How to Clean Mould Off Bathroom Walls Before Painting

Mould growth in bathrooms is a common problem that can be unsightly and unhealthy. If you're planning to paint your bathroom, it's important to clean the walls thoroughly to remove any mould spores that could cause future outbreaks. Here's a step-by-step guide on how to clean mould off bathroom walls before painting:

1. Identify the Type of Mould

There are many different types of mould, and some are more harmful than others. If you're not sure what type of mould you have, it's best to consult with a professional. However, most bathroom mould is caused by Aspergillus or Penicillium, which are relatively common and can be treated with household cleaning products.

2. Safety Precautions

Before you start cleaning, it's important to take some safety precautions. Wear gloves and a mask to protect yourself from mould spores. Open a window to ventilate the room and keep the area well-lit.

3. Remove Loose Mould

Use a soft brush or cloth to gently remove any loose mould from the surface of the walls. Avoid scrubbing too hard, as this can spread the mould spores.

4. Apply a Mould-Killing Solution

Mix a solution of one part bleach to three parts water. Apply the solution to the affected areas using a spray bottle or sponge. Allow the solution to sit for 15-20 minutes, then rinse thoroughly with clean water.

5. Dry the Walls

After rinsing the walls, use a clean towel or cloth to dry them thoroughly. It's important to make sure the walls are completely dry before you start painting, as moisture can encourage mould growth.

6. Paint the Walls

Finally, you can paint the walls. Use a mould-resistant paint specifically designed for bathrooms. Apply two coats of paint, allowing each coat to dry completely before applying the next.
