Climatic influences and the resulting penetration of moisture into the substrate often lead to damages to the façade. In order to protect facades made of mineral or cementitious building materials, impregnations are used which 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
KOSTER 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.
KOSTER 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.
KOSTER Siloxan in contrast is a liquid and can therefore be sprayed onto the façade or alternatively brush applied.
Always adhere to the specifications in the respective Technical Guidelines.
