How long does it take to learn wall painting?

Two to three months. If you have a certain painting foundation, it only takes two months to master the basic wall painting skills. However, for those who have no foundation at all, it is suggested to learn the basic knowledge of painting such as basic sketch and color first, which can lay a solid foundation for the subsequent study of wall painting. The foundation of wall painting is drawing foundation such as sketch and color, just like internal work. If you don't have a solid painting foundation, just learning the skills of wall painting is like having only a flower shelf and no real strength. So for beginners, it takes three months to complete the basic courses and the professional courses of wall painting.
