When treating the base layer, in addition to cleaning the surface debris of the base layer, local putty embedding should be carried out, and sandpaper should be sanded along the wood grain. Before painting the surface layer, use paint chips (shellac paint) to seal the knots with large color differences and wood resin. Dry oil or cleaning should be applied to the base layer. When spraying the dry oil layer, all parts should be sprayed evenly without leakage. After the base oil is completely dry, apply the first coat of putty. After drying, sand it with manual sandpaper, and then top up with high-strength putty. The putty will not fall when you pick it up. When spraying the top layer of paint, it should be sanded with fine sandpaper first.
Notes:
The base treatment should be carried out according to the requirements for display cabinet production, [because the painted display cabinets have a variety of effects, such as matt/semi-matt/bright/open, etc.] to ensure the production effect and achieve the surface paint The spraying and design effects are the same.
Before spraying, the surrounding environment should be cleaned to prevent dust from flying and maintain a clean spraying environment.
Because paints are toxic to a certain extent and have a strong irritating effect on the human body and respiratory tract, attention must be paid to ventilation and self-protection during construction.
