Repainting the interior of your home is one of the most inexpensive ways to update the decor or ready your home for sale. While painting new gypsum board surfaces can be challenging, repainting interior rooms is a straightforward process that can be completed by almost any homeowner.
Step 1: Measure the size of each room and calculate the square footage you must cover with paint. To make the calculations, multiple the height and width of each wall and subtract the area of doors and windows. Once you have the square footage for each room, determine how many coats of paint you will require. Two coats is the minimum; drastically changing colors will require a tinted primer as well as at least three coats of paint. Armed with these numbers you should be able to purchase the correct amount of paint for each room.
Step 2: Begin by covering the floor with drop cloths to protect against paint spills. Try to move any furniture to the center of the room or to another room before attempting to repaint the interior. Cover anything that cannot be removed from the room with a drop cloth.
Step 3: Before repainting the interior of any room fill in any holes with joint compound using a utility knife. Allow the repairs to dry thoroughly and lightly sand to remove any grooves before continuing with painting.
Step 4: Use painter’s tape to cover any woodwork or molding that should not be painted. Newspaper and painter’s tape can be used to protect larger obstacles, such as window sills, from drips. Remove any face plates covering electrical sockets and light switches with a screwdriver.
Step 5: Empty all of the buckets of paint you intend to use to paint a single room into one large bucket and mix the paint thoroughly. This will protect against color variations that can occur between different cans of paint. Pour some paint into a paint tray and keep the rest of the paint covered to prevent evaporation.
NOTE: To facilitate color changes, consider using a tinted primer as your first coat of paint. Primers will help you achieve the color you want in fewer coats by preventing the old paint from bleeding through. If you do use a primer before repainting the interior walls, just apply it like you would the first coat of paint.
Step 6: Use a brush to apply paint around interior doors, windows, and other obstacles. Also repaint corners and other areas that may be difficult to reach with a paint roller.
Step 7: Use a paint roller to apply paint over the remaining interior wall surface. Work in a zig-zag fashion, covering the wall in several different directions for best results. Remove the painter’s tape and allow the area to dry completely.
