sisälaasteet

Sisälaasteet, or interior plaster, is a building material used for finishing interior walls and ceilings. It typically consists of a mixture of lime, sand, and water, although modern formulations may include cement or gypsum for enhanced properties like faster drying times or increased strength. The primary function of sisälaasteet is to create a smooth, even surface that can then be painted, wallpapered, or left as a decorative finish itself.

The application process for sisälaasteet involves applying the material in one or more layers to the underlying substrate, such as brickwork, concrete, or plasterboard. Each layer is carefully troweled to achieve the desired thickness and smoothness. The traditional lime-based plasters are known for their breathability, which can help regulate indoor humidity and resist mold growth. They also offer a natural, aesthetically pleasing finish. Gypsum-based plasters are often preferred for their rapid hardening and smooth surface, making them ideal for quick renovations or new constructions. Cement-based plasters are generally used in areas where greater durability and moisture resistance are required, such as bathrooms or kitchens. The specific composition and application technique can vary based on regional traditions and desired aesthetic outcomes.
