Multi-purpose, silicate exterior paint on a sol-silicate binder basis (combination of silica sol and water Glass) for organic, mineral and mixed substrates. The sol-silicate paint KEIM Soldalit is water-repellent, highly water vapour permeable, lightfast, UV-stable, extremely resistant to weathering with minimal soiling tendency. KEIM Soldalit combines all the advantages of a classical silicate paint with the application range of an organically bound paint. Organic content < 5%.
