Wooden door painting: three-point paint and seven-point wood

<p>As a science, <a href="https://www.solidwoodendoor.com/product" rel="noopener noreferrer" target="_blank">wooden door</a> painting has endless exploratory nature like all other scientific fields. It is always in continuous progress and development.</p><p><br></p><p>As the base material of artificial board, such as medium density fiberboard, plywood, blockboard, etc., the base material is required to be flat and smooth, uniform in thickness, and free from warping, corner defects, delamination, bubbling and other defects. The color of the substrate should be consistent during transparent coating, and the color defects of the board surface should be controlled. Solid wood is used as a base material, such as solid wood board square lumber, solid wood finger joint lumber, etc., and its surface treatment is a special treatment based on normal mechanical processing. Generally include smoothing, sanding, surface cleaning, and wood wool removal. In view of the specific wood species and the surface condition after mechanical processing, it is sometimes necessary to remove the resin, bleach, and partially or completely repair the base material. The surface of the substrate should be carefully sanded to make it flat and smooth without any defects.</p><p><br></p><p>When veneer veneer is used for coating production, since the veneer is very thin (usually 0.2~0.3mm), the defects of the substrate can easily be reflected on the surface of the coating through the veneer, so the substrate must be strictly selected. The substrates with knots, cracks and resin capsules must be repaired, and all kinds of substrates should be strictly fine sanded before veneer veneer.</p><p><br></p><p>In modern wood finishing, the understanding of the surface quality of the substrate has changed from the past "three-point carpenter and seven-point oiler" to "three-point paint and seven-point wood", which shows that the modern coating industry has fully realized the surface quality of the substrate. The important impact on the final coating effect has changed the traditional wrong idea of relying on finishing coatings (paints) to cover up and make up for poor substrates.</p>
