    Ask any professional painter what the most important step in painting is, and they'll tell you: preparation. A beautiful, long-lasting paint job starts long before the first brushstroke.

    Surface cleaning removes dirt, dust, grease, and mildew that prevent paint from adhering properly. For exteriors, power washing is essential. For interiors, TSP (trisodium phosphate) or similar cleaners work well.

    Patching and sanding create a smooth, even surface. Holes, cracks, and dents must be filled and sanded flush. Glossy surfaces need scuffing to help new paint bond. Skipping this step leads to visible imperfections.

    Priming is often the most overlooked step by DIYers. Quality primer seals the surface, provides uniform adhesion, and ensures true color representation. It's especially critical when changing from dark to light colors.
