Do deck boards need to be pressure treated?
Similarly, should deck boards be pressure treated?
Pressure-treated lumber is the logical choice for the structural part of your deck—the posts, joists, beams and other members you normally don't see. Pressure-treated lumber can support more weight and span longer distances than cedar, redwood or other woods commonly used for building decks.
Beside above, do you need to seal cut pressure treated wood?
Use Cut-N-Seal® on areas that have been drilled or saw cut in treated wood deck boards, railing, post tops, fence boards, etc. Cut-N-Seal is not recommended to replace pressure treatment. Do not use to recoat pressure treated wood surfaces.
