Mold Knowledge Base

Can you provide any insight into how green-treated (aka pressure treated) wood deals with mold?

It essentially makes it more resistant to water damage and mold growth. Mold can still grow on it, but the wood is more resistant to the fungi. This process isn’t a silver bullet though. You still want to practice common sense and make sure the products dry out properly when wet. While pressure-treated wood helps resist mold growth, it can’t function properly on wet or damp lumber.
