Sivupinnoille

Sivupinnoille is a Finnish technical term used in carpentry, cabinetry, and furniture finishing to indicate that a surface treatment, veneer, laminate, paint, or other coating should be applied to the side surfaces of a component. The phrase combines sivu, meaning side, with pinnoille, the allative form meaning onto the surfaces, and it appears in instructions and specifications to distinguish side-face finishing from treatments applied to the top, bottom, or front faces.

In practice, sivupinnoille may refer to applying a veneer or laminate to the lateral faces of panels, or to applying protective or decorative coatings to those sides. The instruction often accompanies details about material thickness, adhesive types, and edge handling, since side surfaces can require different alignment and finishing steps compared with other faces. Sivupinnoille is typically used in formal production documentation, CAD drawings, and supplier catalogs rather than in everyday language.

The term is most common in Finnish-language professional contexts and may be rendered in translation as “applied to the side surfaces” or “side-surface finishing.” It helps organize the sequence of manufacturing steps by clarifying which faces are being treated. While widely understood within the industry, sivupinnoille is rarely used outside technical materials, and readers new to Finnish woodworking terminology may encounter it primarily in manuals or project specifications.
