The size of the project, environment of the application area, and the pressure setting of your airless sprayer all contribute to the amount of overspray you should expect. Plan on losing 20 – 40% of your material to overspray when working with an airless sprayer.
Do airless sprayers create overspray?
An airless paint sprayer uses pressure to deliver paint through a spray gun and through a tip. By forcing the fluid pass the small opening, the coating is atomized (broken apart). However, because it uses high pressures when spraying, a lot of your paint can become overspray.
Do airless sprayers have less overspray?
Spraying at low pressure helps to minimize overspray while reducing wear and tear on the pump and spray tip. Fairly new to the market are high-efficiency airless (HEA) tips. They can spray coatings at 1000 PSI with the same flow and production levels as standard airless tips—with up to 55% less overspray.
What paint sprayer has the least overspray?
If you don’t mind the noise, need to paint large surfaces quickly, and don’t want to mess with thinning the paint, then an airless sprayer is a good choice. For less overspray and a finer finish on interior projects, HVLP is a better choice.
How far does airless overspray travel?
Overspray from a dry fall coating is dry to a powder within a short distance of the application site; 10-20 feet is typical. Powdered overspray is easily brushed or blown off leaving behind no residue. This unique feature prevents overspray damage without using containment.
How do you paint without overspray?

What are the benefits of an airless paint sprayer?
Speed—airless spraying is faster, thus, more jobs can be completed in less time, using less labor. Airless spraying is up to 10 times faster than brushing or rolling. Quality—airless sprayers produce an even coat of paint on all types of surfaces, leaving a consistent and high quality finish.
Is an airless paint sprayer worth it?
The use of airless paint sprayers is particularly worthwhile in large areas because the advantage of the higher working speed. For a long time, the rule of thumb used to be: use a paint sprayer starting from a 3-room apartment and to paint everything smaller than that roller and brush.
Is HVLP better than airless?
HVLPs are more fine production, not high production.” Unlike airless spray guns, HVLP guns have a second control knob that regulates air flow, giving the user more control over the fan size. There is less overspray, making HVLPs a good choice when working with expensive paint.
Is it better to roll or spray paint?
Paint rolling allows you more leeway when the surface isn’t perfectly clean. Rolled paint goes on thick on the initial coat and bonds better to the surface. The tiny paint droplets produced by spraying do not connect with each other as well as rolled-on paint.
How windy is too windy for airless sprayer?
It is always a good idea to follow label information, but generally, wind speeds of 3 to 7 miles per hour (mph) are preferable. Wind speeds of less than 10 mph are ideal for spraying.
How long does overspray take to settle?
How Long Does Overspray Take To Settle? Do Allow the paint to cure completely After spraying paint, it needs at least 24 hours to cure completely on the other hand.
How long does it take overspray to dry?
Spray paint does dry quickly, but it usually requires at least 24 hours to cure completely. Resist the urge to move your piece or replace any hardware you’ve removed until you’ve reached the curing time indicated on the can. A scratch or fingerprint late in the game will be difficult to fix.
What causes white spots on a painted surface?
Contaminants in the paint can be dirt or other foreign materials, pigment agglomerates or resin gel particles. When hooks and hangers are cleaned in burn-off ovens, the powdery residue, if not completely removed, can fall onto the surface of painted parts.
What is Overspraying?
Overspray refers to that portion of sprayed paint that does not land on the target. It is most commonly encountered in graffiti, auto detailing and when commercial paint jobs drift onto unintended objects. The most common procedure to remove overspray is the use of a special clay bar.
What pressure should I set my airless sprayer?
Full atomization is achieved by adding a small amount of air (5 – 35 psi) to the edges of the spray fan – resulting in a softer pattern, more control, higher transfer efficiency, and less overspray. Selecting the correct spray tip for the job is an important decision.
How do I get a smooth finish with a paint sprayer?
Just wait till the paint is dry and lightly sand it with a fine grit sanding block to smooth it over. Paint over it again and you should be good to go!Feb 5, 2019.
