Laatikkomassa

Laatikkomassa is a Finnish term that translates literally to "box mass" or "box compound." It refers to a type of composite material used primarily in construction, particularly for interior walls and ceilings. Its composition typically includes a binder, such as cement or gypsum, mixed with aggregates like sand, perlite, or vermiculite. These ingredients are combined to create a lightweight, workable material that can be applied in a thin layer.

The primary function of laatikkomassa is to create a smooth, monolithic surface for finishing. It is often applied over substrates like concrete, brick, or prefabricated panels. Its properties allow it to fill minor imperfections and create a level base for subsequent decoration, such as painting or wallpapering. It can also provide some degree of thermal and acoustic insulation due to the inclusion of lightweight aggregates.

Laatikkomassa is known for its ease of application, often spread with trowels or specialized tools. Once dry, it can be sanded to achieve a very smooth finish. While not designed for structural purposes, its use contributes to the overall finish and aesthetic quality of interior spaces. It is a common material in Finnish building practices, valued for its practicality and performance in achieving seamless wall surfaces.
