Viimeistelylaasti

Viimeistelylaasti is a Finnish term referring to a finishing plaster or render. It is a material used to create a smooth, even surface on walls and ceilings, typically applied as a final layer over a base coat of plaster or other substrate. This material is crucial for achieving a high-quality finish that can then be painted, wallpapered, or decorated.

The composition of viimeistelylaasti can vary, but it commonly includes cement, lime, sand, and various admixtures to enhance workability, adhesion, and durability. The fine aggregate size is a key characteristic, enabling the application of thin layers and resulting in a smooth surface texture. It is often applied by hand or with mechanical plastering equipment.

The primary function of viimeistelylaasti is to correct minor imperfections in the underlying surface, such as unevenness or small cracks, and to prepare it for decorative treatments. It provides a uniform and aesthetically pleasing background for interior and exterior finishes. The specific type of viimeistelylaasti used may depend on the intended application, environmental conditions, and desired aesthetic outcome. For example, exterior finishes might require different properties than interior ones regarding weather resistance and breathability.
