Rappaukselle

Rappaukselle is a term referring to the process of applying render or plaster to a surface. This can be for decorative, protective, or structural purposes. The material used for rappaukselle is typically a mixture of cement, lime, sand, and water, though additives can be included to modify its properties.

The application of rappaukselle involves several stages. First, the surface must be prepared, which may include cleaning, dampening, or applying a bonding agent. The render is then mixed to the correct consistency and applied in one or more coats. The first coat, known as the scratch coat, is often scored to provide a key for subsequent layers. Following coats are built up to the desired thickness and finished to achieve the intended texture and appearance. Common finishes include smooth, textured, or patterned surfaces.

Rappaukselle is a versatile technique used on a variety of substrates, including brickwork, blockwork, concrete, and insulation boards. It is commonly employed in both new construction and renovation projects for both interior and exterior walls. The rendered surface can then be left as is, painted, or limewashed. The durability and aesthetic appeal of rappaukselle make it a popular choice in many architectural styles.
