The first step in finishing walls and ceilings is deciding what types of materials you will use. This decision influences the order in which you complete the project

Wallboard (pages 132 to 139) is probably the most popular finishing material because it is economical and holds paint and other wallcoverings well. When installed in the proper thickness. wallboard also serves as a firestop or a soundproofing device

When finishing a ceiling, especially in a basement. take into consideration that you may need occasional access to plumbing or electrical wiring in the ceiling. If so. you may want to install a suspended ceiling (pages 140 to 143) with removable ceiling panels If you may need access to mechanicals m a wallboard ceiling, you will have to build access panels (page 129)

In some cases tongue-and-groove boards can be installed directly over framing materials (pages 144 to 147). It can also be installed over wallboard. such as tongue-and-groove wainscoting (pages 162 to 167) which can help disguise uneven surfaces.

Door and window casings (pages 152 to 155). cove moldings, baseboard, and other trim (pages 156 to161) are almost always stained before being installed. Painted trim is usually pr.med prior to installation then painted afterward. Some people prefer to prime and add one coat of paint before installation, adding the final after the holes have been filled with putty.

Lumber for structural applications such as walls, floors and ceilings is usually milled from strong softwoods and is categorized by grade, moisture content, and dimension

Grade: Characteristics such as knots, splits, and gram slope affect the strength of the lumber and determine the grade (chart, opposite page)

Moisture content: Lumber is a-so categ by moisture content S-DRY (surfaced dry) is the designation for lumber with a moisture content of 19 percent or less S-DRY lumber is the least likely to warp or shrink and is a good choice for framing walls. S-GRN (surfaced green) means the lumber contains a moisture content of 19 percent or more

Exterior lumber: Lumber milled from redwood or cedar is naturally res?siant to decay and insect infestation. and is a good choice for exterior applications. The most durable pan of a tree is tho heartwood, so specify heartwood for pieces that will be in contact with the ground

Treated lumber: umber injected with chemicals under pressure is resistant to decay and is generally less expensive than decay-resistant heart-woods. such as redwood and cedar For outdoor structures like decks, use treated lumber for posts and joists, and more attractive redwood or cedar f(x decks and railings

Dimension lumber: Lumber S SO d accord ng to its nominal size, such as 2 x 4. Its actual size (chart, page 17) is smaller Always use actual sizes for measuring and estimating.

The Steel Framing Alternative

Lumber is not the onfy material available for framing walls. Metal studs and tracks offer an attractive—if less common—choice for new con-struction Steei-framed walls can be Installed faster than wood stud walls- the parts are attached by crimping and screwing the flanges— and the channels are precut to accommodate electncal and plumbng lines. Steel Iraming is also tighter in weight, easy to recycle fireproof and comparable in pr>ce to lumber If you are interested in using steel framing for a new wall in a wood-framed home, consult a professional for information about electrical, plumbing, and load-bearing safety precautions Steel framing is available at most home centers

Select suspended ceilings when easy access to plumbing and electrical wiring s critical. If individual suspended ceiling panels become water damaged or broken, they are easy to replace

Finishing Styles

Install tongue-and-groove boards directly over framing, where appropriate and permitted by the building code or install it over waHboard. Holes for light fixtures, switches, outlets, and vents must be measured and cut prior to installation
