Airless paint spray tips are sized using a 3 digit number such as 515. The first number has to do with the width of the spraying fan and the last 2 digits refer to the size of the hole or orifice the paint sprays through.

For instance a 508 and a 515 both have the same fan width (approx. 10″) but a different size hole. The 508 has a .008″ hole and the 515 has a .015″ hole. The 508 is used for thinner paints than the 515.

Here is a general guideline for airless paint sprayer tips as far as orifice sizes go as compared to the paint material to be sprayed.

A basic rule of thumb is to use small tip sizes (such as 0.009in, 0.011in, 0.013in) for thin / low viscosity materials such as stains & lacquers, medium tip size (such as 0.015″, 0.017″, 0.019″) for acrylic latex / enamel / emulsion / primer etc., then for heavier viscosity coatings use large orifice sizes (such as 0.021″, 0.023″, 0.025″, 0.027″ etc).

There will be some very heavy material such as putty, drywall mud, plaster, bitumen, fireproofing etc. you will need bigger airless spray gun tip nozzle over 0.031″. Correspondly you need large airless paint sprayer equipment with more than 4L per minute volume.

These recommendations are based on typical 12″ distance from surface being sprayed with an 8-12″ fan size.
