Anti-mould (fungicidal) paints contain additives designed to inhibit mould growth on the painted surface. They’re widely available, cheap relative to other treatments, and genuinely have a role — but it’s a narrower role than the packaging sometimes suggests.<\/p>\n
A fungicidal paint slows or prevents mould re-establishing on the painted surface itself, for a limited period (the fungicidal additive depletes over time, typically needing repainting every couple of years in a persistently damp area). It doesn’t address why the surface is damp in the first place.<\/p>\n
Anti-mould paint works best as a supplementary measure in a room where you’ve already fixed the ventilation problem (or are actively managing it) but want extra protection against recurrence — for example, a bathroom ceiling that’s prone to condensation despite a working extractor fan. Used as the only<\/em> response to a persistent mould problem, without addressing ventilation or an underlying leak, it usually just delays the mould’s return rather than preventing it.<\/p>\nBefore applying it<\/h2>\n
