Select the term(s) that describe what you are experiencing.  






COLOR ISSUES: The coating appears to be the wrong color in the pail.

POSSIBLE CAUSES: Pigment settles over time and gives the appearance of being the wrong color.

SOLUTION: Stir/mix the coating properly. Refer to the product's technical data sheet for mixing instructions.


DRY SPRAY: A dry spray finish is characterized as a rough (almost sandpaper like), non-smooth, texture. 

POSSIBLE CAUSES: Dry spray commonly occurs, as a result of, fluid pressure too low or atomizing air pressure too high on a sprayer, the spray gun too far from the part, dry overspray from adjacent surfaces or the spray gun speed is too fast.

  • Fluid Pressure Too Low

    • A fluid delivery that is too low for the atomization air supplied will be over-atomized. This is common for heavier materials used in suction and gravity feed guns. The coating may need to be thinned. Consult the technical data sheet. 

  • Atomizing Air Pressure Too High

    • Air pressure that is too high for the volume of the coating being supplied will create paint droplets so small that much of the solvent easily evaporates. The coating does not flow with the lower solvent content. In addition, the increased air pressure causes additional bounce back with adds to the problem. Use the minimum air pressure required to achieve the atomization required.

  •  Dry Overspray from Adjacent Surfaces

    • Use a technique that does not allow overspray from the part being sprayed (or adjacent parts) to land on what has already been finished. 

  • Gun Speed Too Fast

    • Operating a gun at a high speed typically results in a film build that is too thick which doesn't allow the coating to flow. Typical hand speed for air atomized guns is about 3 feet per second. 

  • Gun Too Far from the Part

    • If the spray gun is held too far from the part, the solvent has increased the time to evaporate. Use these recommended distances

      • HVLP             6-8 inches

      • Air Spray        8-10 inches

      • A/A Airless     10-12 inches

      • Airless           12-14 inches 

SOLUTION: Refer to items listed above. Allow the coating to dry, sand smooth and re-coat. 


DRYING/CURING ISSUES The coating is drying slower than expected/required.

POSSIBLE CAUSES: Humidity, Temperature, Improper Ventilation and Unclean Surfaces can contribute to slow dry times. Other potential causes are (1) Using the wrong amount of "B" component (too much or too little), (2) Insufficient flash-off time between coats, or (3) Incorrect spray technique (coating applied too heavy). 

SOLUTION: Refer to the product's technical data sheet to determine: the appropriate application conditions, surface preparation instructions, the proper coating mix ratio, film thickness recommendation and the appropriate flash-off time between coats. 


SHEEN ISSUES: The appearance fo the finish looks foggy, patchy or dull. 

POSSIBLE CAUSES: Using too little coating is often the cause of sheen issues since it prohibits or impedes the correct flow and level of the coating. 

SOLUTION: Refer to the product's technical data sheet to determine the proper application wet mil-thickness. 


SOLVENTS TO REDUCE & CLEAN UP COATING: What solvent(s) should be used to reduce a coating &/or clean up after painting? 

SOLUTION: Refer to the product's technical data sheet to determine the appropriate solvent to reduce/thin the coating and clean application equipment.
