Pressure-treated wood makes a very affordable deck that can be extremely sturdy and quite attractive when designed with the lumber’s attributes in mind. (For example, interesting angles and bold shapes keep the focus on form rather than the details of the wood itself.)
There are regional variations in the wood species used for pressure-treated lumber. East of the Mississippi, southern yellow pine is most commonly used. Southern yellow pine can be treated throughout its sapwood. Its heartwood is not treatable but is naturally resistant to termites and decay. West of the Mississippi, it’s usually Douglas-fir or spruce/pine/fir. These require incision to provide sufficient penetration of treatment chemicals.
All wood exposed to the elements will swell and shrink as it undergoes wet and dry conditions. As the wood dries, or "seasons," it develops "checks." Checks are thin cracks that usually run parallel to the grain. This occurs most dramatically with pressure-treated wood, especially southern yellow pine. It won’t harm the structural integrity, but it will cause changes in the wood, particularly in decking, rail posts, rail caps and columns.
Decking is exposed to the weather on top yet is more protected underneath. The different levels of swelling and shrinking from top to bottom cause cupping. The lumber used for posts and columns is typically cut from near the center of the tree, which has both heartwood and sapwood. Heartwood contains a higher level of resin, which causes it to shrink at a different rate than sapwood, producing checking. But, again, minimal checking does not harm structural integrity.
However, repeated swelling and shrinking can cause excessive checking, splits, cupping, warping and raised grain. That’s why pressure-treated wood needs to be protected by an application of penetrating sealer. This slows down the rate of shrinking and swelling, stabilizing the wood and minimizing the damage of that cycle. Sealer should be reapplied, usually every one to two years per manufacturer’s recommendations, to keep your deck protected.
If you have chosen paraffin-enhanced pressure-treated wood, your deck surface is already stabilized. Cupping may still occur but should me more minimal. However, periodic application of a deck sealer is still needed.
Depending on your project, Archadeck may pre-treat or pre-stain certain (namely, soon-to-be-difficult-to-access) sections prior to construction. Post-construction, you may have Archadeck treat your deck or arrange for such treatment for you. Kiln-dried wood can be treated immediately, but other wood will usually need to dry before any sealant or paint can be applied.
