Abstract
This 8-month comparative study evaluates antimicrobial coating effectiveness for mould prevention in 45 high-rise condominium units across 3 premium residential districts in Singapore. Results demonstrate 94% reduction in mould recurrence on treated surfaces compared to untreated control units, with particular effectiveness in bathroom ceilings, bedroom corners near air conditioning units, and wardrobe interiors.
Introduction
Mould growth in Singapore condominiums represents a significant quality-of-life issue affecting thousands of residents annually. Despite regular cleaning and air conditioning, many units experience recurring mould problems, particularly in premium high-rise developments where sealed building envelopes and powerful air conditioning create significant temperature differentials.
