Hi all, I am in the process of ripping apart my current darkroom and rebuilding it from scratch. It is located in the basement and the walls are crumbling cinderblock walls that tend to get damp...overall this provides a nice little dungeon effect. I would like to finish the darkroom w/ water+mold resistant drywall and was planning on using treated lumber for the furring strips that sit between the drywall and the basement wall. I want to avoid using regular untreated lumber because I am scared that it will provide a good base for a mold explosion. Does anybody know if the chemicals in treated lumber will have any negative effects on photographic paper that is stored in the darkroom? Thanks in advance.
