The surface must be clean, dry, even, capable of bearing the load, and meet the preparation requirements. Highly absorbent surfaces should be primed with materials such as UniGrund sealing primer or GrundKonzentrat primer concentrate. Glossy surfaces, such as concrete, and surfaces treated with "Klebe-und ArmierungsMasse AM 195" adhesive-reinforcing compound, should be primed with "Silikon-PutzGrund 118." To achieve a uniform optical effect and improve adhesion on the prepared base, it is recommended to use "Silikon-PutzGrund 118" primer tinted to match the color of the plaster.
Material Preparation
"Silikon-Fassadenputz R20" is a ready-to-use dispersion plaster. Thoroughly mix the contents of the package using a low-speed mixer. If necessary, the plaster can be diluted with water to adjust the consistency, but no more than 2% of the weight. Water should be added to each bucket in the same amount to avoid color discrepancies. For mechanical application, follow the equipment operating instructions.
Note: Always consider the exact amount of water for consistency adjustment as indicated on the packaging.
