Can I use 1×6 for deck floor?

Width of material: We recommend only 1×4, 5/4×4 or narrower boards. Never use 1×6 or 5/4×6 material in close to ground applications.

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 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.
