How to Select a Spray Gun Nozzle Tip Size
What Size Spray Tip Should I Use with my Spray Gun?
There are many different things to consider when selecting the
appropriate size spray tip for each job. The amount of information
on the subject can be overwhelming, so we at the Bottom Paint Store
have done our best to make this step easier for you.
There are three main factors to consider when determining the size
tip that will produce the best results.
- First, examine the coating that will be sprayed. Put simply,
heavier coatings will require a larger orifice size than lighter
ones. For example, primers are usually thicker than the
accompanying paint so you should use a 1.7 or 1.8 mm tip to prime
most surfaces. Most painters will stay in the range of 1.2 to 2.0
mm unless the paint being applied is specialized. (See chart
below.)
- The next thing to consider is your project surface area. This
determines the appropriate fan width that your sprayer will
produce, that is, the shape in which the product will leave the gun
nozzle. Airless spray guns have more control over the fan width
than conventional spray guns because the coating is forced through
the tip without being atomized by air. This causes the tip to have
a large impact on the fan width and shape. Most boat projects
consist of large surfaces and so a wide fan will increase the spray
coverage and also provide the ability to spray close to the surface
without too much build up. Smaller surfaces will require a small
fan width to reduce overspray. This also makes it possible to spray
further away from the surface without too much falloff because the
fan is more focused.
- Lastly, consider the spray gun that is being used. Make sure that the spray tip you plan on using
will be supported by the gun. Most spray gun manufacturers will
provide this information in their product overview.
