Product Description

Farbius® exterior paint is a full-value silicone resin paint with a high percentage of silicone resin based on modified silicone resin emulsion. Farbius® is also highly suitable to be used as an equalizing paint for mineral based Farbius® Energy Saving Finishing Coat and Farbius® Restoration Render. Its special ceramic microspheres provide an ideal temperature and humidity balance. These properties result in a positive energy saving effect. A wide range of color options is available from the Farbius® color palette or can be mixed at your individual request.

Exposure to artificial weathering

Stress by reflecting UV radiation and water according to DIN EN ISO 11507: Farbius® is highly UV-A Resistant. After 1000 hours of artificial weathering (Exposure to UV-A radiation and water) the approved Farbius® coating shows a very good resistance (no color change, no delamination, no blistering, no rust, no cracking, no peeling, low chalking).

Determination of radiation-related parameter in accordance with DIN EN 410 and DIN EN 12898 (absorptivity and emissivity): The measurement is carried out on a Perkin-Elmer-Grid spectrometer Lambda 19 with 150mm integrating sphere. A spectralon is used as calibrated reference standard. The emissivities are determined based on DIN EN 12898, issue April 2001: the normal overall reflectivities Rn are calculated at a temperature of 283 K. The measurement is performed in the wavelength range between 2.5 and 25 μm on a FTIR-spectrometer Vertex 70 from Bruker Optics with intergrating sphere. Gold is used as a reference material.

Fire behavior according to DIN 4102, part 1:

Farbius® meets with a maximum application rate of 400-g/m2 applied to solid mineral surfaces, the requirements of class A2 for non-combustible materials according to DIN 4102, Part 1 (May 1998). Testing institute Hoch, Lerchenweg 1, D -97650 Fladungen, certificate PZ-Hoch-131357 valid until 30/09/2018.


Farbius® is a solvent-free facade paint with mineral-based structure. It can be applied on Farbius® Finishing Coat or Farbius® Wall Filler, all plasters and mineral subsurfaces. Farbius® is highly suitable to be used as an equalizing paint for Farbius® mineral plasters and Farbius® -262. Other areas of application include restoration render on all subsurfaces that have been painted as well as old insulation veneers.


Farbius® is ready to use. It can be diluted with up to 5% clean water for primer and intermediate coating and up to 2% for final coating. Depending on the type of substrate, a primer with Farbius® may be required. Farbius® can be applied evenly as equalizing paint in the same hue as the plaster 72 hours after completion of the mineral based Farbius® Coat through rolling over the substrate with a suitable paint roller, a brush or appropriate spraying tools. The nozzle size should be between 0.036 "(0.91 mm) and 0.045" (1.04mm). The substrate must be dry, firm, must be free from dust and loose parts or separating agents (e.g., forming oil). The object and ambient temperature must not go below +5 °C and above +30 °C. Drying time is 12 hours under normal conditions (+20°C/65% relative humidity). Lower temperatures and higher humidity will require more time.

Useful Hints

Do not process in direct sunlight, rain or higher air humidity. Please request further assistance when in doubt about processing, subsurface or constructional features. In all other respects the provisions of the current standards apply.

Special Notes

Do not mix with other types of materials. Stir well before processing. Cover adjacent components well to avoid splashing. Clean Tools thoroughly with water after use. Containers must be completely emptied and recycled.


The use of proven and continuously tested raw materials guarantees consistently high quality. State of the art manufacturing facilities ensures consistent product characteristics. Product quality control is conducted constantly in the factory.


Depending on the type and porosity of the substrate approximately 0.2 - 0.3 l/m². Caution: Rough surfaces can increase usage. Precise amounts are determined by testing on sample plots.

General Information

Farbius® coating system is formulated to prevent algae and fungi. Whether or not and to what extent algae and fungi occur depends on local and prevailing conditions. Through its optimal surface structure, Farbius® makes the surface dry and thereby works against the formation of algae and fungi to a large extent.
