Skipping the sanding step after priming often leaves a slightly rough, textured, or chalky surface filled with raised fibers, dust nibs, and minor imperfections. When you apply your final topcoat over unsanded primer, these flaws remain visible, resulting in a gritty texture and a less-than-professional finish. Lightly sanding ensures an ultra-smooth base that maximizes the gloss, uniformity, and overall tactile quality of your final painted walls or woodwork.
