What is the importance of cleaning a chalked surface before painting?

Cleaning a chalked surface before painting is crucial because it improves paint adhesion. A chalked surface typically has a powdery residue that can weaken the bond between the paint and the surface. This residue may lead to poor adhesion, resulting in flaking or peeling over time. By thoroughly cleaning the surface, you remove contaminants such as dust, dirt, and chalk, allowing the paint to properly adhere to the underlying material.

This process not only helps ensure that the paint will stick effectively but also enhances the longevity and durability of the paint job. Good adhesion is essential for maintaining the integrity of the finish, ultimately leading to a more successful painting project.
