Step 1 - Find you paint or stain thickness to work out your tip size

You've got yourself an airless spray painter and you want to work out the right size tip.

Firstly we need to work out your paint or stain thickness which will determine the tip size you need to use.

Pro Tip:

  • User smaller tip sizes when applying thinner materials such as stains and enamels.
  • Use larger sizes for thicker materials such as exterior, latex and oil based paints.


Step 2 - Match the tip size to the fan width to work out correct tip size

Secondly, you’ll want to work out the fan width that’s required to work out your spray tip.

Pro Tip

  • Number calculation, it’s the first digit is half the fan width (5 x 2 = 10 inch fan width)
  • It’s the last two digits that are the size of the tip opening in thousandths of an inch.



Step 3 - Confirm your selected tip is supported by your sprayer equipment

Finally, you’ll want to confirm it the selected spray tip size is supported by your sprayer equipment.



Step 4 - Let's look at an example

A 515 tip compared with a 523 tip. Both tips will spray a pattern 10 inches wide but the 523 tip will produce a thicker coating provided you use the same sprayer pressure and hand speed.

On the other hand, keeping the orifice size the same and increasing the fan width allows you to spread the same amount of material over a wider area.

When it comes to choosing tips, you should start by checking the coating manufacturer’s instructions; they have researched optimum tip sizes for the viscosity of their particular products.

Having said that, the range of tip sizes available allows you almost infinite control of your spraying finish and quality.
