We recently tore down our 30 year old redwood deck, and rebuilt using pressure treated lumber. Now my father in law tells us not to stain the wood for at least 1 year. We thought it should be stained and protected for the coming winter. Is he right, or can we go ahead and stain?
Answer:
There is nothing you're going to do to PT wood to extend its life so why create yourself an annual painting project? I'd leave it alone.
