Many different patterns and styles are made from a variety of both softwoods and hardwoods. These profiles can be used individually, and some are combined to create intricate patterns.
Molding in older homes may be made of plaster (particularly cornice and crown molding) or any of several hardwoods or softwoods. (Before you strip the paint from any older surfaces, find out whether the old paint contains lead-sanding or stripping such paint creates a toxic hazard.)
New molding profiles are sold at lumberyards and millwork shops, the best places to see the wide selection available. Hardwood molding meant to be stained or finished naturally is relatively expensive; much less expensive are paint-grade pine or fir molding made from short pieces of wood that are “finger joined” together. You can also buy a range of ready-to-paint, highly decorative molding profiles made from high-density polymers.
Most molding materials are nailed in place with finishing nails; nailheads are set beneath the wood’s surface and filled with spackling compound or, for a molding meant to be stained rather than painted, pigmented wood filler.
Basic profiles of molding run the gamut from simple rectangles to intricate patterns. Many of these styles are combined with one another to form base molding, ceiling molding, casing, chair rails, and other styles.
Ceiling molding adds a decorative element at the tops of walls and provide a gentle transition from wall to ceiling. Depending upon a room’s style, these may be a simple cove pattern or a highly intricate crown molding.
Door and window casing covers the gap between wall and door or window jambs. Styles range from simple to intricate, built-up varieties.
Base and base-with-shoe styles hide the joint between wall and floor and protect the bottom of the wall from shoes, vacuum cleaners, and the like.
