Climatic influences and the resulting penetration of moisture into the substrate often lead to damages to the façade. In order to protect façades made of mineral building materials, impregnations are used to make the surface water repellent. These hydrophobic agents penetrate deeply into the substrate, and dry without leaving residues, so that the visual appearance of the façade is not affected by the impregnation.

Protecting façades made of mineral building materials

1 Surface protection
KÖSTER Façade Cream
KÖSTER Siloxan

KÖSTER façade protection systems prevent masonry and concrete from liquid water ingress (rain or splash water, condensate), but at the same time, water vapor is still able to escape from the façade. That way, long term moisture damage can be avoided.

KÖSTER Façade Cream is a solvent-free pasty hydrophobization material. It is applied as a film using a roller or brush and penetrates deep into mineral substrates.

KÖSTER Siloxan in contrast, is a hydrophobization liquid and can therefore, be sprayed onto the façade or alternatively brush applied.

Always adhere to the specifications in the respective Technical Guidelines.
