CAUSE
|
REMEDY |
| A |
Material not thinned out sufficiently. |
Add the correct amount of solvent by measure. |
|
B |
Failure to deposit a wet coat. |
Check solvent. Use correct spread and overlap of
stroke. |
| C |
Spray gun stroke too rapid. |
Take deliberate, slow stroke. |
|
D |
Insufficient air pressure. |
Increase atomizing pressure or reduce fluid
pressure. |
| E |
Using wrong air cap. |
Select correct air cap for the material and feed. |
|
F |
Spray gun too far from the surface. |
Stroke the spray gun 6 to 10 inches from surface. |
| G |
Spray gun too close to surface. |
Spray gun should be worked 6 to 10 inches from
surface. |
|
H |
Overspray striking a previously sprayed surface. |
Spray detail parts first and end with wet coat.
Hold spray gun so over spray hits unsprayed work. |
| I |
Poor thinner, too hot. |
Use better grade of thinner for material or add
retarder to allow flow-out. |
|
J |
Material not thoroughly dissolved. |
Mix material thoroughly. |
| K |
Drafts. |
Eliminate excessive drafts. |
|
L |
Humidity too low. |
Raise humidity of room. |
