Facade paints

High quality topcoat paint based on specially modified potassium water glass intended for applying paint coatings outside buildings. It is especially recommended for primary and renovation painting of mineral substrates and for use on damp surfaces in historic buildings. It is applied exclusively on mineral substrates (i.e. concrete, traditional lime renders, lime-cement renders, cement renders, as well as thin coat mineral and silicate renders). It makes up a completely mineral, high vapour permeable coating (Sd< 0.01 m) allowing for free evaporation of moisture from the walls and at the same time due to the application of hydrophobizing substances, it efficiently protects the facade from precipitation. Because of high alkalinity it is naturally resistant to algae and fungal growth. The amount of organic substances in the paint is below 5% acc. to DIN 18 363.

Product advantages

• Product has been classified as mineral
• Good coverage
• Exceptional vapour permeability
• High adhesion to substrates
• Natural resistance to algae and fungal growth
• For use on mineral substrates
