Kipsislaasti

Kipsislaasti is a Finnish term referring to a type of building material primarily composed of gypsum. It is a mixture, often a mortar or plaster, used in construction for various purposes. The main component, gypsum, is a soft sulfate mineral composed of calcium sulfate dihydrate. When mixed with water, gypsum undergoes a chemical reaction that causes it to harden, making it suitable for creating smooth surfaces or filling gaps.

The specific composition of kipsislaasti can vary depending on its intended application. It may include additives such as sand, lime, or other binders to modify its properties, such as setting time, strength, or adhesion. Kipsislaasti is commonly used for interior finishing work, including plastering walls and ceilings, creating decorative elements, and as a base for paints and wallpapers. It is known for its fire-resistant qualities and its ability to regulate humidity.

Historically, gypsum plasters have been used for centuries in construction. Modern kipsislaasti production typically involves calcining gypsum rock to form plaster of Paris, which is then mixed with other components to create the final product. Its ease of application and versatility have made it a popular choice in the building industry.
