Frequently Asked Questions
How long does anti-mould paint protection last?
Quality anti-mould paints provide protection for 3-5 years in normal conditions. In high-moisture bathrooms, expect 2-3 years. Effectiveness depends on humidity levels, ventilation, and surface preparation. Signs protection is fading include visible mould spots or musty odours.
Can I apply anti-mould paint over existing mould?
No. Mould must be completely removed and treated before painting. Paint applied over mould will eventually fail as the mould continues growing beneath. Proper preparation includes removing all visible mould, treating with antimicrobial solution, and allowing complete drying before painting.
Is anti-mould paint worth the extra cost?
Yes, especially for bathrooms and kitchens. Anti-mould paint costs 20-40% more than regular paint but prevents costly mould remediation and repainting. For a typical bathroom, the extra cost is $50-100 - much less than professional mould removal.
What colour options are available for anti-mould paint?
Most anti-mould paints come in white and can be tinted to various colours. However, very dark colours may reduce effectiveness. Pastel and light colours are recommended. Check with paint suppliers about tinting limitations for specific anti-mould products.
