Gyppirappaus

Gyppirappaus is a Finnish term that refers to a method of applying gypsum-based plaster to walls and ceilings. It is a traditional and durable finishing technique that has been used for centuries in Finland and other Nordic countries. Gyppirappaus is known for its smooth surface, breathability, and resistance to cracking.

The process involves mixing gypsum plaster with water to create a workable paste. This paste is then applied in layers to the prepared surface, typically lath or brick. Each layer is carefully troweled smooth, allowing for significant drying time between applications. The final coat is often polished to achieve a very fine and even finish. Gyppirappaus can be left as is, painted, or decorated with various finishes. Its natural composition makes it a sustainable and environmentally friendly building material. The skill of the plasterer is crucial to the quality and longevity of gyppirappaus. Older buildings often showcase exquisite examples of this craft.
