The silicate paint is usually used only by painter professionals, do-it-yourselfers seldom rely on it. This is probably due to the fact that this color is strongly alkaline and by far not on any surface, and they are often sought in the hardware store in vain. Preservationists, however, swear by this coating: Why, we will see below!
Silicate paint: a facade paint with special properties
The high pH value of the silicate paint also has its advantage: The coating has a mildew and germicidal effect, so that the wall behind it is protected to a certain degree against the colonization of microorganisms, fungi and algae. There are also other interesting benefits:
- Silicate paints and their pigments are colorfast and lightfast. Schw Sulfur-containing exhaust gases can hardly affect the coating.
- The coating material does not stick to the surface, but a chemical reaction takes place (silicification).
- The wall remains permeable with its new coating.
- The color has a moisturizing effect, which is especially important indoors.
- Silicate paints have an extremely long shelf life.
- The changing weather does not bother them.
- Natural colors without artificial additives are suitable for allergy sufferers.
- These versatile "talents" make the silicate paint a versatile product that scores not only on the facade, but also indoors. How do these qualities come about?
A look inside: What are silicate paints made of?
Silicate paints are therefore excellently suited for painting facades, because they consist of the binder potassium silicate glass and contain mineral pigments. These materials are naturally characterized by their longevity. Feste The solid silicification of potassium silicate glass with mineral surfaces causes the silicate paint to merge with the façade, so to speak, and can only be removed again by knocking off the plaster.
However, this type of color holds only on said mineral substrates, other surfaces offer it no support. So-called dispersion silicate paints are an exception to this rule because they were mixed with plastics.
Optical effect on the façade: Silicate paint in a pleasant matt look
The silicate paint is similar in many details to the lime paint, and the look is quite similar. A dried silicate coating has a matte surface and a slightly iridescent tint that looks natural and aesthetic.
