Lakkauspintaa

Lakkauspinta, or lacquered surface, refers to a coating produced by applying lacquer to a substrate to create a hard, protective finish. The resulting surface is typically smooth, durable and can be either clear or pigmented, often with a high gloss. Lakkausta käytetään sekä puu- että metallipinnoilla sekä monissa muissa materiaaleissa.

Coatings used as lacquer consist of a film-forming resin dissolved in a solvent. Common resins include nitrocellulose, polyurethane, acrylic and melamine-formaldehyde, with pigments added for color. Modern lacquers can be solvent-based or waterborne, the latter reducing volatile organic compound emissions. The thickness of the cured film and its gloss depend on the formulation and the application method.

Surface preparation is essential for a good lakkauspinta. The substrate must be clean, dry and free from defects. It is usually roughened, primed or sealed, and then coated with one or more layers of lacquer by spraying, dipping or brushing. Each layer is dried or cured before applying the next. Final finishing may involve polishing or light sanding to achieve the desired smoothness and gloss.

Properties and care: a lakkauspinta typically offers good abrasion and chemical resistance and forms a moisture barrier. However, it can be sensitive to solvent attack and may crack if the substrate moves or if there is poor preparation. Maintenance involves gentle cleaning and, if damaged, repair through sanding and re-coating.

Common applications include furniture, musical instruments, cabinetry, automotive parts, metal hardware and decorative items. Lakkaus provides both aesthetic appeal and surface protection, balancing appearance with functional durability.
