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 Cleaning Cream is made from natural, renewable raw materials and it is suitable for removing scaling and efflorescence quickly and effectively from mineral substrates. It also cleans many other materials and surfaces and can be applied on Façades, clinker, paving stones, and natural stone.
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 liquid and can therefore be sprayed onto the façade or alternatively brush applied.
Always adhere to the specifications in the respective Technical Guidelines.
