Decking Tips & Advice

• Use the CONCEALoc^® bracket to fix the first and last board.
• For the neatest possible finish, pre-drill 4mm pilot holes (do not countersink).
• When face-fixing boards, drive each screw until the screw’s head is flush with the surface of the board. Do not over-drive.
• TimberTech decking is easy to install with no special requirements. We recommend standard woodworking tools and standard pressure-treated softwood timbers for the sub frame. TimberTech deck boards can be drilled, nailed, sawn or routed, with no danger of rot.
• Maximum span between joists is 400mm for residential decks.
• We recommend a 3-4mm gap between boards (CONCEALoc® is designed to automatically create a 4mm gap between the boards).
• To aid water run-off, the deck should slope 13mm for every 2.44m away from the house.

EasyFix

• Available in 2 heights: 10mm or 38mm
• Decide what height timber joists to use, paying attention to the height of any existing door thresholds. Pressure-treated 50mm wide softwood timber joists should be used. You can select the height of timber joists to suit your installation (generally between 50-100mm high).
• Fit EasyFix shoes at gaps of 400mm down the length of the timber joists. We recommend 8 per m² for joists at 400mm centres on residential decks.
• Lay out the timber joists. When making a butt joint in joists, always leave a 15mm expansion gap and ensure that the joint is supported by a vertical post.
• Fix a timber joist noggin at intervals of 1.2m.
• Use EasyFix packers to assist with levelling the deck.
