If you need to paint over bathroom mould, you should first ensure that an expert has concluded that the mould is nontoxic and that the problems that led to the mould outbreak have been rectified. In addition, you will need to kill the mould and apply a special kind of sealer or you will eventually see a reappearance at some point in the future.

Consult an expert to determine whether or not the mould is toxic and ensure that the source of the mould has been eradicated.
Cover the bathroom flooring with heavy-duty fabric dust sheets.
Don rubber gloves.
Add one teaspoon of bleach to a spray bottle filled with water. Spray the mould with the bleach solution. Allow the solution to sit for two minutes, then rinse the surface thoroughly with wet rags. Dry the wall with towels.
Cover areas you do not want painted with blue painter's tape.
Coat the mould with Kilz stain-blocking spray primer. Allow the stain blocker to dry for two full hours.
Apply a coat of acrylic latex paint to the wall using a roller. Paint areas inaccessible to the roller using a latex paintbrush.
