SPRAYING TECHNIQUE
The most commonly used technique for painting a wall is the ‘cross-hatch’ technique, i.e. you apply
the product in horizontal lines and then cross over these lines by applying the product in vertical lines
(Fig.3):
Let go of the trigger at the end
of each spray movement to
avoid excessive paint and drips
Fig. 3
1. Adjust the Air Cap to obtain a Vertical spray, then pull the
Trigger and move your arm across to the right.
2. When you get to the end of the line, release the Trigger
for a moment and then apply the material in the opposite
direction just beneath the line you have sprayed.
3. Proceed in this manner applying the material in Horizontal
lines overlapping your previous coat by 1⁄3 to 1/2.
4. Next, adjust the Air Cap to obtain a Horizontal spray and
apply the product in vertical lines over the lines you have just
sprayed.
Release the trigger to avoid overspraying which will cause the material to run. Cross over the horizontal
lines (sprayed with a Vertical pattern) with vertical lines (sprayed with a Horizontal pattern). Only the
forearm should move and not the wrist.
The spray gun should always be perpendicular to and approx. 1-8 inches (25-200 mm) from the spray
surface. Spray parallel to the surface using controlled smooth passes at an even speed.

SELECTING NEEDLES, FLUID TIPS AND AIR CAPS
When pairing the Pro-8™ Spray Gun needles and aircaps together it is important to look at the markings
on both the needle and the aircap. The aircap has the actual size laser marked onto the front of the
aircap itself. The needle has a size laser marked onto the shaft.
Below, we have put together a chart showing what the various Aircap sizes we offer for the Pro-8 Spray
Gun and the corresponding needle identification numbers which they are paired with.
