How to spray – Technique cont.
The spray gun should be worked as evenly as possible during the spray
operation. Accelerating or slowing down during the spray operation can cause an
uneven spray pattern, spattering or dripping. Keep the sprayer perpendicular to
the surface, otherwise one end of the pattern will be thicker than the other. Keep
the sprayer at right angles to the surface. This means moving your entire arm
back and forth rather than just flexing your wrist.
To achieve optimal spray results, spray back and forth over the surface.
Always hold the spray gun in a horizontal position. If you need to spray upwards
(ie. for ceilings) or downwards (ie. for an unhinged door laid on the table) use the
flexible nozzle extension accessory.
