Spraying

POSSIBLE INjEcTION HaZarD. Do not spray without the tip guard in place. Never trigger the gun unless the tip is in either the spray or the unclog position. always engage the gun trigger lock before removing, replacing, or cleaning tip.

Spraying Technique

The following techniques, if followed, will assure professional painting results.

Hold the gun perpendicular to the surface and always at equal distance from the surface. Depending on the type of material, surface, or desired spray pattern, the gun should be held at a distance of 12 to 14 inches (30 to 35 cm).

Move the gun either across or up and down the surface at a steady rate. Moving the gun at a consistent speed conserves material and provides even coverage. The correct spraying speed allows a full, wet coat of paint to be applied without runs or sags.

Holding the gun closer to the surface deposits more paint on the surface and produces a narrower spray pattern. Holding the gun farther from the surface produces a thinner coat and wider spray pattern. If runs, sags, or excessive paint occur, change to a spray tip with a smaller orifice. If there is an insufficient amount of paint on the surface or you desire to spray faster, a larger orifice tip should be selected.

Maintain uniform spray stroke action. Spray alternately from left to right and right to left. Begin movement of the gun before the trigger is pulled.

Avoid arcing or holding the gun at an angle. This will result in an uneven finish.

Offspray

Proper lapping (overlap of spray pattern) is essential to an even finish.

Lap each stroke. If you are spraying horizontally, aim at the bottom edge of the preceding stroke, so as to lap the previous pattern by

50%.

For corners and edges, split the center of the spray pattern on the corner or edge and spray vertically so that both adjoining sections receive approximately even amounts of paint.

When spraying with a shield, hold it firmly against the surface. Angle the spray gun slightly away from the shield and toward the surface. This will prevent paint from being forced underneath.

Shrubs next to houses should be tied back and covered with a canvas cloth. The cloth should be removed as soon as possible. Titan gun extensions are extremely helpful in these situations.

Nearby objects such as automobiles, outdoor furniture, etc. should be moved or covered whenever in the vicinity of a spray job. Be careful of any other surrounding objects that could be damaged by overspray.

Practice

1. Be sure that the paint hose is free of kinks and clear of objects with sharp cutting edges.

2. Set the pressure to minimum by turning the pressure control knob to the “MIN” setting.

3. Move the PRIME/SPRAY valve up to its SPRAY position.

4. Turn the pressure control knob clockwise to its highest setting. The paint hose should stiffen as paint begins to flow through it.

5. Unlock the gun trigger lock.

6. Trigger the spray gun to bleed air out of the hose.

7. When paint reaches the spray tip, spray a test area to check the spray pattern.

8. Use the lowest pressure setting necessary to get a good spray pattern. If the pressure is set too high, the spray pattern will be too light. If the pressure is set too low, tailing will appear or the paint will spatter out in gobs rather than in a fine spray.
