I'm replacing a board on my deck and want to know how long do I need to wait before staining pressure treated wood?
I replaced several boards on my deck last spring. After installing them I immediately stained them to match the old. It is late September and I haven't had any problems with the staining of the PT'd boards.
The main concern with pressure treated wood is the moisture content. If the wood feels dry to the touch and water does not bead on the surface, you are probably OK to stain.
Can I install them on my deck now and then stain them in the spring when I plan to re-stain the entire deck?
Certainly. It is pressure treated and would last for years if you did absolutely nothing to it. Staining in this case is largely for appearances, although it will slow down the aging of the wood and cracking of the grain.
