MAINTENANCE MANUAL
C. Sags and Runs - Excess paint causes wet paint film to move by gravity and presents a sagging
appearance. Incorrect viscosity, air pressure, and gun handling, or inadequate surface preparation
are frequent causes.
D. Spray Mottle - Sometimes known as orange peel or pebble, is caused by incorrect paint viscosity,
air pressure, spray gun setting, or the distance the gun is held from work.
E. Blushing is one of the most common troubles. It appears as clouding or blooming of paint film. It is
more common with cellulose than synthetic materials. It may be caused by moisture in air supply
line, adverse humidity, drafts, or sudden temperature changes.
9. Storage
A. Store paint, enamel, and other finishing material in dry storage away from direct sunlight and heat.
Mark each container with a code for identification.
B. Storage facilities must comply to Occupational Safety and Health Act (OSHA) requirements
regarding air circulation, lighting, and fire protection. Lock storage facilities to prevent children and
unauthorized personnel entry.
C. Invert pigmented materials every inventory so pigments will not pack to can bottom. Properly
dispose of empty containers.
D. Use older materials first. Useful life of some finishes is limited.
E. Storage area temperatures must be approximately 50-90°F. If finishes are stored in temperature
extremes, allow them to return to room temperature before using.
10. Painting Facility
WARNING: DO NOT BREATHE PAINT FUMES. FUMES DEPLETE THE OXYGEN SUPPLY
REQUIRED BY THE BODY.
A. Painting facilities must conform to local, state, and OSHA standards with respect to air circulation,
exhaust emissions, lighting, and fire protection.
B. Provide sufficient air movement in painting area so there is only a slight finishing material odor.
Exhaust fans must be belt-driven and located near floor level. Locate fan’s motor away from fumes.
C. All spraying area personnel must wear approved respiration safety equipment.
