If your wallpaper is in good condition, paint over it than remove it, as removing it can cause damage to the walls, especially if it has been on the walls for a long time. If the wallpaper you are painting over is exceptionally textured, apply a thin coat of joint compound to smooth out the surface and prevent any traces of the texture from showing through the paint.

When you are ready to paint, begin by using a brush to apply paint to the edges of the wallpapered surface, moving from corner to corner. Using a roller, paint from the ceiling down to the floor. For every 3-foot by 3-foot section, form a "W" shape and color it in fully by moving the roller back and forth over the area. You should apply two full coats of paint, allowing the first coat to fully dry before applying the second.
