Description :

KEIM Lotexan is a siloxane based water repellent impregnation to reduce the water absorption of natural stone. Also used as a dust suppressant.

KEIM Lotexan penetrates into the pores of mineral building materials. Once the solvent has
evaporated, the active ingredient coats the walls of the pores and develops its water repellency by reacting chemically with the moisture normally present in the substrate and the atmosphere. This treatment does not seal the pores in mineral building materials, ensuring that its water vapour permeability remains practically unchanged.
