What anti mould paint does
Anti mould paints contain fungicides that stop mould growing on the paint film for a period of time, often a few years. In bathrooms and kitchens they also resist moisture better than standard emulsion.
What it cannot do
- It will not kill mould already in the plaster underneath
- It will not stop condensation, leaks or penetrating damp
- It will not last if the wall stays wet
How to use it properly
- Find and fix the moisture cause
- Remove the mould with a fungicidal wash and let the surface dry
- Apply a stain block primer so marks do not bleed through
- Apply two coats of anti mould paint
Our view
Anti mould paint is a good finishing coat and we use it on most bathroom and bedroom jobs. It works best as part of a full mould treatment with better ventilation.
