If front and back are both sprayed, there
may be enough wrap using Technique B or
C to coat a small edge or flange. If wide
flanges are to be coated, this may require
individual coating of edges before the flat
surfaces are sprayed.
NOTE
OVERLAP
For best hiding and uniformity of film thickness, stroke overlap should be approximately 50%. There
should be some overlap at the top and bottom of the part to increase edge coverage. Overlap require-
ments can vary widely with different paint formulations and different compositions of objects being
coated. Individual spray coating operational experience should provide the guidelines for efficiency
in this instance.
TRIGGERING
Applicator triggering (ON/OFF) depends largely on the desired results; the amount of wraparound re-
quired, edge coating, etc. If front and back of the object are being coated, proper applicator technique
can effect edge coating (in some instances) without making a specific pass for this purpose. Examples
of different trigger times and the results that can be expected are illustrated.
A. Little or no wrap - incomplete coverage
B. Fair - some wrap
C. Good wrap (Triggered 2" to 3" past edge)
D. Too much overstroke may produce heavy
edges and produce more overspray.
