Sanding after using Kilz primer is generally recommended if you are aiming for an ultra-smooth, professional-grade finish on surfaces like wood trim, doors, or cabinetry. Kilz primers can sometimes raise wood fibers or leave a slightly textured, chalky finish depending on the specific formula used. Lightly hand-sanding with fine-grit sandpaper after the primer has fully cured removes any imperfections, dust nibs, or roughness, ensuring your final topcoat of paint adheres smoothly and looks flawless.
