Paint and Paint Manufacturers
PROBLEM
SOLUTION
Do not know what type of paint to
use
When ordering paint from manufacturer:
D
Inform paint suppliers of type of equipment to be used (RoadLazer),
filter screen sizes (30 mesh) and tip sizes (33 to 45 thousands).
D
Require that paint must pass through a 30-mesh filter with minimal
filter plugging.
Things to know about waterborne paint and striping equipment:
D
Flush waterborne paints from system if system is not used on a regular
basis. Waterborne paints do not dilute easily. Use warm soapy water to
flush system.
D
Waterborne paints will not redissolve. Dried paint film in paint
containers or paint suction lines must be removed. Graco offers a
Suction Line Strainer Kit 240499 that should be installed at least 2 ft
from pump inlet to remove contamination. Strainers must be cleaned
regularly to avoid pump starving or cavitation.
D
Waterborne paints cannot freeze or tolerate temperatures above
120
_
F (49

C). Consult paint manufacturer.
D
Use only Graco 300 grade stainless steel wetted replacement parts.
Other metallurgic choices will have serious compatibility and corrosion
problems, such as system plugging. Most plastics and epoxy coatings
used for paint transfer and paint storage are chemical compatible.
Consult paint manufacturer.
D
With age, waterborne paint pigments settle to bottom of container.
Never use settled paint without agitating. It is important to order fresh
paint. Require paint manufacturers to supply manufactured dates and
stagger shipments throughout striping season.
