I'll be doing a small bathroom remodel on a VERY old house which mainly includes installing bathroom fan and a full paint job as the main tasks. On first walk through, I noticed that the house has visible black mold on the plaster walls and ceiling (I'm assuming this is plaster too...) inside of the combination bath/shower.
Along with the visible mold, the paint on those surfaces is deteriorating and badly peeling (which is the original reason I was called for painting).
I explained to the homeowner that since the original bathroom had no exhaust fan or proper venting, this was the perfect condition for moisture to build and mold to grow, so we added bathroom fan as a requirement. I said I would research ways to remove the mold and properly prepare the surfaces before painting.
I am thinking:
- Physically scrape away all peeling paint, and dispose.
- Pre-spray all areas with vinager, and let set for 1 hour.
- Deep scrub all areas w/ Borax or TPS.
- Fully DRY for 24 hours.
- Prime with KILZ.
Any feedback on this plan? Also -- anything special I need to do since the walls are PLASTER and not regular drywall?
