The coating process of solid wood white embryo is an art in the hand

The white embryo of high-grade solid wood furniture must be brushed with thin shellac varnish; when sanding, it must be laid out and grind carefully until it is thoroughly polished; brush the water color between the coatings to make the color bright; repeated inlay putty to ensure the smooth surface of the coating. The thickness of the paint film must be guaranteed; the flatness of the paint film must be high; all painted parts are polished. In addition to the above-mentioned finishing requirements, shellac varnish is sometimes wiped, and the coating is stripped to ensure the uniformity and clarity of the paint film; use the simulated wood grain method to make the ordinary texture material reach the precious wood texture; sometimes it needs to be corresponding Improve certain indexes of the physical and chemical properties of the paint film to achieve high-level finishing quality. High-end furniture white embryos must meet the following prerequisites: 1. The wood has a beautiful natural texture; 2. The structure is unique, strong and beautiful; 3. The wood is dry and finely processed; 4. The finishing process is reasonably formulated according to the quality requirements of the paint film.

Wait, it should be flat and filled. Dry for 15min. The color of the putty should be determined according to the color of the paint film. 3. For sanding, use No. 1 wood sandpaper to grind the corrugated corners, carefully polish the surface along the grain of the wood, sand to remove the wood hair, and smooth the putty. 4. Wipe the old powder with water (calcium carbonate) and add water to make it into a slurry, and then gradually add the required pigments to make the pigments evenly dispersed. Paint and rub with bamboo flowers by hand. Dry for 1-2h. 5. Brush thin oil (or shellac varnish) with a ratio of phenolic novolac and gasoline at a ratio of 3:7 and mix well.

Use a horn scraper to fill the surface of the coating. It must be batched and scraped clean to prevent missed batches, omissions and putty deposits, otherwise the wood grain is unclear and it is not easy to sand. Dry for about 4-8h. 8.
