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.
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.
