Brush vs Roller vs Sprayer for Interior Painting

Each tool wins in a specific situation. Mixing them well is how a paint job goes from okay to professional.

Brushes cut in edges — ceilings, trim, corners. Buy one quality 2.5" angled sash brush (Purdy XL Glide or Wooster Silver Tip) and care for it. Cheap brushes leave bristle marks and shed into the finish.

Rollers handle the bulk of the wall area. A 9" frame with a 3/8" nap microfiber cover is the right default for most interior walls. Use 1/2" nap for texture, 1/4" for smooth doors and trim. Always back-roll after the first pass to even out the film.

Sprayers are unbeatable for cabinets, doors, trim runs, and full empty rooms. Output is even and smooth, and what would take a day with a brush takes 30 minutes. The trade-off is masking — for one or two walls in a furnished room, masking takes longer than rolling would.

My typical interior repaint: brush to cut in ceilings, corners, and around trim; 3/8" roller for walls; sprayer for any doors or cabinets I removed and laid flat in the garage. That combination is faster and looks better than picking just one tool.
