High quality silicate-silicone decorative render in the form of paste, featured by high strength, excellent workability and good vapor permeability with silicone additives to increase water repellency. It is resistant to UV rays and atmospheric influences. Due to its characteristics, it is recommended for the restoration of old buildings and for the protection of cultural monuments.
Rajb – scratched structure, rille
Ful – full structure, kratz
PREPARATION AND APPLICATION
The substrate to which the render is applied must be solid, clean, dry and coated with BK-GrundSilicat primer. Mix BK-SilSi&Si before application and if necessary dilute with a small amount of water up to 1% (0.25l of water). The render is applied with a steel trowel with thickness of the largest grain. Depending on the desired structure, the render is then processed with a plastic trowel, namely: Full structure – structured in a circular pattern immediately after application; Reib structure – after application scratch by circular motions until the desired structure is achieved. It is necessary to work evenly and without interruption on continuous wall surfaces. See product datasheet for more detailed instructions.
It is necessary to equalize the material required for the continuous facade surface by mixing the contents of multiple bins.
From +15°C to +30°C, relative humidity max. 70 %. Do not work under direct sunlight, rain or strong wind. The facade must be adequately protected with mesh. High humidity and low temperatures can significantly extend the render bonding time.
Approx. 2. 4-3. 3 kg/m² depending on the structure and grain size.
SHELF LIFE AND STORAGE
12 months in original sealed packing. Store at temperatures from +5°C to +25°C, protected from direct sunlight and frost.
