Answer

The difference between a professional-looking paint job and an obvious DIY job isn't skill — it's prep and sequence. Most painting mistakes happen before the roller touches the wall.

Prep is 70% of the job

  1. Clear and cover — Move furniture to the center, cover with drop cloths. Cover floors with canvas (not plastic — plastic is slippery and paint can puddle).
  2. Wash the walls — Wipe with a damp sponge or TSP solution. Paint doesn't bond well to dust, grease, or nicotine residue. Bathrooms and kitchens almost always need washing.
  3. Fill holes and cracks — Lightweight spackling for small holes; joint compound for larger repairs. Sand smooth when dry.
  4. Sand glossy surfaces — If painting over semi-gloss or gloss paint, scuff with 120-grit sandpaper. Glossy surfaces don't bond well without sanding.
  5. Tape — Apply painter's tape to trim, window frames, and ceiling edges. Press the tape edge firmly with a putty knife to prevent bleed-through.

Paint in the right order

Ceiling first → walls → trim. Paint moves downward (drips and spatters), so always work top to bottom.

Cut in before rolling

Use a 2–2.5 inch angled brush to "cut in" (paint) a 3–4 inch band along all edges: ceiling line, corners, trim. Then roll the field (open wall area) immediately while the cut-in is still wet. This prevents lap marks between the brushed edges and rolled field.

Rolling technique

Load the roller (but don't overload — a dripping roller creates spatters). Apply in a W or M pattern, then fill in without lifting the roller. Maintain a wet edge — don't let any section dry before connecting to the next section.

How many coats?

Two coats is almost always required for a color change. Three coats if you're going significantly lighter than the existing color, or covering a dark color. Wait the full recoat time (usually 2–4 hours for latex, longer for oil-based) between coats.

The finish matters

  • Flat/matte: hides imperfections, not washable — use on ceilings and low-traffic walls
  • Eggshell: slightly washable, the most common choice for living areas
  • Satin: good for bathrooms, kitchens, kids' rooms — washable
  • Semi-gloss: doors, trim, cabinets — highest durability and sheen
