Mould is a major headache for many households throughout the country which if left unchecked may cause an unsightly, unpleasant and unhealthy living environment. From the 27th October 2025, Awaab's Law makes it mandatory for social landlords to fix serious mould and damp problems quickly. To support healthier homes and workplaces, Brewers stock a wide range of products to prevent mould and keep places clean.
Wherever there is little ventilation and a recurring source of moisture, mould and mildew will be a problem, so it's important to make sure you're using the right products and doing what is needed to increase ventilation.
Once the root of the mould problem has been found and fixed, applying the right paint finish afterwards will help withstand moisture and prevent mould growing.
These finishes can also be used in rooms with higher amounts of moisture such as kitchens and bathrooms.
Where Does Mould Come From?
Mould mildew is a form of fungus propagated from spores present in most atmospheres when in damp conditions.
Any environment in which the relative humidity exceeds 70 per cent for lengthy periods provides sufficient moisture.
Mould growths are not usually particularly destructive to paint films unless the infection is deep seated or well established but they are unsightly and often difficult to eradicate.
They usually have a greyish or sooty appearance although some forms are coloured or produce stains which discolour the surface.
What About Algae?
Like mould, algae on exterior surfaces only thrives in the right conditions; plenty of moisture and nutrient on the surface, often from nearby vegetation.
It is not possible to change the environment other than by removing adjacent shrubs and trees, but the remedial treatment is similar to that for mould growth.
It is best practice to always use fungicidal wash before painting an exterior surface to prevent algae build up.
