Hi;
I am doing a tile project - installing ceramic tile over an area that was originally carpeted. It is in a bathroom, on a second floor.
Under the carpet there is the wood subfloor. I planned on just removing the carpet and pad, installing backer board, then tile.
When I pulled up the carpet right along the shower, there is black mold on the wood subfloor. I'm pretty sure it's not a leak, just the shower usage and dripping when the shower door opens. There is maybe a square foot area with this issue.
The wood seems OK structurally, it doesn't look rotted out at least and seems to just be mold on the surface.
Is there anything I can or should do to clean it up? Can I bleach it? Seems like putting any liquids or cleaners on wood is not a good idea. Maybe put a layer of the Killz primer on it?
Cutting out the section and replacing is probably not feasible, at least not for me to do, I'd have to go get a contractor for that I guess. The whole shower would have to be removed I think.
Thanks for any information.
