Keim Natural Mineral Paints from Celtic Sustainables

TurretKeim Mineral Paints began their story in Bavaria in 1878, when A.W. Keim created the system to reproduce the appearance of lime fresco finishes with the ability to withstand harsh weather. The system is now used worldwide, and is available to order here in the UK and Ireland from Celtic Sustainables.


The Keimsystem is based on liquid silicate paint with ingredients including potassium silicate binder with inorganic fillers (feldspar) and natural earth oxide pigments. When the paint is applied to a mineral substrate, it forms a breathable coating which keeps rain from getting in and lets moisture out from inside. This is exactly how old buildings were designed to work, without using plastic-based paints which prevent any movement of moisture.


Keim Mineral Paints are natural, water-based, liquid silicate paints which when applied are extremely durable, giving a sustainable, colourfast, protective finish which works with the environment.

The system is so long-lasting that buildings painted over 100 years ago have still not needed redecorating. The Schweiz Town Hall in Switzerland was last decorated with Keim in 1891, and hasn’t needed another coat yet.


Keim is committed to making sure its products are derived from sustainable sources and made in the most environmentally friendly way. This fits perfectly with the Celtic Sustainables philosophy of providing eco-friendly products to maintain our buildings without causing harm to people or their environments.

Keim Mineral Paints are non-toxic and safe to use. Bound by water glass (potassium silicate), they are able to work without solvents, plasticisers, preservatives, or dangerous VOCs (volatile organic compounds). Even if you would like to redecorate, Keim coatings don’t need stripping and so avoid the environmental impact of paint removal. To repaint, simply wash with water and overcoat with a fresh layer of paint.
