Interior Walls

Drywall sheets are applied to studs, joists or rafters with special drywall nails, drywall screws or special adhesive. Joints between panels are taped with a paper or fiberglass tape and coated, along with nail heads, by several layers of smooth, plaster-like wallboard compound ("mud"). Most outer corners are reinforced with metal or square-edged or rounded corner bead.The sheets, which are relatively inexpensive, are 4 feet wide, 1/4 to 5/8-inch thick, and from 6 to 16 feet long. The standard size is 1/2-inch thick and 8 feet long.

Plaster is a mixture of portland cement, sand and water that is applied in a thick, mud-like consistency to a base of wood or metal lath or perforated plasterboard. It's applied in layers. First, a scratch coat is troweled onto the lath so that it oozes through and grips the backing when it hardens. Then a finish or white coat is troweled on the scratch coat for the final, smooth surface.

Wood paneling has been used as a wall covering since walls have been walls, though it's now used primarily as an accent for a study or family room where its warmth and character are wanted. Wood paneling is made both in sheets and in individual, interlocking strips. It's glued or invisibly nailed to existing walls or furring strips; furring is always needed when paneling is applied to masonry walls.
