Correct gun position
To achieve a perfect finish, it is important to move the gun across the surface at an angle of 90° at all times.
- It is important to coat the entire surface evenly. Move your arm at a uniform speed and hold the spray gun at a constant distance from the surface. The optimum distance for spraying is 25 - 30 cm from the spray nozzle to the surface.
- Hold the spray gun parallel to the surface. This means that you must move you entire arm rather than just the wrist.
- Press the trigger on the spray gun after starting to move your arm. Release the trigger again before completing the movement. The spray gun should be moving when you pull the trigger and when you release it.
- Overlap each painting movement by approximately 30%. This helps ensure that the paint material is applied evenly.
- When applying enamels or emulsion paints, spray the peripheral area (edges and corners) first and then cross-coat the large surfaces.
Blocked nozzles can be cleared again very quickly: Just twist the TradeTip 3 or 2SpeedTip nozzle through 180° and pull the trigger. The nozzle is clear again. Caution: When you do this, the spray jet should not be pointing at the object you want to coat.
Spray pressure and viscosity
The spray jet must be uniform. If streaks appear in the spray jet then the spray pressure is too low or the viscosity of the coating material is too high.
Remedy: Increase the pressure or dilute the coating material. Every pump provides a specific delivery rate relative to the nozzle size.
The rule of thumb is as follows:
- Large nozzle = low pressure
- Small nozzle = high pressure
It is important to coat the entire surface evenly. Move your arm at a uniform speed and hold the spray gun at a constant distance from the surface. The optimum distance for spraying is 25 - 30 cm from the spray nozzle to the surface.
