If mould keeps coming back in a bathroom, kitchen or on a cold external wall, the right anti mould paint can keep it at bay for years. But not all mould-resistant paints are the same, and none of them work if the wall underneath is not prepared properly. Here is what anti mould paint does, which products we rate, and how to get the best from them.
An anti mould paint (sometimes called mould resistant paint) carries a fungicide within the dried film. That biocide keeps working long after the paint has cured, stopping spores from establishing on the surface. Ordinary emulsion has no such protection, which is why mould returns so quickly on untreated walls in damp rooms.
This is the honest bit: anti mould paint manages the symptom, it does not fix the cause. If a wall is wet from condensation, penetrating damp or poor ventilation, even the best coating will eventually be overwhelmed. Always clean, kill and dry the surface first, and deal with the source of moisture. Our guide on how to remove mould before painting walks through that prep step by step.
For cold walls and ceilings where condensation forms, an anti condensation paint adds an insulating, moisture-tolerant layer that helps stop the surface reaching the temperature at which damp settles. Ask us in store if that sounds like your problem.
Prepare as above: kill any existing mould, let the wall dry fully, and spot-prime stains. Then apply the anti mould paint in two full coats, respecting the recoat time on the tin so the fungicide cures properly. Keep the room ventilated while it dries. Done right, you should get years of clean walls rather than months.
Tell us the room, the problem and the finish you are after and we will point you to the right tin and mix the colour in store. Browse the full anti-mould paint range online, with free UK delivery over £100 or collect from our Bucksburn shop in Aberdeen.
