Deck Board Spacing

notesAugust 22, 2011

Using composite. Temps are in the 80s - low 90s. What spacing should I use between boards, both side by side and at butt joints. Manufacturer says 1/4", but that sure seems big to me. Plus, I hate it when they shrink up and the gaps get even bigger. Thanks.

Composite doesn't shrink. It may grow in the heat. That is why the butt joint spacing is critical. Butt the ends tight and you'll end up with a wavy deck, if the sun shines directly on it.

Call the manufacturer and see if they'll warranty an install done with 3/16" gaps. I suspect they call for 1/4" to ensure maximum drainage and ventilation.
