How to Remove Mold on a Bathroom Ceiling


It is not uncommon to find mold growing in various areas of your bathroom. Mold requires a damp, dark and humid location to grow and thrive, which makes bathrooms the perfect breeding ground for mold and its spores. If mold is not dealt with in a timely manner, it can eat away at the item and deteriorate it beyond repair. Mold growing on your ceiling could be a sign of a ventilation problem which you should look into after the mold has been removed.

Things You'll Need

  • Water
  • TSP
  • 2 Buckets or containers
  • 3 Sponges or cloths
  • Bleach
  • Stain killing primer
  • Mildew resistant top coat
  • Combine 2 cups of warm water with ¼ cup of TSP---trisodium phosphate---in a bucket or container.

  • Saturate a sponge in the solution and wring out the excess mixture.

  • Scrub the bathroom ceiling with the sponge. When the sponge becomes dirty, resaturate it in the solution. Continue scrubbing until all mold is gone.

  • Pour undiluted bleach in a small container. Submerge a sponge or white cloth in the bleach and wring out the excess liquid.

  • Wipe the bathroom ceiling with the sponge. Allow to sit for a few hours.

  • Dampen a clean cloth with cool water. Rinse the bathroom ceiling with the cloth.

Tips & Warnings

  • After the ceiling has dried, prime the bathroom ceiling with a stain killing primer and apply a mildew resistant top coat to prevent mold growth.
  • Wear rubber gloves when working with chemicals to prevent skin irritation.
