Yes, an undercoat is often needed when painting walls, especially if you're making a significant color change or painting over a dark or uneven surface. It helps improve paint adhesion, provides a uniform base, and enhances the durability and coverage of the topcoat. Using an undercoat can also reduce the number of topcoat layers needed, saving time and paint.
