There are hardly any airless sprayer models that weigh more than one hp. Airless paint sprayers are versatile tools that you may use to accomplish indoor as well as outdoor projects. From painting wooden doors to retouching metal cladding roofs, you can use an airless sprayer for a variety of projects. When it comes to recoating projects, there is no best option than using an airless sprayer.
Most people prefer HVLP sprayers, but they are not suitable for large-scale projects. Airless paint sprayers are quite efficient in covering larger surfaces quickly and smoothly.
The high pressure fast flowing fluid lands on the surface in a whip and coats it smoothly. It will save your time, material and efforts. The flawless finish an airless paint sprayer offers cannot be achieved with the use of any other paint application tool.
In less time with fewer efforts, you can enjoy a glass-smooth layer of coating. When using an airless sprayer, you are not bound to work with specific materials. From electrostatic to water-based to latex paints, you can use the airless sprayer to apply any fluid. Airless sprayers apply wet coatings that adhere quite firmly to surface and form an active, even layer of paint.
Such a good adhesion results in the long-lasting coating. An airless paint sprayer consists of different components. Each one of them has its efficiently roll in improving the working of the tool. All parts work together to achieve the goal of paint application. Here we will discuss the components of an airless sprayer and their functions.
Comparing to the traditional airless, the fluid in an air-assisted airless is passed to the gun at more comfortable low pressure, somewhere between psi. As the fluid passes through the tip, it is partially atomized into small droplets.
Experience atomization takes place when a small amount of air ranging from psi is added to the edges of the spray fan. It results in a smoother application, reduced overspray and high transfer efficiency. The spray tip and air cap of an air-assisted airless sprayer control the amount of fluid sprayed and add air into the spray fan. The gun works as the on-off valve that manages the flow of the liquid. The air adjustment valve enables air to reach tip as close as possible for a softer application.
The hose is used to transfer the fluid from the container to the gun while motor system enables the pump to perform. There is also a digital display that allows users to regulate the fluid pressure according to project requirement. Air-assisted airless also has an air compressor that delivers air to the gun.
An airless spray tip plays an integral part in paint application. It is responsible for determining the fluid flow and also used to adjust the spray pattern to apply fluid in a right direction. A shabby spray gun tip has a bigger orifice and decreased fan width.
These factors affect the spray pattern significantly. Continuing working with a poor spray gun tip results in higher overspray, material loss, and low-quality paint application. This situation will lead to increased material loss and overspray. You will repeatedly overlap for consistent thickness, but it will only ruin the look and make it appear uneven.
This chart above illustrates the effects of a worn-out tip on spray pattern. There is a variety of airless spray gun tips in the market graded according to the size of the orifice.
When it comes to choosing the best one, consider the type of project you want to accomplish. Some project requires little application while some involve too much of it. You have to make sure that the tip you choose is compatible with your project requirements. Also, check if your preferred spray gun tip is suitable for your airless unit or not. Spray tip selection can also be made from coatings. Small tips are ideal for light surfaces such as enamel and stain while large tips are perfect for thicker coats that involve the application of latex paints.
Consider your project type and coating goals; you can choose a fine spray gun tip for your airless unit. One thing you need to understand is that spray gun tip never lasts longer and you cannot use a worn out tip to achieve desired results. Almost all airless sprayer models have a pump that is used to regulate fluid flow.
The fundamental function of a shoe is to deliver an even flow of liquid through the hose under high pressure. It is powered by three sources, electric motor, compressed air, and gas engine. The electrical and gas powered pumps come with a motor that generates a continuous rotation with crankshafts and connecting rods. There are also hydraulic powered pumps that operate when hydraulics are used to transfer the power. While compressed air motors work with the flow of air causing piston and rod to move upward and downward.
When choosing an airless sprayer, you will come to know about four different types of motors: Universal, AC, Dc and Brushless Dc. Here we have provided a quick comparison of all four models regarding advantages and disadvantages. Considering recent changes, DC motors have improved significantly.
The main workings of an airless paint sprayer. Rather than the force of the piston driving gears as it would in a car, airless paint sprayers use a series of one-way valves which force pressure into the machine and hold it there, with each cycle adding more fluid and pressure into the closed system.
When you pull the trigger on the spray gun, this high pressure is forced through a small spray tip and atomizes the paint into tiny particles the spray. Once the pressure starts the drop, the sensors detect the change and fire up the electric motor which drives the piston and works tirelessly to maintain the required amount of pressure for you to continuously spray.
This airless technology is what is used in smaller DIY airless sprayers, as well as large commercial airless texture sprayers such as the Graco Mark V or others from the Graco paint sprayer range , simply with bigger motors, pistons, and cylinders. A professional sprayer system often consists of a base unit, a hose, a spray gun and a spray nozzle or spray tip , and perhaps a frame with wheels for added portability.
These models are very popular as they can be moved around easily, and are preferred by contractors as they are perfect for use in large spaces. Most semi-professional airless sprayers such as the Graco Magnum X7 , and all professional airless spray systems are designed so that the paint is delivered directly from the container and these are among the most versatile of all.
Well, aside from the recommended annual litreage that most manufacturers provide for each model, there are typically 3 main categories of airless sprayers:. If you need to tackle more comprehensive work and require a commercial sprayer , then, of course, you need to consider the bigger, more powerful models that can deal with thicker materials. Electric sprayers range from huge commercial machines to small DIY machines.
The right airless sprayer for you boils down to three key performance indicators , they are:. As with all power tools and machines, there can be problems to look out for that come as part and parcel of the design. This is not to say the machines are faulty or of poor design, but with paint — as with brushes and rollers — comes with its own set of problems. If you need a sprayer that you will use on a regular basis you will need one that can be professionally serviced.
Some are more capable in this area than others, so it is worth checking customer reviews for more information. Many models come with a built-in flush system, which allows you to simply flush the left over fluid out of the hose and nozzle in a few minutes.
This means you can change colors or types quickly and gives you a great deal of added versatility. These are very handy for using on smaller, regular jobs around the home, and are both popular and affordable but may be a bit gimmicky and not be the best for professional contractors.
Finally, these airless paint sprayers can produce a higher pressure, which is great for speeding up the painting process. This can also have its drawbacks, both with the risk of overspray and as a potential safety concern, but with pressure control, you can maintain safe usage even with thicker paints. An airless paint sprayer provides a higher pressure than traditional HVLP spray guns exactly because it doesn't use an air compressor. While a typical spray gun builds up a pressurized block of air that is forced through the spray tip, the airless sprayer does not do that.
A pneumatic spray gun uses the stream of air to create an area of low pressure that draws the paint into the flow, creating a mixture of atomized paint and flowing air, which drives the paint to the surface. This, unfortunately, introduces air into the process very early, severely increasing the risk for bubbles and defects appearing, which can be detrimental to the quality of your project. If you examine examples of painting jobs performed by airless paint sprayers and High Volume, Low-Pressure Sprayers, you'll see a marked difference between the quality of the finish.
An airless spray gun uses a motor to power a diaphragm pump or something similar to build up pressure within the paint itself. Because the paint itself is holding the pressure, it becomes more pressurized than the lower pressure air flows from a pneumatic spray gun.
This has been criticized as potentially dangerous, but adjustable pressure control and safety technology have made these power tools just as safe as the alternative, meaning you can easily use them without any additional risk of injury, and you can also provide a better-finished product than with a pneumatic tool.
When you are airless paint spraying you will use the tool exactly like a pneumatic version. Using the attached suction tube, you can use a bucket of paint and begin to draw paint through your setup. The paint will come out in a fan pattern depending on which different tip you decided to use for your sprayer. You can adjust the hose length and the pressure of the device. Make sure to go in overlapping swathes to ensure you get complete coverage and to make sure the project looks even all around.
You will have some overspray, which is unavoidable since the paint is literally floating in the air. Once your surface is painted, just make sure to properly clean your tool when it's out of use. That way, next time you plan to use it, you won't have any issues. There are a couple of different types of airless sprayers on the market, and all of them have their own various benefits. A handheld spray gun is a very small version of the larger power tool which is perfect for DIYers. These handheld spray guns hold a very small amount of paint or lacquer and sometimes even use a battery to power the small motor.
These are much more portable and easy to use, but they cannot handle large projects since they simply do not have the capacity. Cart Airless Spray Guns are airless paint sprayers with the motor and tank mounted on wheels.
This way you can roll it around to all the different areas of your project. These combine the capacity of large paint sprayers with the portability of a handheld gun, so you can reach distant parts of your project. A standing airless spray gun is mounted on a stand. These are typically the largest and most powerful. They also usually have very long hoses so you can stretch them farther without having to move the airless sprayer anywhere. These devices are powerful tools, not toys.
As such, they need some education on how to properly use. If you're interested in purchasing one, there are some great tools available online to teach you how to load, spray, and clean these devices.
