How to use it
- Type the deck
Its length along the boards and its width across them.
- Set the boards
Their width, the gap between them and the length they come in.
- Set the joists
How far apart the joists sit under the boards.
Tips
- Mind the gap
Leave the gap the board maker asks for, so water drains away and the boards have room to swell.
- Joins on joists
Where a row takes two boards, the join must sit on a joist. Stagger the joins from row to row.
- Two screws
Each board takes two screws at every joist it crosses.
