How to Prevent Mould and Mildew
Mould thrives in damp, dark places. It is often caused by condensation. In some cases, however, other damp problems can be the cause of mould growth on walls. Dampness in masonry can create a habitable environment for mould and result in a hidden mould infestation. Possible sources of dampness in masonry are rising damp, penetrating damp or even water leaks. To prevent mould growth due to damp inside masonry, all damp patches and signs of dampness should be fully investigated as soon as they appear. Such an investigation should ideally be carried out by a fully qualified damp surveyor in order to determine the correct source of dampness.
How to Prevent Mould and Mildew on Walls
Most commonly, mould appears on walls as a result of condensation. To prevent mould growth, a correct ventilation and heating regime should be adhered to. By exchanging damp air inside houses with fresh air from outside, moisture is less likely to condense on cold surfaces, such as walls. Additionally, not letting houses get too cold in winter ensures a less habitable environment for mould spores.
However, a correct ventilation and heating regime can not always fully prevent mould on walls. In some places, ventilating rooms can prove difficult, especially in bathrooms and kitchens. In these cases, it is recommended to use ventilators or extractor fans. To prevent further mould growth, walls and ceilings can be painted with a mould-resistant paint.
Dryzone Mould-resistant Emulsion Paint is a premium-quality coating designed to prevent mould growth on walls for at least 5 years. The paint is low in odour, quick-drying and compatible for overpainting on all known paint finishes. Once cured, the paint is fully washable, creating an easy to maintain environment.
Mould on walls can be caused by a variety of problems, mostly related to damp issues. When mould appears on walls and ceilings the cause of dampness should be found in order to stop mould spreading around the house.
