I. Spraying
1、Advantages and disadvantages
The spraying effect is generally good, but sometimes it can result in the appearance of particles, and it is not easy to repair.
2、Construction Method
Pour the water-based wood paint into the sprayer. Then, apply the paint in a left-to-right direction, followed by a right-to-left direction, creating a single coat. When spraying, depress and release the trigger at the beginning and end of each pass, and repeat this process until the desired coat is applied. The entire process should be smooth and consistent.
3、important Notes
To ensure stable operation, the spray gun should have a consistent spray pattern with an interval of 40-60 mm between the nozzles. The spray gun should be moved in a regular pattern, and the application location should maintain consistent color and uniform thickness. It is also important to avoid overspraying and dripping.
Two. Brushing application
1、Pros and Cons
Brushing is a highly efficient method for applying wood coatings, although it requires more time, it delivers excellent results.
2、Construction Method
Apply paint with a brush on a clean and rough surface, moving the brush back and forth to smooth the surface. Then, dip the brush into the paint can and hold it firmly. Use wrist and arm movements to control the brush, while simultaneously moving the body for support.
3. important Notes
Due to the fast drying speed of water-based wood paints, each coated surface should be brushed as many times as possible to avoid lap marks. When applying paint manually, it is necessary to start from one point and apply the paint in the correct order to prevent overspraying or uneven application.
III.Roller coating
1、Advantages and disadvantages
Generally, factories opt for roll-on application. While not the most effective method compared to others, it is a relatively cost-effective construction method.
2、Construction Method
The material will be conveyed between the rotating coating roller and the infeed roller, and the machine will automatically perform roller coating.
3. important Considerations
To avoid roller marks during spraying, the wrapped width should be 1/4 of the roller length. Typically, spraying is done in two coats. When spraying water-based wood coatings in summer, a two-hour interval is required before applying the second coat. In winter, a longer interval is needed.
