Kipsipinnoitteet

Kipsipinnoitteet, commonly known as gypsum plaster or plaster of Paris, are a type of building material used for finishing walls and ceilings. They are composed primarily of gypsum, a naturally occurring mineral, which is heated to a specific temperature to produce anhydrous calcium sulfate. This powder is then mixed with water to form a paste that can be applied to surfaces.

The primary function of kipsipinnoitteet is to create a smooth, level surface ready for decoration, such as painting or wallpapering. They are known for their ease of application and quick drying times compared to traditional lime plasters. Kipsipinnoitteet can also contribute to fire resistance due to the water content within the gypsum crystals, which is released as steam when exposed to heat.

There are various types of kipsipinnoitteet available, including ready-mixed versions and those that require on-site mixing. Some formulations may also include additives to enhance properties like workability, setting time, or adhesion. These materials are widely used in both residential and commercial construction projects, offering a cost-effective and efficient solution for interior finishing. The application process typically involves spreading the material with trowels and then smoothing it to the desired finish.
