Remove the door from the hinges, using a screwdriver. Place the door on a clean dry area.
Apply a base coat of paint. Select the color based on the decor of the room. Use a large brush or small roller to completely cover the door with the paint.
Apply the first layer of the faux process. For a marble faux finish, use a rag to roll on a secondary color of paint, leaving gaps and spaces on the door. For a crackle finish, apply a second full coat of a secondary color.
Apply the final layer to the door. For a marble faux finish, use a rag to roll on a third color sparsely. For a crackle finish, apply the crackle glaze and allow it to dry. If choosing a crackle finish, the glaze must be applied prior to the second coat drying.
Paint the edges of the door the base or secondary color.
