Default Bathroom mould

I was pulling out the cracked silicone around my bathtub liner to redo it and the bottom 6-8 inches all around is black with mould.

now… if I was working and had more money right now i would just redo the whole thing, but I am un-employed and near broke.

I was thinking of just re-caulking the whole thing to prevent more moisture from getting in there and then redoing the bathroom when I have more $$ anyone have any thoughts on this?

If you're short on cash then caulking to prevent more moisture is the best bet.

Unfortunately black mould isn't very good.. hopefully it will dry out but it likely won't in a bathroom.

Last time we had black mould in a bathroom the shower stall caved in.. then we had to replace all of the drywall (30 year old house.. no green board or concrete backer board) and some of the studs.

The other thing that happens sometimes is that the black mould could be feeding from a leak that is somewhere else.

Keep the room as dry as possible. Run the fan (if you have one) most of the time to keep it dry. Open a window whenever you take a bath or a shower to help get the moisture out of there.

Good luck!

The bathroom is beside the stairway to the bathroom and the stairway has a big patch where the drywall has been replaced behind the shower, unfortunately the drywall behind the surround is not green board or anything like that. It sucks. I am laid of and on ei and have the time to fix-up the house but not the $$.. Oh well.. Caulk it up and when I get saved up ill do it proper.

Go to home depot... Get yerself lots of bleach, and I think they had some injectable anti-mold sprays (ie spray it into a cavity) - kill what you can; then cover it up good until you have time/money again. Sharpy note saying "fix mold" on the tile would be smart so you have a reminder

I had some mold on the rim joist of the new house (big saga with the builder and City re: vapour liner) and what I ended up doing was got a spray bottle with bleach (can also try Pinesol) and wet everything down.

Let dry before covering.

As a professional painter, we often run into mold. If its just surface mold, bleach will do the trick to kill it(there are also products out there specificaly designed kill and prevent mold), but if the mold has gotten deep into the drywall, the drywall will need to be replaced at some point. Sealing it up for the time being should prevent excess moisture and slow down the growth as well as prevent the mold spores from getting airborn but it will most likely continue to grow and spread behind the tub liner.
