2025 Australian Decking Installation Guide

JOB SITE STORAGE MOISTURE PROTECTION

TEMPERATURES AT INSTALLATION If boards have been stored in a cold environment, or if installing in localities prone to large temperature shifts within a 24-hour period, its best to lay boards out on framing (DO NOT ATTACH OR CUT) to allow boards to acclimate to current temperatures BEFORE installation.

ALWAYS cover decking products, even on construction site, until ready to be installed to prevent moisture. Tannins (brown spotting) can be washed off boards if this occurs.

STORAGE REQUIREMENTS: Store decking on a flat level surface and ALWAYS use proper supports. DO NOT store directly on the ground. When stacking decking bundles, supports should start approximately 250 mm from each end and be spaced approximately 600 mm on center. In addition, supports should line up vertically/perpendicular to the decking product. Adjust supports accordingly if bundles are loose. (IMPORTANT TO NOTE THAT PROPER SUPPORT SPACING MUST BE IN PLACE FOR THESE HEIGHTS). When stacking multiple bundles, ensure that supports line up vertically down through each stack.

TOOLS NEEDED

Standard power drill

Mitre saw blade (254 mm—305 mm. 40 teeth or more)

Carbide-tipped blades

Trex groove router bit

Trex groove cutter

SAFETY

* Transcend decking: maximum stack height is 14 bundles. TREX AND STATIC ELECTRICITY

While this is not common, static electricity can occur on walking surfaces in dry climates or in areas where dry winds and dust-borne particles lay on the decking surfaces. Static electricity can build up on occupants walking across any composite decking surface, including Trex, then produce a small static shock if they touch a grounded metal surface such as a railing, door, etc.

Long sleeves

Safety glasses

Dust mask

Gloves
