nation before you begin painting.
SPRAYING VISCOSITY (SPRAY GUN
ONLY) — Paint should be thinned to
spraying viscosity according to the di
rections oh the can. Use only the recom
mended thinner or reducer and the
same amount of reduction regardless of
temperature.
AIR PRESSURE (SPRAY GUN ONLY)
r- This is extremely important. Be sure
you are using the proper recommended
pressure.
TEMPERATURE — the surface to be
painted should be approximately the
same temperature as the surrounding
air. Applying warm paint, to a cold sur-
face, or vice versa, will completely upset
the paint characteristics;
WRONG
Thin coat. Stroke too
fast, not enough overlap,
gun too far away.
THICKNESS — Spray with smooth
strokes. In general, the thicker the coat
of paint, the longer the drying time. Ap-
ply several thin coats about 30 seconds
apart. The paint should remain wet long
enough to flow out and no longer; ;
heavier coats will only produce sags or
wrinkles. Spray a light (fog) coat, fol-
lowed by heavier color coats.
DISTANCE — The Ideal spraying dis-
tance is 8"-12" from the gun or can to
the surface. Shorter distances will pro-:
duce ripples, while greater distances
will result in orange peel, dry film and
poor color match and loss of material
due to overspray.
OVERLAPPING — the gun or can
should be kept at right angles to the
surface at all times. Work; to a wet edge
at an even .speed, using a 50% overlap
and direct the center of the spray at the
lower or nearest edges of the previous
stroke.
RUBBING OUT (BLENDING) FRESH
PAINT — Let the paint dry thoroughly,!
:
Runs or imperfections can be sanded
out, primed and repainted.
Don't be in too big a hurry to remove
the masking. This only produces paint
ridges. When the finish has dried for at
least a week, apply a small amount of
fine grade rubbing compound with a
clean, wet cloth. Use lots of water and
blend the new paint with the surround-
ing area.
CORRECT
Medium coat. Proper
distance, good stroke,
proper overlap.
WRONG
Heavy coat. Stroke too
slow, too much overlap,
gun too close.
