Spraying Technique - Earlex Pro-8 Operating Instructions Manual

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):
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
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 must move and not the wrist.
The spray gun should always be perpendicular to and approx. 200mm (8inches) 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.
