What is the difference between standard and premium pressure treated wood?
Premium grades of pressure-treated wood are usually easier to find at lumber yards than at home centers. In addition to being drier, premium wood generally has fewer knots, resulting in a better looking deck. … Some deck builders leave a small space of about 1/16-inch between deck boards, using a nail as a spacer.

Can pressure treated lumber touch the ground?
Pressure-treated wood is softwood lumber, typically southern yellow pine, that’s been chemically treated to resist rot, decay and termites.
