Airless Sprayer is a painting technique which simplifies the process of painting. This technique of painting is often preferred because the result is smooth and has an even finish, which can withstand wear and tear as well as harmful corrosion effects. Airless sprayer is portable and has different sizes and it is available in electric and petrol models. Using airless paint sprayer can simplify your painting in two ways. First, if you want to speed up the job that requires several gallons of paint, the application is faster than using a roller or a brush. And second, if you want your project to be a glass smooth finish on woodwork or doors, the airless sprayer can lay the paint on flawlessly. An airless paint sprayer uses a hydraulic pump system to output high volumes of paint in a fast and efficient manner. In fact, it uses pressure up to 3,000 psi to spray paint out of a tightly secured-hose. This airless paint technique is primarily used for production works because of the ability to cover large areas in a minimal time. It can also reduce overspray so it can save a lot on paint consumption.
There are different brands of the airless paint sprayer but here are the five best quality brands.
Now let’s talk about the benefits that airless paint sprayer can provide. It has a high transfer efficiency which means less waste, and more product application on the surface. It can also provide a fast application in excellent rates and capable in applying thick coatings in high speed. Airless sprayer can apply high-viscosity materials without thinning. It can also provide excellent coverage on irregular surfaces. The important factor of using this is keeping all your costs down. But before we get excited about the benefits of the airless paint sprayer, here are some drawbacks to consider. First, the fine particles of paint don’t all stick to the surface and a large percentage of the paint ends up in the air, where it can drift and settle onto everything in sight. This means you’ll be wasting 20 to 40 percent of the finish, depending on the application. You’ll also have to take extra time to mask it off and cover up everything you want to keep paint-free. Using airless paint sprayer outdoor is also risky. Over spraying can end up on your shrubs or roof, or drift with the wind onto your neighbor’s car. The other downside is the extra time it takes to flush the paint from the pump and hose and clean up the spray gun.
After we learn the benefits and the drawbacks, here are the basic components of the airless sprayer which are made from different individual parts all working together to help make painting much easier.
There are also some other important components of the sprayer, like the Pressure Control, Chassis, the Spray Valve that switch and sets the airless sprayer mode to either Prime Mode or Spray Mode, the Rod which is the piston part of the fluid section, the Intake tube where the material to be sprayed is drawn into, the Return Tube that returns the paint onto the bucket during priming of the pump, the Manifold Filter that is the filter within the sprayer which is the first line of defense against large particles in the paint, and the Gun Filter which is the filter inside the gun and the second line of defense against remaining debris in the paint. And lastly, the Packings, it is the seal in the fluid section which makes the Pump works.
After learning about works of the airless paint sprayer, it is important that we need to know the safety hazards. Now there are two major types of safety hazards in using an airless paint sprayer. The first safety hazard is the fire and explosion. Fire and explosion can occur if the sprayer is spraying or flushing flammable fluid in the area where air circulation is poor and if there’s an open flame or sparks. Many paints, solvents and vapors will ignite causing a fire or explosion which may burn you. With an ungrounded spray system, the flow of the fluid through the sprayer and hose may create enough static electricity to cause a spark from the gun. That spark can ignite flammable vapors. And the second safety hazard is the injection of the spray material. The injection can be caused by high-pressured fluid passing through a small opening, such as the spray tip or hose leak. This creates a high-speed stream of the fluid which is powerful enough to pierce the skin and enter the body. Injection occurs when the high-pressure fluid pierces the skin. The common causes of injection are, placing the hand or the body too close to the spray tip, and grabbing a leaking hose or fitting, even wearing gloves or using a rag. The injury might look like just a cut, but don’t be fooled maybe it’s a serious wound. It is important to prevent this situation by not putting the hand or the body in front of the sprayer tip unless it is off and depressurized. Also it is important to wear safety glasses and work in a well-ventilated area. Like Benjamin Franklin said that “An ounce of prevention is worth a pound of cure.”
The airless paint sprayers are extremely easy to use. Once you learn how to properly set up, clean and maintain each of its parts, you will be able to use it like a pro! There are varieties of techniques that you can use to get the most functionality out of your paint.
