How To Prepare Walls Before Interior Painting
Proper wall preparation is one of the biggest factors in paint durability and finish quality. Before painting begins, surfaces should be inspected for cracks, nail holes, moisture marks, and prior coating failures.
After repairs, walls should be lightly sanded and cleaned to remove dust, grease, and loose material. Primer should be selected by substrate condition to improve topcoat adhesion and color consistency.
Step 1: Repair Surfaces
Patch small damage and ensure walls are flat before applying any primer or paint layers.
Step 2: Clean Thoroughly
Remove dust and residue to avoid adhesion issues, texture defects, and uneven sheen.
Step 3: Prime Correctly
Use suitable primer for repaired, stained, or porous surfaces to stabilize final coverage.
Step 4: Plan Coats
Most projects need two finish coats for depth, color accuracy, and long-term appearance.

Good prep work reduces callbacks, improves visual consistency, and helps coatings last longer.
