Ready-to-use paste-like structural plaster based on silicone resin. Recommended as a finish for ThermoELF façade thermal insulation systems, especially with the use of mineral wool boards, and for such prepared surfaces as concrete or mineral plasters with sufficient load-bearing capacity. Can be used on existing water-dispersed silicate paints that hold well.
The surface must be clean, dry, smooth, load-bearing and meet the conditions of preparation in accordance with the requirements.
Contaminants and substances that adversely affect adhesion must be removed and bumps or chips smoothed with suitable materials, such as "KlebeMasse KM 193". Highly absorbent surfaces must be primed with materials such as UniGrund fixing primer or GrundKonzentrat primer concentrate. Glossy surfaces, such as concrete, and surfaces made with Klebe -und ArmierungsMasse KM 195 must be primed with Silikon-PutzGrund 118. In order to create a uniform optical effect and improve adhesion on a prepared basis, it is recommended to use Silikon-PutzGrund 118 primer, tinted in the color of the plaster.
Silikon-Fassadenputz K15 ready-to-use dispersion plaster. Mix the contents thoroughly with a low speed stirrer. If necessary, to adjust the consistency, the plaster can be diluted with water, but not more than 2% by weight. Add water to each bucket, in equal amounts, to avoid color differences. At the mechanized drawing it is necessary to be guided by the instruction on operation of the equipment.
Apply an even layer with a stainless steel trowel or a machine for spraying fine-grained plaster, remove excess, leaving a layer the thickness of the grain. Immediately after that, rub the surface with polyurethane, polystyrene or wooden grater, making uniform movements on the surface.
During application, and during drying, the ambient air temperature and the substrate must not fall below +5°C and rise above +30°C. Do not apply in direct sunlight, strong wind, fog, high humidity or when waiting for frost in the coming days.
