Mould-Resistant Paint: How It Works & Top Recommended Products

1. Understanding the Science Behind Mould-Resistant Paint

Mould-resistant paints are formulated with anti-fungal and anti-bacterial additives that prevent the growth of mould and mildew on painted surfaces. These additives, often based on zinc pyrithione or silver ions, create a hostile environment for mould spores by disrupting their cell walls and inhibiting reproduction.In humid or poorly ventilated areas (like bathrooms, kitchens, and basements), this protection is especially crucial, as high moisture accelerates fungal growth.

2. Key Benefits of Using Mould-Resistant Paint

• Long-lasting protection: Extends the repainting cycle.

• Improved hygiene: Reduces allergens and musty odours.

• Better appearance: Prevents dark spots, discolouration, and peeling.

• Easy maintenance: Can be cleaned without damaging the coating.

3. Where to Use It

• Bathrooms and laundries: High humidity areas prone to condensation.

• Kitchens: Behind stoves, sinks, and splash zones.

• Bedrooms & living rooms: Especially in coastal or humid regions.

• Ceilings & window frames: Areas with poor airflow or condensation.
