Frequently Asked Questions
What is the actual size of a 5/4 x 6 deck board?
1 in. thick by 5.5 in. wide at time of manufacture, with radius edges. Treated boards can vary slightly with moisture as they season.
Why ground contact for a deck surface?
Deck boards collect debris and stay wet at fastener lines and board gaps. Ground contact retention covers that service plus stairs and framing near grade, so one class serves the whole deck.
When can I stain it?
After the board seasons, when water no longer beads on the surface, typically several weeks exposed. Follow the finish maker's instructions for treated lumber.
How is it sold?
By the board in the length you select, quoted by count against the deck take-off.
