All white – For the interior of the new building, a biocide-free and thixotropic white mid-coat wood stain was applied, certified according to EN 71-3. The product has high UV light resistance and a strong white point in order to reduce the yellowing of the used spruce wood elements. The specialist planners also chose white as the dominant façade colour for the exterior. In order to protect it from the weather, a special build-up of the individual protective layers was necessary. For this purpose, the building surface was treated with a wood preservative primer for preventive protection against blue stain (tested according to EN 152) as well as against wood-destroying fungi (tested according to EN 113). Furthermore, a specific insulation based on cationic resins was applied to prevent yellowing and bleeding of the resins. A white weather protection paint was used for the final coat, while a medium-layer wood stain with high resistance to UV light was chosen for the red larch façade behind the white lattice cladding.
