The castle of the Princess of Solms-Hohensolms-Lich is located in the old part of the small town of Lich in Hesse. The late Renaissance palace was originally a castle surrounded by moats and was structurally altered in the Baroque style in the 18th century.» More about Schloss Lich
Project Example Schloss Lich
As part of thorough renewal of the render, damage to the façade - especially extensive render damage, caused in the base area of the walls by high salt exposure - was to be repaired and the severely weathered and dirty oil coating was to be replaced. The coating system specification was for particular weather-resistance and long system life. In addition, the system had to be extremely water-vapour permeable and have a matt, mineral look. The material and colouring were to merge to form a representative appearance, and weak mottling was explicitly desired as a vivid surface effect.
The Project Stages
The commissioned architects and painting contractor therefore chose the BEECK Pure Crystalline Finish paint system. Assisted by the BEECK consultant responsible, in the first step sample areas (so-called “Musterachsen”) were prepared in which to try out precise colour recipes and determine consumption values. Based on this the individual façade areas could then be redecorated in their new colour speedily - coordinated with construction progress - and with optimum material use.
The Paint System Used
For the façade renovation and colour redesign of Schloss Lich, a silicate glaze technique was used, which was applied with a pure silicate system (completely free from organic fractions).
The matt, slightly mottled surface of the new coating enhances the present day castle complex in true period style and maintains the listed building character of the property. The BEECK Pure Crystalline Finish paint system was also able to fulfil all the requirements that had been set by the owner and the building heritage conservation authority.

The Products Used
ETCHING FLUIDFluosilicate treatment of the render areas The aqueous-acidic solution was used to etch the calcareous sinter layers of the new plaster areas, and at the same time clean the remains of the weather, mineral old render and old coating. Any sinter skin - a glass-like and high-tension lime-binder concentration, which forms as a barrier layer when chemically reacting coating systems are used - was removed easily in this way.
FIXATIVEPriming The priming and consolidation of the mineral substrate was carried out with BEECK Fixative, potassium water glass, completely free from organic compounds. BEECK Fixative sets solely through silicification, which means it forms an inseparable unit with the microporous substrate and optimum building physics properties are achieved.
BEECK PURE CRYSTALLINE FINISH (white)Slurry primer coat BEECK Pure Crystalline Finish is a two-pack active silicate system made of potassium water glass and a mineral pigment-extender mixture. Due to silicification - the chemical reaction between the mineral substrate, pigments, extenders and potassium waster glass - the coating bonds with the substrate to form an inseparable unit and is therefore extremely resistant. Thanks to the application of a thin coating there are no excessive coat thicknesses. BEECK Pure Crystalline Finish can be reworked an unlimited number of times and thanks to its high alkalinity it counteracts dirt, mould and algae growth permanently. BEECK Quartz Filler was used as the filler. The fibre-reinforced primer coating levels out texture or structure defects, makes good render and hair line cracks and also acts as the glaze primer for the silicate glaze technique. A fine grit size (0.4 mm) produced a particularly deep effect of the finished coating.
BEECK PURE CRYSTALLINE FINISH (coloured)Intermediate and top coat The system was finished with a further coat of the transparently set two-pack silicate system applied using brushes, in order to achieve a slightly mottled colour design. Absolutely UV resistant inorganic mineral pigments were used for the colouring, including in full colour coating.
