For any painting job, it’s important that you use the appropriate tool so you can get the job done in the best and fastest way possible. Painting small and plain or flat surfaces can be efficiently done using a paint brush or a roller. On the other hand, a best paint sprayers may be suitable when dealing with large areas or surfaces with intricate or complex details and imperfections such as cracks, bumps and gaps as paint sprayers are known the smooth and uniform finish that they are able to produce if and when used properly.
Paint sprayers are not usually recommended for small and quick paint jobs because they can require some tedious prep work and cleaning procedures, which can take some time to get finished. Moreover, paint sprayers can be a bit costly as you can lose as much as 75 percent of the paint if the paint sprayer is mishandled or used the wrong way.
There are two types of paint sprayers that you can choose from – the air-powered sprayers and the airless units.
The Air-Powered Sprayer
In terms of price, air-powered paint sprayers generally priced higher than the airless ones and may cost around $200 depending on the size of the compressor. This type of paint sprayer also creates a smoother and more uniform coating or finish than does its airless counterpart as it releases smaller and finer paint particles onto the surface.
This type of sprayer works by using high pressure air to force the paint through the spray gun’s nozzle, which atomizes the paint particles into very fine mists that are sprayed onto the surface and produce a fine and uniform coating.
Spray guns that are used for air-powered paint sprayers come in two types. One is siphon feed air-driven gun and the other is the pressure feed type.
So, how does a siphon-feed spray gun work?
If you are going to paint a large area and want a fine finish for your surface, then a siphon-feed spray gun is most likely what you need. This type of spray gun produces light and fine paint particles that are also ideal for working on areas with complex and intricate surfaces.
This type of spray gun works by using compressed air, which creates a fractional vacuum inside the system as it goes through the intake tube near the nozzle. The air pressure outside goes through a small hole into the paint cup and pushes the paint up to fill in the vacuum. The compressed air then forces the paint out of the nozzle.
When working on a large area or surface using a paint sprayer with this type of spray gun, you will need to stop painting from time to time and refill the paint cup since the nozzle draws paint only from the paint cup.
Another type of spray gun is the pressure-feed gun, which, unlike the siphon-feed spray gun, does not create a vacuum. In this type of spray gun, certain amount of compressed air is directly channeled into the paint reservoir. As the name suggests, pressure-feed spray guns use high air pressure to push the paint up the nozzle propelling the paint out as fine, mist-like paint particles that allow for a fine finish.
The Airless Sprayer
This type of paint sprayer is usually cheaper by considerable amount than the air-powered type of paint sprayer. However, they produce large particles and heavy paint spray patterns, which are not ideal for getting a fine and even finish. Nonetheless, this type of sprayer produces less overspray so less paint is wasted.
Spray guns are classified as bleeder or non-bleeder.
Bleeder guns are used for paint sprayers with compressors that have no air reservoir. With this type of gun, you can turn the paint flow on and off but the air shall continuously pass through the nozzle as long as the compressor is running.
On the other hand, non-bleeder guns have trigger controls that can stop the air from flowing through the nozzle. If the bleeder type of spray gun is designed for use with compressors that have no air reservoir, the non-bleeder type is built for use with compressors that have a storage tank.
Starting a paint job right is just as important as finishing it right. Thus, preparing your work surface, your work area, the paint that you’ll use for your project as well as gearing up yourself would be necessary regardless of the type of paint sprayer that you intend to use for your paint job.
Prep up your work surface
Some of the ways by which you can prep up your work surface is to scrape, sand or clean it with a paper towel or a piece of cloth. Doing so will remove from any dirt and dust that can get trapped in paint once you start spraying.
Prep up your work area
Aside from cleaning your work surface, you’ll also need to prep up your work area by masking or covering areas, which you do not intend to spray paint on. You may also use a large piece of dropcloth, plastic or cardboard to confine, block, and keep oversprays from reaching and hitting untargeted areas.
Prep up your paint
Before feeding paint into your paint sprayer, check your paint for blobs or coagulated large particles of paint, which can clog your paint sprayer’s gun or tip. You may use a commercial strainer or an old stocking made of nylon to filter your paint.
4. Gear up for safety
In any paint job project, your safety should come first as no fine finish can amount to you being safe from any potential harm and accident. Wearing protective and appropriate gears such as a respirator designed for paint spraying, a pair of gloves and goggles, and a long-sleeved shirt would be necessary especially if you would be using a high-pressure best paint sprayer, using a best paint sprayer can be good option for you. Traditionally, to paint house, a paint brush or a roller is used. Which can exert enough force to cause paint to penetrate the skin and put you at risk.
