How do I know what size spray tip to use?

The tip size is determined by the coating manufacturer. It may be found in the application section listed on the label of the can or bucket of paint. If it is not listed on the can or bucket, you can call the paint manufacturer and ask them for the recommended tip size. There is a general chart guideline on page 12 of the owner’s manual but for the exact size follow the guidelines in the above answer or view our Tip Chart.
