OVERVIEW OF KEIM WATER REPELLENTS & DUST SUPPRESANTS

KEIM Lotexan is a clear, siloxane based water repellent and dust suppressant  treatment for use on alkaline mineral substrates such as concrete, render and brickwork. 

When applied onto mineral surfaces, KEIM Lotexan soaks into the substrate and, having a small molecular size, coats the pores of the mineral structure without blocking them. A chemical reaction takes place, creating the water shedding properties of the siloxane, imparting excellent water repellence while maintaining moisture vapour permeability through the open pores.

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 often sitting on the surface, creating a glossy or ‘wet look’ effect.

KEIM Silan 100 is a waterproofing primary coat which can be used as a hydrophobic impregnation for mineral substrates prior to the application of KEIM Mineral Paints.  KEIM Silan 100 can only be applied onto bare surfaces. 

KEIM Silan 100 also has the ability to resist the passage of some waterborne salts and can be used for this purpose.
