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.

Well.....water isn't good for wood, but that is why there is mildew on
the wood. *I would
brush on a mix of water/bleach, not too strong, wipe, rinse quickly,
wipe, let dry, and
proceed. *I would not let the bleach stand for long or soak into the
wood, as it probably,
over time,would cause some deterioration. *Since the wood is sound, the
amount of
leakage has probably been minimal.- Hide quoted text -

Bleach wont hurt sound wood, it evaporates to salt, I would pour it on
and let it soak and dry by itself, it will just kill anything in the
wood.
