Keim Mineral Paints originated in Bavaria in 1878 and are now used extensively around the world. The system was developed by A.W. Keim to reproduce the appearance of lime fresco finishes which were able to withstand harsh weather conditions.

Keim Soldalit-ME – Exterior Photocatalytic Mineral Paint

KEIM Soldalit-ME offers sustainable exterior protection for buildings with the environmental benefit that it helps to degrade nitrogen oxide pollutants from the air we breathe.

Photocatalytic mineral paints use light energy to neutralise pollution. Whilst mineral paints already contain only environmentally friendly and sustainable materials, titanium dioxide is also added as a catalyst which enables the photocatalytic reaction. The catalyst is not used up by the reaction and will continue to react for the life of the paint.

The photocatalytic reaction converts Nitrogen Oxides and other harmful pollutants including formaldehyde and acetaldehyde into harmless nitrates. The reaction also helps to breakdown organic material and contaminants, keeping surfaces cleaner. When titanium dioxide is used in conventional paints it can breakdown the organic paint itself, reducing the lifespan of such paints.


Keim Soldalit-ME has been used at the following projects:
