How to Prepare a Room for Painting

  1. 1
    Schedule a full day for preparation.
  2. 2
    Choose a color.
  3. 3
    Prep the floor and hardware for painting.
    • Remove any switch plates and electrical outlet covers, putting painter's tape over them.

    • Canvas sheet down on the floor, covering it completely. Secure the canvas with painters tape and make sure it doesn't move around.

  4. 4
    Sand the wall(s). Sanding is helpful because it creates small pores or pockets into which the paint can get, making for a more even layer of paint.
  5. 5
    Clean the wall(s). With a vacuum, clear the wall off all the dust and debris dislodged by the sanding process.
  6. 6
    Patch up any holes or breaks with compound or caulk.
  7. 8
    Cover the wall with a coat of primer. A primer is a lighter coat of paint that absorbs colors well.
    • Wet the roller before dipping it into the paint .Wet with water for latex-based paints .Wet with paint thinner for oil-based paints.
    • Fill the tray with enough paint to nearly get up to the grate.
    • Dip the roller into the back reservoir and bring it back up against the grate, squeezing out the excess paint while evenly coating the roller.
    • Roll the paint onto the wall using a "W" or "M" shape. After dipping the paint into the tray, use continuous "W" or "M" motions to coat the wall with paint.
    • While doing the "W" or "M" motions, don't move the roller off the wall. Keep the roller on the wall until it needs another application of paint. When the roller starts to make a peeling, sticky sound on the wall, it's time for another application of paint.
    • Allow paint to dry several hours. Touch up with a second coat of paint, if necessary. Repeat the original process used to apply the paint for best results.
    • If applying paint to broader areas of trim, use a wide, straight-edged brush. If applying paint to thinner areas of trim, use an angled brush.
