SPRAY TIP SELECTION
Two tips having the same tip size, but different pattern widths will deliver the same amount of paint
over a different area (wider or narrower strip). A spray tip with a narrow pattern width makes it easy to
spray in tight places .
Thickness of the paint coat per stroke is determined by spray tip "fan width", rate of the spray gun
movement, and distance to surface.
PATTERN WIDTH
SPRAY TIP SELECTION
Spray tip size is based on how many gallons of paint per minute can be sprayed through the tip. Do not
use a tip larger than the maximum pump flow rate or capacity the sprayer can accommodate. Pump flow
rate is measured in gallons per minute (GPM).
Spray tip selection is based on paint viscosity, paint type, and job needs. For light viscosities (thin paints),
use a smaller tip; for heavier viscosities (thicker paints), use a larger tip size.
During use, especially with latex paint, high pressure will cause the orifice to grow larger. This destroys
the pattern.
Replace tips before they become excessively worn. Worn tips waste paint, cause overspray, make
cutting-in difficult, and decreases sprayer performance.
