Get to understand the basics of deck building.
Butt joints should be between 8mm - 12mm to allow the boards to expand and contract.
Butt joints should be supported by two lengths of joist, one for each decking board.
A fastener should be used at the end of each decking board, at a butt joint and not shared across two decking boards.
20mm should be left around the deck, next to solid structures.
Joist centres should be no more than 300mm.
The base should be solid such as concrete or hardcore.
The decking should slope at around 5mm per meter towards a drainage area to allow water to drain easily
Any composite product should not be directly screwed through, excluding joists.
Composite joists should be predrilled.
Only Trade Decking Supplies fasteners are compatible to be used with Trade Decking Supplies composite decking products.
Lay joists 30cm apart to create a substructure for the composite decking.
Screw the starter fasteners into each joist. We recommend pre-drilling holes to prevent the joists from cracking.
Slide the first decking board up to the starter fasteners and secure with hidden fasteners on the opposite side. Apply a fastener to each supporting joist. We recommend pre-drilling holes to prevent the joists from cracking.
Fit the next board by sliding it onto the hidden fasteners used to secure the previous joist and fit another set of hidden fasteners to secure the opposite side of the board, again use one fastener for each supporting joist. Repeat until second to last board.
Add starter fasteners to the end of the joists where the last board will comfortably fit. Leave space for the second to last board and add the end board.
Add the final (second to end) board
Slide hiden fasteners between the decking gap and align with each joist.
screw the fasteners between the joists to secure the last two decking boards in place. The decking should now be finished. Add fascia boards or corner trims as required.
