Climatic influences and the resulting penetration of moisture into the substrate often lead to damages of the façade. In order to protect facades made of mineral building materials, impregnations are used which make the surface water repellent. These hydrophobing agents penetrate very deeply into the substrate and dry without leaving residues so that the visual appearance of the façade is not affected by the impregnation.
KÖSTER façade protection systems prevent masonry and concrete from liquid water ingress (rain or splash water, condensate) but at the same time they guarantee that water vapor is still able to escape from the façade. That way long term moisture damages 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 the façade.
KÖSTER 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.
