(2) Paintbrushes are available in various sizes and shapes. They are used for the following
special purposes:
Large surfaces. Use paintbrushes that measure from 3 to 6 inches wide to apply paint
or stain to large wall surfaces (interior or exterior). Flat wall paintbrushes (Figure 3-
24) are 3/4 to 1 1/2 inches thick and have bristles from 2 to 7 inches long. Large-
surface paintbrushes are usually square-ended and square-edged, with the natural
bend of the bristles bending toward the center.
Sash and trim surfaces. Sash and trim paintbrushes (Figure 3-25) vary in shape and
size, but most are 1 to 3 inches wide. To get close to windowpanes, one paintbrush
has bristles that are beveled like a cold chisel. An angular-cut sash paintbrush is used
by some painters when painting hard-to-reach spots. Another type preferred by some
painters is almost oval in shape.
Clear coatings. Use a paintbrush designed for a varnish (Figure 3-26), shellac, or
lacquer finish. The brush is usually chisel-shaped, which contributes to smoother
applications and prevents lap marks. Paintbrushes are 2 to 4 inches wide and have
extra-fine bristles that are 4 to 6 inches long.
