The definition of wood veneer is real wood that has been cut or peeled into very thin sheets. Veneer is usually adhered to larger, flat pieces of solid wood to create an attractive and economical final product. Many types of veneer wood range in quality but are often made from high-grade logs. Substrate is the wood or other material to which veneer adheres. Veneer can be adhered to several different substrates using various products, including glues and contact adhesive. When applying veneer to a project, it should always be cut a bit larger than the substrate it is attached to and trimmed down to size. Veneer can be very useful as a finishing layer for a curved project since it is flexible.
