Prepare Walls, Trim and Ceilings
Interior painting begins with the surface. Nail holes, cracks, loose caulk and damaged drywall should be corrected before the finish coat is expected to hide them.
Furniture and floors also need appropriate protection. The amount of preparation should match the existing condition instead of treating every room as a simple color change.
Walls, Trim and Adjacent Surfaces
Walls, ceilings, doors and trim can use different sheen or coating systems. The project scope should identify which surfaces are included.
A wall color change may require extra coats, while trim can need sanding and adhesion preparation. Repairs should be completed before the final paint sequence begins.
Touch-Up vs Repainting a Full Area
Small touch-ups can work when the existing paint is relatively fresh and the sheen and color match closely. Older paint can fade or change enough that a local patch remains visible.
In those cases, repainting the full wall or logical section may create a more consistent result. The goal is to choose the smallest scope that still produces an acceptable finish.
