BEGINNER DIY GUIDE

How to Paint a Room

A clean paint job is mostly won before the roller touches the wall. This guide walks through prep, painting order, supplies, and the small details that keep a weekend project from turning into a touch-up marathon.

What you'll need

  • Interior paint
  • Primer if needed
  • Roller, tray, and angled brush
  • Painter's tape and drop cloth
  • Spackle, putty knife, and sandpaper
  • Clean rags and mild cleaner

Before you start

Check the wall condition, patch damage, and decide whether primer is needed. Dark-to-light color changes, stains, bare drywall, or repaired areas can benefit from primer. Follow the paint manufacturer's instructions for surface prep and dry time.

Step by step

  1. Move furniture away from the walls and protect the floor.
  2. Remove switch plates, outlet covers, nails, and loose hardware.
  3. Patch holes, sand rough spots, and wipe dust from the walls.
  4. Tape only where needed and press edges down firmly.
  5. Cut in around ceilings, corners, trim, windows, and doors.
  6. Roll paint in manageable sections with overlapping passes.
  7. Allow the first coat to dry fully before deciding whether a second coat is needed.
  8. Remove tape carefully, reinstall hardware, and inspect for missed spots.

Common mistakes to avoid

  • Painting over dusty or greasy walls
  • Loading too much paint on the roller
  • Letting a cut-in edge dry completely before rolling beside it
  • Rushing the second coat before the first is dry
  • Skipping enough paint for future touch-ups
