The tip you choose depends on the size of the job, the thickness of the coating you need and the material you are spraying. The two variables on spray tips are the size of the orifice and the width of the fan. A larger orifice delivers more paint per square foot, while a wider fan width delivers less. Choose the tip to regulate paint flow to minimize dripping, sagging and over spray while maximizing coverage. Keep in mind the type of paint you are spraying, remembering that the gun sprays stains and thin paints like primer faster than it sprays heavier exterior paints and enamels. If paint is sputtering from the gun, consider using a tip with a wider orifice before thinning the paint.
