Dealing with mould and mildew can be a common issue in damp areas like bathrooms and kitchens. Not only are they unsightly, but they can also pose health risks if left untreated. One effective way to address this problem is by painting over the affected surfaces. In this article, we will discuss the possible causes of mould and mildew growth and provide a step-by-step solution for painting over them, ensuring a fresh and clean appearance in your bathroom or kitchen.
Possible Causes of Mould and Mildew
Mould and mildew tend to thrive in environments that are damp or lack direct sunlight. Bathrooms, kitchens, and laundries are particularly susceptible to their growth. Apart from the environmental factors, the following can also contribute to the development of mould and mildew:
- Use of Alkyd or Oil-Based Paint: Using these types of paints, especially in areas prone to moisture, can create an ideal breeding ground for mould and mildew. The high moisture content in these areas can cause the paint to trap moisture, leading to mould growth.
- Lower Quality water-based Paint: Choosing a lower quality water-based paint that does not have adequate moisture resistance can promote mould and mildew growth. Inferior paints may not have the necessary protective properties to prevent moisture penetration.
- Failure to Prime Bare Wood Surfaces: If bare wood surfaces are not properly primed before applying paint, moisture can seep into the wood, leading to mould and mildew growth. Priming helps create a barrier that protects the wood from moisture intrusion.
- Painting Over Pre-existing Mildew: Ignoring existing mildew and directly applying paint over it will not solve the problem. The mildew will continue to grow beneath the paint layer, eventually reappearing on the surface.
Solution: Painting Over Mould and Mildew
Step 1: Test for Mildew
Before proceeding with painting, it is essential to confirm the presence of mildew. To test for mildew, apply a few drops of household bleach to the affected area. If the discolouration is bleached away, it is likely mildew.
Step 2: Remove Mildew
To remove mildew, scrub the affected surface with a diluted household bleach solution. Mix one part bleach with three parts water and use a brush or sponge to scrub the area thoroughly. Be sure to wear protective gloves and ensure proper ventilation during this process.
Step 3: Rinse Thoroughly
After scrubbing, rinse the surface with clean water to remove any residue from the bleach solution. This step is crucial to ensure that the surface is clean and ready for painting.
Step 4: Choose a Top-Quality Water-based Paint
To prevent future mould and mildew growth, select a top-quality water-based paint with excellent moisture resistance properties such as Plascon Kitchens & Bathrooms or Plascon Velvaglo Water-based Enamel. Look for paints specifically designed for high-moisture areas like bathrooms and kitchens. These paints are formulated to resist moisture and inhibit mould and mildew growth.
