One、Advantages and disadvantages of painting wood with a brush
Applying putty powder with a brush results in a flat surface, but poor brushwork can leave brush marks.
The advantages of applying wood paint with a brush compared to spraying include a slower application process, but it provides a textured finish and facilitates easy repairs.

The disadvantage of painting is that the rolling effect on large surfaces differs from the brushstrokes in the light cove, resulting in a noticeable difference in texture. However, when painting, the water-to-paint ratio must be controlled between 20% and 30%, and not exceed 35%. Exceeding this dilution ratio can easily lead to peeling and/or bottoming out issues after painting.
II. Advantages and Disadvantages of Spraying Wood Coatings
Using a spray gun for application is a cost-effective option, as spray painting equipment can be expensive. This application method results in a smooth, flawless surface with excellent hand feel and fullness, making it a highly desirable outcome.
Spray painting offers advantages such as fast application and good smoothness. However, it has drawbacks, including significant wood finish loss and difficulty in subsequent repairs. This is because, after repairs, it is unlikely that workers can reapply spray paint, and the finish achieved by brushing will inevitably differ from that of spraying.
III. Conclusion
Applying wood paint with a brush or sprayer each have their own advantages and disadvantages. It is recommended to consult with a professional contractor to determine the best method for your specific project.
