2025 UK Decking Installation Guide

JOB SITE STORAGE

MOISTURE PROTECTION 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.

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. This condition can be decreased greatly with the use of a product call ACL Staticide ® . Two products tested were General Purpose Staticide ® and Heavy Duty Staticide ® . Both are effective at greatly reducing static electricity on Trex decking surfaces. Apply full strength, using a mop on a dry decking surface, and allow to dry. No rinsing, no diluting needed. Products are non-toxic, non-flammable, non-staining (will not change the color of decking surface), completely biodegradable and safe to use. Product is water based and may require a second application after rain or other weather conditions. Over a period of time, the effect of static will dissipate naturally on the decking surface. See link for more information on product: http:// www.aclstaticide.com/antistatic_coatings.html 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.

STORAGE REQUIREMENTS: Store decking on a flat level surface and ALWAYS use proper supports. DO NOT store directly on the ground. When stacking Transcend decking bundles, supports should start approximately 254 mm from each end (Enhance decking should start approximately 457 mm from each end) and be spaced approximately 0.61 m 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.

*Enhance decking, and 14 mm x 184 mm and 14 mm x 288 mm products: maximum stack height is 12 bundles. Transcend decking: maximum stack height is 14 bundles.
