Proper Spray Painting of Outside Corners
e) Welds. Welds are usually rougher than the adjacent
steel and a uniform coating is more difficult to achieve.
Failure often occurs first over welded areas. Thus, after
grinding the welds to smooth them, a coat of paint should be
brushed over the welds. Then the entire surface can be painted
by spray. With this extra coating over the welds, paint often
lasts as long over welds as on the adjacent flat areas.
f) Nuts, Bolts, and Rivets. It is a good coating
practice to brush-coat these areas before spraying the flat
areas. Paint can be worked into crevice and corner areas. Nuts,
rivets, and bolts should be sprayed from at least four different
angles to prevent thin coatings caused by shadowing effects
(Figure 20).
g) Common Errors. Some common errors and the results
that are produced in spray painting are summarized in Table 14.
