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.

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 variety holds only on said mineral substrates, other surfaces offer her no support. So-called dispersion silicate paints are an exception to this rule because they were mixed with plastics.

Optical effect on the facade: Silicate paint in a pleasant matt finish
