Recommended Spray Apparatus

Several different types of spray apparatus can be used to apply CerMark Laser Marking Materials. The LMM-6000 and LMM-6038
metal marking products are first reduced or thinned with ethanol, acetone or MEK. Thinning ratio is approximately 1 part LMM to 1
part ethanol by volume. This should give you a spray viscosity of approximately 15 - 30 seconds on a #3 Zahn cup. (Slightly thicker
than water like consistency)
The CerMark glass marking materials are ready to spray as supplied. If thinning is necessary, water isrecommended.
Do-it-yourself Aerosol Can
Available at most Ace Hardware stores, Home Depot or auto parts stores, a do-it-yourself aerosol can kit isthe easiest way to get started spraying the CerMark products. This kit, manufactured by Preval, consists of apressurized gas cylinder that attaches to a glass reservoir jar. The marking material is first poured into theglass jar, and then the cylinder is threaded onto the jar. The cylinder pressurizes the jar, and the material canbe sprayed from the nozzle on top, just like an aerosol can.

Hobbyist/Artist’s Airbrush es
A Paasche or Badger hobby airbrush is a very good choice for spraying small samples or tags. These airbrushes will spray a very
precise pattern with minimal overspray, anywhere from a 1 to 4 inch circular pattern from about 4 to 8 inches from the substrate.
Recommended tip diameter is about 1.0 mm or greater.

Recommended Spray Apparatus

The Badger model 250 series brush is an inexpensive single action, external mix, bottom feed air brush. This brush is very good forjobs requiring large overall coverage with medium to heavy viscosity materials and is an excellent brush for spraying the CerMark
products. The tip size on this brush is large, so the CerMark material will spray nicely through it. This brush operates at 20-50 psi linepressure, and the tip adjusts to provide a spray pattern from ¾ inches to 2 inches in diameter.
If your shop does not have compressed air, a small air compressor designed for airbrushes that plugs into 110V household power.
This type of compressor should produce about 0.5 cfm of airflow with a 1/8 horsepower motor in order to provide sufficient air tothe airbrush.

HVLP Spray Gun
To spray a larger samples or areas, a Binks or similar type HVLP spray gun
can be used. A model M1G HVLP gun, similar to what is used in auto
refinishing is recommended. This gun sprays a much larger pattern, abouta 4 to 8 inch pattern from a distance of 8 to 12 inches from the substrate.
It is ideal for spraying tiles and glass with the Cermark LMC marking
materials. It allows for a very even, consistent application over larger
areas. It also can be used with a variety of nozzles and tips; werecommend using a 91P air tip and a 91 fluid nozzle. This gun is used atabout 20- 30 psi line pressure, and uses about 4 - 8 cfm of air, so theappropriate compressed air source must be available.
