Paint sprayers are advanced tools that have made painting easier, quicker and flawless.From do-it-yourselfers to pros, everybody is using paint sprayers to deal with peeling walls and worn-out cabinets. Although paint sprayers are pretty efficient, there is a problem of overspray that can ruin the finishing look. Overspray doesn’t only affect the look of the final layer but also cause fluid waste and a lot of mess. Fortunately, this problem can be resolved by following a few tips and using the sprayers in an appropriate manner. This review will explain how you can avoid excessive overspray to enjoy smooth finishing and reduced material wastage.
When it comes to spray painting, overspray is a problem that you must address as early as possible. By overspray, we mean the excessive spray that doesn’t land onto the target surface but disperses into the air and creates mess. It results in material waste as well as affects the smoothness of the sprayed area. It’s extremely essential to take effective steps in order to minimize the overspray.
There are many obvious reasons that cause overspray. Wrong tip size, unclean condition of the tool, inappropriate distance between surface and the sprayer and pressure of the gun are some of the few common reasons that trigger overspray. Other than that, the presence and direction of wind and angle of spray gun also increase and reduce the overspray.
Controlling paint overspray is not impossible as there are two effective ways to deal with this problem. First tip is to adjust the pressure control and set it at lower.The higher the pressure, the more the overspray and the lower the pressure, the lesser the overspray. Second tip is to use the correct tip size according to the material viscosity.
One of the major reasons of increased overspray is the high pressure. Sprayers with low pressure strategy cause least overspray because it makes easy to handle and control the material. The problem is when the pressure is high, material bounces on the surface so hard and creates a cloud. The material gets out of control and continues bouncing. The only way to tackle this situation is to reduce the pressure by adjusting it. Prefer spray guns that has pressure adjustment options so you may enjoy reduced overspray and fine application.
Another reason of higher overspray is the wrong spray pattern. Make sure you have set the spray pattern according to the width of the target surface. It the surface is narrow and the pattern is wide then there would be huge mess created by overspray. Use the wide spray pattern only when you are supposed to cover a larger area. When it comes to spraying a smaller portion, set the pattern to narrow so sprayed material won’t miss the substrate. Always prefer the sprayers that comes with a multiple pattern options to allow you adjust accordingly.
It’s obvious that ifthe surface is at left but your spray angle is aiming for right, there would be greater overspray. Experts suggest to keep the angle perpendicular as it allows 99% material to land onto the surface instead of spreading around. It might be a little difficult for beginners to keep the angle maintained but a little practice will make it easier. The angle of 90° is a preferable option whether you are covering narrow or wider surface. It will help reduce overspray to a greater extent.
Another factor that leads tospray paintoverspray issue is the distance between the sprayer and surface. Avoid getting too closer to the surface as it would cause overspray and result in uneven finish. On the other hand, if you will get too far then spray wouldn’t only cover the target area but also the surroundings and create a messy finish. The best option is to follow the instructions mentioned in the sprayer manual. However, distance of 6 to 10 inches is widely considered to be ideal.
The last but one of the most important reasons causing overspray is the direction and pressure of wind. It is strictly recommended to turn off the fan when spraying as it might disturb the paint mist to land onto the surface. If you are working on outdoor projects where wind cannot be avoided, wait for the right time when the wind is slow. The pressure of wind to one direction will cause the overspray by pushing the paint mist into the same direction. It is always best to work in the mild wind.
Paint sprayer least overspray, airless paint sprayer no overspray
Paint sprayers have become the number one choice of amateur do-it-yourselfers and professionals. No doubt, these advanced tools have made painting easier and quicker but there is also some drawbacks of spraying among which comes a biggest problem of overspray. It doesn’t only affect the coatings but also cause material wastage and increased time consumption. Fortunately, overspray can be controlled by following a few tips.You just have to be careful about the tip size and pattern, spray angle and right equipment and then you will be able to reduce the overspray of an airless sprayer as well. Some prepping and safety are also necessary to avoid excessive overspray.
