Helpful Spray Finishing Hints & Problem Solving

Equipment Recommendation
KTM recommends using the DeVilbiss GTI Millennium 2000 HVLP cup or pressure fed spray gun.  With first-hand experience we’ve found that this gun atomizes our coatings with ease and will give you the professional results that you want right out of the box! 


1.Paint Preparation

KTM coatings are filtered before shipping up to 100 microns.  As a standard rule however get in the practice of filtering your paint through a strainer before use.  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.

2. Air-line settings

To ensure that you have enough pressure for continuous spraying make sure you have a tank capacity of 120 lbs. Pressure on the line coming into your booth at all times.  (speak with experts about having the right sized compressor for your shop).  With guaranteed line pressure plumbed into a regulator (see picture) set your pressure to your gravity gun at 45-50 lbs.  This will ensure great atomization of your KTM Coating.  When using pressure fed gun (for best result always use pot with 2-regulators) you may have to increase your pressure to the pot to 65- 75 lbs., put your pressure on the gun to minimum amount (may vary from regulator to regulator) to ensure proper atomization). 

3. 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.  Coupled with air refrigeration excess moisture is removed from the air and accumulated liquid is carried away through either a manual or automatic drain.

4. 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.



5. Spray patterns to avoid

Possible solutions to inconsistent spray patterns:
·  Horn holes plugged - Clean holes with non-metallic point (ie. toothpick)
·  Obstruction on top or bottom of fluid tip - Clean
·  Cap and/or tip seat dirty – clean

7. Keep your gun clean!

Always get in the habit of cleaning your gun thoroughly after each use. Use water to clean all KTM coatings.  Rinse any paint residue completely from gun after use.  At the end of the day remove the air cap from the gun and immerse it in clean solvent. If necessary, use a bristle brush to clean dried paint. Blow it dry with compressed air.
If the small holes become clogged, soak the cap in clean solvent. If reaming the holes is necessary, use a toothpick, a broom straw, pipe cleaner, or some other soft implement.
*Cleaning holes with a wire, a nail or a similar hard object could permanently damage the cap by enlarging the jets, resulting in a defective spray pattern.


What parts of the spray gun require lubrication?
The fluid needle packing A, the air valve packing B and the trigger bearing screw C require daily lubrication with a non-silicone/non-petroleum gun lube.
The Fluid needle spring D should be coated lightly with petroleum jelly or a non-silicone grease (ie. Lithium).
Lubricate each of these points after every cleaning in a gun washer.

Following these suggestions will ensure your success spraying KTM Finishes!
