Tape off anything adjoining the wall that you don't wish to paint, such as woodwork. Place drop cloths on the floors and furniture.
Paint the base coat color around the top of the wall as well as against taped-off surfaces with a latex paint, using a three-inch nylon-poly paintbrush. Paint far enough from the ceiling and taped-off surfaces so that a paint roller won't inadvertently touch a surface you don't want to paint. This is called "cutting in."
Pour base coat color into a paint pan, filling it halfway. Paint the remainder of the wall with the base coat, using a 3/8-inch paint roller. Allow the base coat to dry completely, usually 12 to 24 hours.
Load a clean brush with crackle glaze. Brush entire surface in one direction, and only apply one smooth and even coat. Do not vary the brush strokes as crackling glaze must be applied in one direction. The wall will appear shiny and wet. Generally, the thicker the crackle glaze is applied, the larger the cracks will be. Allow one hour to dry.
Apply the second color of paint, the top coat, in the opposite direction in which you applied the glaze. Cover the base coat color and crackle glaze completely.
