Keim Lotexan is a clear dust suppressant and water repellent siloxane based treatment for use on alkaline mineral substrates such as concrete, brickwork and new cementitious and lime based renders
For mineral substrates having a lower alkalinity, such as weathered natural stone, Keim Lotexan N was developed as a dedicated generic variant.
When applied Keim Lotexan/N soaks into the substrate and, having a very small molecular size, it coats the pores of the mineral structure. A chemical reaction takes place converting the siloxane into a silicone layer on the pores of the substrate which provides water repellency while maintaining the vapour permeability.
Keim Lotexan is a beneficial alternative to silicone which has a much larger molecular size and tends to fill the pores rather than coating them, reducing breathability and leaving a shiny appearance on the surface.
