Facade paints are coating materials specially developed for exterior use, containing mineral or organically bound pigments and based on various binder types such as silicone resin, silicate or dispersion. They must meet high requirements for water repellency, water vapour permeability and light fastness, while protecting the substrate and permanently resisting weathering influences such as rain, frost and UV radiation. Modern facade paints often contain biocidal additives to prevent algae and fungal growth. Product selection depends on the substrate (render, concrete, ETICS top coat) and the desired aesthetic outcome. Thorough substrate preparation and adherence to correct application temperatures ensure long-term coating quality.
