How much gap should I leave for expansion or contraction ...

For areas that are subject to significant temperature swings, we recommend installing your deck boards using surface fasteners. First, ensure that the deck boards are aligned properly. Then, install a fastener in the middle of each board length to prevent shifting during thermal expansion and contraction.

The Deck Handbook, Part 5: Problems With Composite Decking

Mildew build-up on a Composite Deck. N ormal use of the deck wears off the protective plastic coating that surrounds the wood particles in the composite, leaving them exposed to mold and mildew.. Wood in its natural state contains chemicals that fight off fungus. But, the wood flour used in composites has had most or all of these protective chemicals removed, so it is very vulnerable to mold ...
