In this video, This Old House general contractor Tom Silva discusses some of the many options available for trimming out the interior of a room.
How to Choose Molding:
- Clear hardwood moldings are expensive and used when you wish to apply a stain and varnish or just varnish.
- Clear pine molding has no knots and is suitable for staining and varnishing, or just varnishing.
- Clear, primed moldings are finger-jointed together from shorter pieces of wood, and are intended to be painted.
- Moldings made from MDF (medium-density fiberboard) are economical and come primed and ready for paint.
- Polymer molding has an attractive wood-grain finish, but can be stained or painted.
- Crown molding comes in a variety of sizes and styles and is installed at the top of the wall up against the ceiling.
- Baseboard moldings, which run along the bottom of walls, can be made from a flat board topped with a narrow base cap, or bought as a single piece with the top edge routed with a decorative profile.
- Baseboard is available primed for painting, or clear for staining and varnishing, or just varnishing.
- Shoe molding or quarter-round molding is used at the seam between the baseboard and the flooring.
- Chair rail goes flat against wall at about 30 to 36 inches high.
- Beadboard is used to create wainscoting along the lower portion of walls.
- Beadboard is typically topped with rabbetted piece of decorative trim.
- Colonial trim is often used for casings around windows and doors; installation typically requires mitered corners.
- To avoid cutting miters, square-cut the casings and install rosette blocks at the corners.
