Because flat wall surfaces generally dominate an interior
painting job, some flexibility in applicators is suggested
Natural bristle brushes now have competition from synthetic
brushes made of nylon or polyester which work well for applying
either oil/alkyd or latex paints. Being harder than natural
bristles, they tend to last longer. Since brushes come in
a wide and very specific variety of types suited to different
types of work, it is important to have a painter who will
use the appropriate brush for the paint selected and for
each portion of the job.
One strong advantage of brushing paint on is that the paint
is forced onto the surface and into all of its imperfections.
Thus a good brushedon paint job may last longer if the substrate
is sound and the primer and finish coats are compatible
and of top quality.
There is no harm in using a roller, or even an airless
sprayer, to apply a prime coat to a large flat area. Since
all contemporary commercial paints dry with a smooth surface
anyway, use of a roller or sprayer is acceptable for priming,
and even for a first finish coat.
However, to get paint well pushed into articulated surfaces
and to add some texture to larger flat surfaces, a brush
