brush marks

Brush marks are visible streaks or lines left on a painted surface by the bristles of a paintbrush during application. They can occur when paint is applied unevenly, when the paint is too thick or drying too quickly, or when low-quality brushes or improper technique are used. In professional painting, brush marks are generally considered undesirable, as they can affect the smoothness and overall finish of the surface. Skilled painters use proper tools, techniques, and paint formulations to minimise or eliminate brush marks for a high-quality, uniform finish.
