My husband is installing a new deck with pressure-treated lumber at our home in Tennessee. How long does he need to wait to paint, or should he stain the deck now?. Older wood is drier and very porous. It will absorb most any type of wood stain and be adequately protected. New pressure treated pine on the other hand has higher moisture content and therefore is much denser making deck stain penetration more difficult. Pressure treated wood is a must for many outdoor projects, but it requires different handling than untreated woods.
How long should I wait to stain pressure-treated lumber and why do I have to wait? What if I decide to stain the pressure-treated decking or wood before it’s dry – are there any consequences?. Lastly – how often should I plan on re-staining the wood? Thanks in advance for any advice/ideas. PT warps because it is still wet from the pressure treating. I agree using dried PT is better. Solid Color Decking Stains are ideal for use on most types of lumber including redwood, cypress, pine and fir, as well as pressure-treated wood. Oil decking stains 1600 and 7600 are also excellent for mahogany, cambara, meranti, and other exotic wood species.
The Role of Stain in the Manufacture of Pressure Treated Wood Products. About twenty years ago, manufacturers began experimenting with wood stains because they were having trouble marketing their pressure treated lumber.
