Answer:
Sprung molding is a technique used to apply molding to a curved or irregular surface by manipulating the molding material to conform to the shape of the surface. Instead of cutting the molding to the exact shape of the surface, the molding is carefully bent or flexed to fit the curve, similar to how a spring is squeezed or expanded to fit into a specific space.
This method can be employed for various types of moldings, such as crown molding, baseboards, or chair rails, and allows for the installation of decorative trim on curved walls, archways, or other non-linear architectural elements.
To achieve a proper fit, the molding material, typically made of wood or flexible polymer, is heated or soaked in hot water to increase its pliability. Once it becomes more malleable, it can be bent or curved by hand or with the help of specialized tools, such as heat guns or steam boxes.
The sprung molding is carefully positioned and pressed onto the curved surface, ensuring that it conforms to its shape. The tension or flexibility of the molding material allows it to hold its curved position once properly installed.
This technique requires precision and craftsmanship to achieve seamless and smooth transitions between straight and curved sections of molding. It may also involve the use of adhesives, nails, or other fastening methods to secure the molding in place.
Sprung molding offers an aesthetically pleasing solution to create decorative and architectural details on curved surfaces, adding elegance and character to interior spaces.
