Step-by-Step Instructions

Phase 1: Room Assessment and Deep Cleaning. Remove all furniture from the room or consolidate it in the absolute center. Cover the furniture and floors entirely with your canvas drop cloths. Unscrew all switch plates and outlet covers, storing the screws safely in plastic bags. Finally, wash the walls from top to bottom using your diluted TSP solution and a sponge. Removing hidden grease ensures your new paint adheres flawlessly.

Phase 2: Patching and Sanding. Inspect the drywall for nail holes, dents, or accidental gouges. Fill these imperfections with spackle using your flexible putty knife. Allow the spackle to dry completely, then sand the patches flush with the wall using your 120-grit sanding block. Run your bare hand over the repaired areas; if you feel a ridge, you need to sand it again.

Phase 3: Taping and Priming. Apply painter’s tape meticulously along the baseboards, window casings, and door frames. Press the tape edges down firmly with your putty knife to prevent paint from bleeding underneath. Next, roll a single, even coat of primer over the entire wall surface. Primer creates an ideal canvas, neutralizing the old wall color so your chosen palette shines true.

Phase 4: Cutting In. Dip your 2.5-inch angled brush into the paint, loading only the bottom third of the synthetic bristles. Hold the brush like a pencil and carefully paint a two-inch border around all taped edges, room corners, and the ceiling line. Work in small, manageable sections so the cut-in paint remains slightly wet when you begin rolling.

Phase 5: Rolling the Walls. Load your 3/8-inch nap roller completely, ensuring it drips slightly back into the pan. Start at one corner and roll the paint onto the wall using a wide “W” pattern. Fill in the gaps by rolling straight up and down, slightly overlapping your wet edges to prevent visible track marks. Allow the first coat to dry according to the manufacturer’s exact instructions before applying a mandatory second coat.

Critical Safety Warning: Always keep a window open or use an exhaust fan to maintain proper ventilation. If your home was built before 1978, you must consult the Environmental Protection Agency (EPA) lead safety guidelines before sanding any existing surfaces. Disturbing lead paint releases highly toxic dust. If a test returns positive, immediately halt work and hire a certified lead abatement professional. Additionally, hire a pro if your project involves vaulted ceilings over 12 feet, as working on tall scaffolding poses severe fall risks.
