Mould-free living with KEIM paints

Paints by KEIM - The optimum mould-preventing wall paints

Conventional emulsion paints consist for the most part of polymers. They often contain solvents, plasticisers or preservation agents. But these substances in the paints continue to pollute the room air even months after the coating has been applied. At the same time, the paints form a dense film on the surface of the wall or ceiling that sustainably impairs the vapour permeability of the walls or ceilings in the indoor setting. The paints cause a deterioration in the air quality, while the mould risk increases due to moisture condensing on the walls and ceilings. By contrast, the anti-mould paint by KEIMFARBEN permits an outstanding exchange of moisture between the surface of walls and ceilings and the air in the room. Our paints are open-pored and absolutely vapour permeable. They are the ideal mould-preventing wall paints. They prevent the humidity present in the rooms from condensing on the walls or coatings. Mould formation, for example behind cupboards, at window soffits or in bathrooms is thus ruled out by and large with our paints. This makes them quite automatically and naturally "anti-mould wall paints": their vapour permeability and mineral raw material basis makes them particularly ideal for avoiding mould within your four walls. 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, our wall 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 being applied to your walls and ceilings.

If mould infestation has already occurred, we recommend using our mould-preventing products and paints for the remediation process.

Causes and emergence of mould

Mould fungi can be found everywhere. They form an important ecological component in our natural environment: mould fungi break down organic substances and make them accessible to plants as a source of nutrients. Moisture is a key factor in mould formation. Homes and interior rooms have plenty of sources of moisture.

    The growth of mould fungi is mainly determined by four factors: moisture, nutrient supply, temperature and the pH value of the substrate.

    Tips & tricks for avoiding mould in your home or house

    Protection from mould generally entails: 

    • Avoiding moisture and damp building components

    • Ventilating properly

    • 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 a window.
    • 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.


    How to remove and fight mould effectively

    If you detect mould in your home, e.g. as mould stains, you should act as soon as possible and remove the stains. Mould 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 the coats of paint, but always includes fighting the causes and eliminating the damage.

    Mould remediation with the KEIM Mycal System

    KEIM's Mycal mould remediation system with its special anti-mould wall paint to eliminate or prevent mould infestation includes a variety of intelligent solutions, making it simple and easy and, above all, safe to handle every mould problem. The system consists of various healthy, mineral, individual products that can be put together in various combinations for specifically adapted remediation options. This is in any case the best choice for living without mould in the long term.
