Video: Insulating Paint Against Mold
There are different standards for almost everything in construction, only not for the health protection of the residents.
Mineral paints consist of potassium silicate, mineral pigments and fillers and contain no problematic ingredients such as solvents, plasticizers or preservatives.
The indoor air is often more polluted than the outside air on a busy street. Wall paints and varnishes are also possible emission sources. They often contain undeclared plasticizers or preservatives such as isothiazolinones that escape over long periods of time and thus pollute the room air. Each of these substances can cause allergic reactions or trigger irritation of the mucous membranes, fatigue, headaches and poor concentration.
What is a healthy indoor climate? “It depends on the factors of temperature, humidity and air exchange,” explains interior designer Mathias Rathke. “But emissions from building materials and furniture can also affect the quality of the indoor air and thus the well-being. This presents us with challenges, particularly in modern, highly insulated buildings without controlled ventilation. I recommend my builders to counteract this with vapor-permeable, pollutant-free coating systems."
Principle of silicification
Diffusible mineral colors only contain components that are harmless to human health and the environment. And this from the silicate principle of silicification: The binding agent forms an insoluble bond with the substrate in a chemical reaction and thus remains highly diffusible for water vapor. This principle was invented and brought to market maturity by the skilled potter and tinkerer Adolf Wilhelm Keim. In 1878 he laid the foundation stone for the Keimfarben company with the first two-component silicate paint. In the following decades, the company rose to become the market and competence leader in mineral building protection.
Biosil has been the first silicate interior paint suitable for allergy sufferers on the market since 1983: without the addition of preservatives, plasticizers and solvents and highly diffusible. For this, the company received the TÜV environmental seal in 1998, followed in 2003 by the certificate "suitable for allergy sufferers" (IUG). Regular checks by independent institutes confirm product safety. Biosil was the first manufacturer to be awarded the "natureplus" quality mark. This seal of approval places much stricter requirements on construction products than the “Blue Angel” and is intended to provide consumers and construction professionals with guidance on how to identify the best proven products for sustainable construction on the market.
Not only Biosil, but also all other interior wall paints by the manufacturer are ecological. The ability to diffuse ensures that the wall absorbs moisture, releases it when necessary and that no condensate forms in the wall structure. This means that the surface moisture that molds need for their growth is missing. In addition, the natural alkalinity of the silicate paints has a mold-inhibiting effect.
