Just finished new deck using CCA wood. Was ready to use a watersealent when friend told me that I should not seal cca wood for at least a year, so wood could breath. I thought I should seal it asap. Please advise. Dan

Contrary to popular belief, waiting 6 - 12 months is not necessary and can actually damage the wood.

UV Rays begin working on a deck immediately breaking down the wood fibers. We recommend to give your deck a good quality sealer as soon your deck is build. If you prefer a semi-transparent stain, wait 3 to 6 weeks (depending on season).

During the Spring and early Summer most P.T. woods tend to be very green because of demand, give the wood a extra 2 weeks before applying any sealer or stain.

I would recommend sealing this within 2 - 3 weeks, despite what your sealer manufacturer says.

Hope this helps!
