Great paint results always start with prep. Before any roller touches the wall, patching, sanding, and surface cleaning should be completed correctly.
A proper prep sequence includes repairing cracks and nail pops, sanding rough areas, and removing dust so primer and paint can bond evenly.
Skipping prep often creates flashing, texture differences, and short paint life. Professional prep work protects your investment and improves final appearance.
If your walls have older repairs or water spots, ask for a dedicated spot-prime step before full painting begins.
