keep all your deck material clean and dry prior to treating and installation.
- D.J.’s Decking has an option for pre-staining with Sun Frog sealer to treat your deck materials with a penetrating sealer on all 6 sides prior to installation.
- Our decking is kiln dried; there is almost no shrinkage. Like all woods, though, it will absorb moisture.
- We recommend blind screw method with stainless steel trim head screws.
General Notes
- Mahogany is a kiln-dried hardwood.
- Kiln-dried deck boards will not shrink appreciably after installation. They will, however, expand during periods of high humidity or prolonged rainfall.
- Follow your local building codes.
Spacing Deck Joists
- Because of the strength of 5/4 mahogany decking, your deck can be framed 24” on center. 16” on center framing, while not necessary, will increase the strength and stability of your deck.
Spacing Deck Boards
- 4” deck boards should be spaced a minimum of 3/16” apart and 6” deck boards should be spaced a minimum of ¼” apart to allow for width expansion. This expansion does not affect the overall length of the board.
Fastening Deck Boards
- We recommend drilling pilot holes on the ends of each deck board to minimize splitting.
