Surface Protection

 

The KEIM range of water repellent and dust suppressant products provide clear surface treatments for all mineral substrates. 

Whether it is protecting the substrate from water penetration or to reduce a dusty appearance, KEIM products provide treatments which are highly moisture vapour permeable and long lasting, with minimal effect to the appearance of the surface itself.

OVERVIEW OF KEIM WATER REPELLENTS & DUST SUPPRESANTS

KEIM Lotexan®

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 Fixativ

KEIM Fixativ is a silicate binding agent and dust suppressant which reacts chemically to consolidate the surface. KEIM Fixativ is water vapour permeable and is suitable for external and internal use on surfaces with light chalking and dusting. 

Colour shade
Clear

Application
Brush or airless spray

Consumption
Approx. 0.1 l/m2

Packaging
4 lt containers

KEIM Silan-100

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.
