KEIM Lotexan-N

KEIM Lotexan N is a clear, siloxane based water repellent and dust suppressant treatment for mineral substrates which have a low alkalinity, such as weathered natural stone. 

Please note that if your stonework has lime pointing then we would instead recommend KEIM Lotexan for higher alkaline surfaces.

Alternative option

KEIM Ecotec

KEIM Ecotec is an environmentally friendly, solvent free, colourless water repellent and dust suppressant.  KEIM Ecotec is a concentrated hydro-phobing silicone micro-emulsion, diluted with water, which reduces water absorption.
