The perfect violin paint should have four functions: protecting the surface, preserving the wood, decorating the appearance and improving the quality of the violin. When a violin is first made, it sounds strong and full before it is painted, but if it is not painted all the time, the tone and volume will deteriorate in a short time. The violin color and primer on the white violin is just a protective layer that will not penetrate into the wood. In addition, the internal violin is not treated, the atmosphere and various environmental conditions will affect it through the sound hole and cause decay. Only the exterior of the violin is painted, and the paint film becomes a hard or semi-hard surface when dry, making the exterior density and elasticity of the board different from that of the interior. There are some paints that are used as pretreatments. The same effect can be applied to the inside and outside of the wood and even to the center.
The physical structure of wood is more complex, with hollow Spaces between the fibers and in the various pipes, and it is necessary to make them more coherent and consistent. The chemical composition contained is also various, can affect the change of wood moisture content, the moisture content of the untreated wood is determined by the humidity in the atmosphere, the process of water loss, water absorption, to reach the balance continuously alternates. When wood dries, it contracts, when it absorbs water, it expands, and when it contracts and expands, the direction across the grain is greater than the longitudinal direction. So wood needs to be pretreated to homogenize and reduce moisture absorption.
