Painting Applications

Home / Tech Tips / Painting Applications
Why is air control equipment necessary?
Raw air, piped directly from an air source to a spray gun is of little use in spray finishing. Raw air contains small, but harmful quantities of water, oil, dirt and other contaminants that will alter the quality of the sprayed finish. Air filters filter out these contaminants before they get on your paint job. Air entering the filter is swirled to remove moisture that collects in the baffled quiet zone. Accumulated liquid is carried away through either a manual or automatic drain.  
What causes excessive pressure drop on the main line gauge of the filter/regulator?
  • The compressor is too small to deliver the required air volume and pressure for all tools in use.
  • The compressor is not functioning properly.
  • There is leakage in the air line or fittings.
  • Valves are partially opened.
  • The air line, or piping system, is too small for he volume of air required.
How do I prepare the paint?

Always prepare paint in a clean, dust-free environment. Paint has a remarkable ability to pick up dirt. Dirty paint will not only clog your spray gun, but it will also ruin your paint job. Get in the habit of always pouring paint into the cup or tank through a paint strainer

What are the advantages of using electrostatic equipment over conventional spray equipment?

There are many advantages to using electrostatic spray equipment. The primary advantage is an increase in transfer efficiency. (45% – 90%) With the increase in transfer efficiency, clean-up costs go down, material usage drops and disposal cost decrease. Electrostatic methods also lower solvent emissions into the air since less coating material is needed to coat each part.

I have flow, but how do I know if my fluid regulator is working?

If a fluid regulator fails it can no longer hold back fluid pressure. If the outlet pressure climbs up to equalize with the inlet pressure when you stop dispensing, the regulator has lost the ability to shutoff or fully regulate flow. If you have pressure limits set you will get a High Outlet Pressure alarm. If you have job volume limits set you will get a High Volume On Last Job alarm.

My user’s manual says that I don’t have to clean the unit when you take breaks while painting. I want to know if it is okay to leave the sprayer loaded overnight? If I plan on spraying with the same paint the next day do I have to clean the unit, store it and then load it up again the next day?

It is recommended that you flush the unit out every night to prevent paint from curing in the pump, which can be time consuming and costly to correct. Flush per the instruction and store the sprayer with mineral spirits in the hose and gun and mineral spirits or pump armor in the pump.

I maintain my sprayers with my own mixture of spirits, solvents and mild cleaning solutions. Is there any material I should avoid using for this process?

Our pumps are designed to withstand almost all solvents and cleaning solutions. In general, it is recommended that you complete your cleaning by flushing mineral spirits through the pump section, but other petroleum-based products and cleaning solutions will suffice if necessary. Also it is discouraged to blend solvent can be hazardous.

How often should I tighten the packing nut on my airless sprayer?

It’s a good practice to check the packing nut on a weekly basis and slightly tighten if it is necessary. Paint visible in the wet cup or on the rod surface is an indication that paint is starting to pass by the throat packing and the packing nut needs to be tightened. Depending on the style, put a flat-blade screwdriver or punch on the head of the packing nut and tap it lightly with a hammer. Tighten just enough to stop the paint leakage, DO NOT over-tighten. New or repacked pumps generally need retightening after the first several gallons. If the nut has been tightened completely and paint continues to leak past the seals, repack the pump.

Do I have to flush my sprayer at the end of the day?

It is recommended that you flush the unit out every night to prevent paint from curing in the pump, which can be time consuming and costly to correct. Flush per the instructions and store the sprayer with mineral spirits in the hose and gun and mineral spirits or Pump Armor in the pump.
