2-15. Base Moldings. The interior trim of a building should match or complement the design of the
doors, the windows, and the building. Base molding is the trim between the finished wall and the floor.
It is available in several widths and forms. Two-piece base consists of a baseboard topped with a small
base cap (see Figure 2-34). The common size for this type baseboard is 1 by 4 inches or wider. One-
piece baseboard varies in size from 1/2 by 3 inches to 1 by 4 inches and wider (see Figure 2-35).
Although a wood member is desirable at the junction of the wall and carpeting to serve as a protective
bumper, wood trim is sometimes eliminated entirely.

a. Square-edged (or two-piece) baseboard consists of a square-edged baseboard topped with a
small base cap. When the wall covering is not straight and true, small base molding will conform more
closely to the variations than will a one-piece base alone. This type of baseboard is usually 5/8 by 3 1/4
inches or wider. Install square-edged baseboard with a butt-joint at the inside corners and a mitered
joint at the outside corners (see Figure 2-36, page 2-26).
