When paint is sprayed through my airless sprayer the paint runs or sags down the wall. What is causing this?
The paint is going on too thick. This can be caused by a number of things. • The operator is not moving the gun fast enough. Increase the speed that the gun is being moved over the painting surface. • Select a spray tip with a smaller orifice size. For example: if you are using a 419 tip, try using a 417 or a 415 tip instead. This will reduce the amount of paint leaving the gun. • Select a spray tip with a wider fan pattern. For example: if using a 317 tip, try using a 417 or a 517 tip instead. • The gun may be to close to the surface being painted. Hold the gun further back when spraying.
