Fill a bucket with warm water and add a few drops of the soap, stirring gently to create a mild sudsy solution.

If the growth is particularly stubborn, you can add a cup of white vinegar to the water.

Moisture is the enemy of any painting or sealing process. Leave the bathroom door open and turn on the extractor fan, or set up a portable fan pointed toward the ceiling to speed up the drying process. Depending on the humidity in the room, this can take anywhere from a few hours to a whole day.

Resist the temptation to paint over a damp ceiling. If paint is applied over trapped moisture, it will fail to adhere properly, and the fungal problem will quickly return beneath the new layer, eating away at the paint from the inside out. Touch the ceiling gently with the back of your hand; if it feels cool or damp, wait longer before proceeding to the final stage.

Seal and Paint the Ceiling

Once the surface is completely dry, you may notice that the paint has faded or that permanent stains remain visible. To prevent the problem from recurring, apply a specialized anti-mould primer to the affected area using a standard paintbrush or small roller. This primer creates a barrier that stops moisture from feeding any remaining microscopic spores.

After the primer has cured according to the manufacturer instructions, apply a coat of moisture-resistant bathroom paint. Bathroom paints are formulated with additives that discourage fungal growth in high-humidity environments. Feather the edges of the new paint into the surrounding old paint so the repair blends seamlessly. By taking the time to clean with a soft brush, dry thoroughly, and seal properly, you ensure a lasting, clean finish overhead.
