Can you use 2×6 for deck flooring?

Should I use 2×6 or 5 4 decking?

Should I leave a gap between decking boards?



Determining Deck Board Spacing
When using wood decking, you want a gap of at least 1/8 of an inch after your decking has dried out. If you’re using decking that’s already been dried out, you can leave a 1/8-inch gap when you install. Many decks will use “green” wood, or wood that hasn’t been dried down or kiln dried.

Should deck boards have a gap?

Proper deck board spacing should have a 1/8-inch gap after the decking has dried out. If you install your decking using wet boards, pressure-treated decking that has not yet dried out, then you should install them with no gap as a gap will be created as they dry and shrink.

Should you nail or screw deck boards?



Decking screws are better than nails when building a deck. Decking screws hold down your decking more securely than nails and will stop your decking from warping. Also, you can easily remove screws for deck maintenance without causing damage.
