Stopping Airless Sprayer Overspray | Eliminate Paint Over Spray

What happens here

Proper sprayer setup and technique are crucial for overspray control. Select the correct spray tip, such as a Graco RAC X 515, which is effective for exterior painting. Maintain an appropriate pump pressure, typically between 2200 and 2500 PSI for exteriors, to avoid excessive overspray. Practice 'feathering' by using slight trigger control, rather than exaggerated movements, to start and stop the spray. Keep the spray gun approximately 12 inches from the surface and point it directly at the surface to minimize overspray. A digital readout on your sprayer, like on the Titan 1140, helps precisely monitor and maintain desired PSI.

Goal: Minimize overspray through correct sprayer setup and application technique.

Tools and materials

  • Airless Paint Sprayer Titan — Applying paint to the house exterior
  • Graco RAC X 515 Tip Graco — Controlling the spray pattern and paint flow for exterior applications
  • Pressure Gauge — Monitoring and adjusting the sprayer's PSI for optimal overspray control

What they say

Hide

72-inch film. So, once again, one of the most most important and and key elements in controlling overspray is your pump pressure and your tip. Say you're probably one of the biggest mistakes that painters make is using their tips too long, uh, too much to where they're actually blown out. And um you actually you can actually once you've been spraying long enough with another sprayer, you can tell when a tip is actually new or old by the sound it makes and when it starts to hiss really loud. And if you start to feel droplets coming down on you, you know that that uh that tip is actually worn out. And like I say on ours, a Graco Grao Graco Rackex tip, a 515 tip is what we typically spray our exteriors with. Those tips are typically lasting for about three or four houses. So actually the the tip the gallons calculating it out we're actually using a tip for about 60 gallons of resilience paint. So now some paints are more and less abrasive and they wear the tips out slower or faster. You've just got to go by sound and feel and what that tip is actually doing. So we're using Sher Williams Resilience and those tips are lasting about 60 gallons and then we're buying another tip and we're paying probably about $25 to $30 per tip. And if on a blown out tip, you're going to be on each house wasting about a gallon of paint per house. And that in itself is about $30 right there. So you're going to save the money. It's all going to equal itself out by using a new tip. So don't try to use those tips too long and make sure your pressure is not too high. If you're running your pressure up around 3,000 or higher than that, you're going to get way too much overspray. We run that pressure on exteriors with a 515 tip between 2200 and 2500 PSI. See over here to help control overspray and to actually uh create nice lines on our pipes and and electrical components. You can see how we've masked this situation right here. We got a sprinkler box right here. We got the gas meter right here. We want nice crisp lines on those things. We got another situation right here behind me where we've used our masking to help control overspray. We've got an awning up here, roll out awning. We've just masked that with 9in paper, 1-in tape. We've got a door that we've just wrapped some paper around a glass door to control the overspray. Then we got our window right here that we've masked off, too. And we're just continuing rolling down the line here, spraying. We got a fence here and a heater…
