Conventional emulsion paints consist for the most part of polymers. They often contain solvents, plasticisers or preservation agents. These substances in paints continue to pollute room air even months after paint has been applied. At the same time, conventional paints form a dense film on the surface of walls that impairs the vapour permeability of the walls . Conventional paints cause deterioration in air quality, whilst the risk of mould increases due to moisture condensing on the walls.
By contrast, anti-mould paint by KEIMFARBEN enables an outstanding exchange of moisture between the surface of walls and the air in the room. Our paints are open-pored and completely vapour permeable. They are the ideal mould-preventing wall paints. Keim paints prevent humidity present in rooms from condensing on walls or coatings. Mould formation, for example behind cupboards, at window soffits or in bathrooms is thus by and large ruled out with our paints. This makes Keim paints automatically and naturally "anti-mould”: their vapour permeability and mineral raw material base makes them ideal for avoiding mould within your house.
KEIM paints are alkaline. The high pH value that is typical of silicates is also especially mould-inhibiting. In contrast to anti-mould paints and other paints available in DIY stores, Keim paints have a natural, long-term mould-preventing effect. These are healthy paints. Above all, they contain no biocides and therefore offer optimum protection when applied to your walls.
If mould infestation has already occurred, we recommend using our mould-preventing products and paints for the remediation process.
Mould and fungi can be found everywhere. They form an important ecological component in our natural environment: mould and fungi break down organic substances into a source of nutrients for plants. Moisture is a key factor in mould formation. Homes and interior rooms have many sources of moisture.
The growth of mould and fungi is determined by four factors: moisture, nutrient supply, temperature and the pH value of the substrate.
Protection from mould generally entails:
Avoiding moisture and damp building components
Repairing building defects and damage caused by moisture
Using vapour permeable silicate paints
How to ventilate correctly:
- Regular ventilation of the rooms with wide open windows for about five to ten minutes often prevents mould formation.
- Ventilate immediately after cooking or taking a shower to prevent higher humidity levels in the house. This can result in lots of moisture on the various substrates and paints. An air dehumidifier can help to remedy the situation in bathrooms without windows
- Do not put furniture or hang curtains in front of the radiators: this not only increases your energy consumption but also means that the air is not heated up adequately. As a result, damp air condenses more quickly on the walls.
- Do not put cupboards too close to the walls. This prevents adequate air circulation so that the moisture contained in the air condenses on the walls and wall paints, particularly in the case of poorly insulated, cold outer walls.
If you detect mould in your home, e.g. as mould stains, you should act as soon as possible and remove the stains. Mould and fungi distribute their spores in the air, where they multiply explosively under the right conditions. Microorganisms such as fungi and bacteria are a natural part of our environment and people can normally tolerate them without a noticeable reaction. But if the mould concentration exceeds a certain level, this can cause a number of serious illnesses, such as respiratory diseases, asthma, allergies and susceptibility to infections, as well as fatigue and headaches.
Successful, sustainable mould remediation depends not only on correct and professional treatment of surfaces infested by mould, such as coats of paint, but always includes fighting the causes and eliminating the damage.
