CAUSE

(A) Applying undercoat and/or topcoat excessively wet.

(B) Insufficient dry time between coats.

(C) Improper shop ventilation or heating.

(D) Adding too much or too little hardener to the paint material.

(E) Using the incorrect thinner/reducer for spray conditions.

(F) Omission of drier in enamel/urethane topcoats.



REPAIR

(1) Allow additional dry time, maintaining a shop temperature of 70 degrees fahrenheit or above.

(2) Or, force dry following temperature and time recommendations.

(3) Or, remove soft paint film and refinish.



PREVENTION

(A) Use recommended spray gun, fluid tip and air cap for the material being sprayed. Always adjust the gun for best atomization and balance spray pattern before paint application.

(B) Allow sufficient flash time between coats.

(C) Maintain shop temperature at 70 degrees fahrenheit or above for proper dry/cure.
