If you’re considering updating the paint on your home, it’s challenging to know what type of paint to buy. It would help if you had something that would smoothly, evenly, and leave a good finish. There are three basic types of painting: airless, air-assisted airless, and electrostatic spray painting.
Airless, Air-Assisted Airless Spray Paint
Paint has traditionally been applied with a spray gun. Airless spray paint guns produce only a fine mist of paint that settles quickly, requiring two or three coats to achieve color and sheen. Airless spray paint is available in an infinite range of colors, finishes, and tints; it cleans up easily with water; and one can apply it in temperatures as low as -4ºF (-20ºC) or as high as 150ºF (66ºC).
Spray painting is an economical way to paint various surfaces, including metal, wood, brick, and concrete. In most cases, two coats will meet the needs of any porous surface. It’s possible to apply paint onto brick or concrete with a pressure sprayer. However, most applications require a semi-auto or brush-type sprayer.
Air-assisted airless spray paint is also suitable for painting a wide range of surfaces, although coverage may be slower. Air-assisted airless paint is heavier than standard spray paint, so it covers better in fewer coats. It dries to a heavier film than traditional spray paint, making it ideal for sheathing wooden siding. Because the fine mist settles immediately, two coats are usually sufficient.
Using a sprayer to paint a brick or concrete wall
Airless or air-assisted airless spray paint provides a good finish and is an economical choice for many applications. The main drawback of airless spray paint is that it’s pretty messy to apply. Depending on the painting task, you may need multiple coats of paint to achieve your desired color.
Airless spray paint has a wide range of applications and can be applied to wood decks, siding, metal, concrete, and other surfaces. Like other types of paint, airless spray paint comes in an infinite array of colors and finishes. It’s available in cool silver or black finishes. Airless spray paint is user-friendly:
· It cleans up easily with water.
· Removable tips are available for cleanup.
It’s possible to use a pressure sprayer to paint a brick or concrete wall as long as the temperature is above freezing. At lower temperatures, you should use a brush-type or semi-auto sprayer.
Air-assisted airless paint is heavier than traditional styles of paint, so it covers better in fewer strokes. It dries to a more complex film than standard spray paint, making it ideal for painting wooden siding.
Air-assisted paint is also suitable for wood fences because it dries to a hard film resisting peeling.
The advantage of an airless sprayer over a brush is that the material flows through the device in a continuous, steady stream. Airless sprayers are ideal for large surfaces or areas where accuracy is critical.
Alternatively, you can use an air-assisted airless sprayer to apply paint to wood siding, so you don’t have to use a brush. An airless sprayer lets you apply paint in cooler temperatures and eliminates the need for a brush — however, coverage may be slower.
Airless spray paint is messy to apply. Depending on the painting task, you may have to apply multiple coats to achieve your desired color. You typically need two or more coats to achieve a uniform finish on porous surfaces such as brick, concrete, and wood. It may be challenging to achieve the required coverage for larger surfaces.
Heavier than air-assisted airless spray painting
In most cases, airless spray paint is heavier than air-assisted airless spray paint. It’s necessary to use a brush or a semi-auto sprayer when you’re applying paint to wood or concrete with an airless system. However, with an air-assisted system, you’ll have fewer strokes and spread more paint per stroke. Like most types of paint, it’s easier to apply when applied in cooler temperatures and requires fewer coats.
Typically, airless spray paint costs more than traditional spray systems. If you’re painting a large area, you’ll need to spend more time applying coats with a brush-type or semi-auto sprayer. It’s possible to apply multiple coats of paint with an airless sprayer.
Airless spray paints can’t be applied to vinyl siding. You’ll need an airless system or a specialty brush to apply paint.
It would be best to consider the cost of the paint and other supplies, including primer and any necessary cleanup materials. You’ll need to purchase more paint than you would with a traditional spray system.
With an airless sprayer, you typically don’t have much control over the paint flow rate. If you’re painting in cold or cool temperatures, you’ll need more paint than using a standard spray system. With higher temperatures, the paint will dry faster and may appear too light compared with other paint types.
You can’t easily apply paint to the siding.
Electrostatic Paint Sprayer
It is an airless spray paint system ideal for tile, cellulose, wood, and plastic. It’s user-friendly because it allows you to paint in temperatures as low as -4ºF (-20ºC) or as high as 150ºF (66ºC). You can also apply any paint to most surfaces, including metal, concrete, and even porcelain. The airless sprayer will produce anything from a fine mist to a thick liquid film.
It’s a versatile machine because you can apply it in temperatures below freezing. It’s excellent for applying paint to wood siding, decking, and fencing. You can also use it to spray paints that include solvents, toluene, or acrylics. The Electrostatic Paint Sprayer uses a piston pump to deliver a constant paint supply from the can nozzle to the tip. It sprays in large, consistent “drops” from the tip without spitting. It is also quieter than most airless sprayers.
It’s easy to clean up after you’re done spraying.
You don’t need to worry about the paint drooping onto other surfaces as it dries. You can use a basin as a catch basin as well as a paint roller for cleanup. The electrostatic system also gives you the added benefit of an airless system since there is no air compressor or other moving parts — it simply requires electricity. It makes cleanup very simple.
It’s a good choice for applying paint to a variety of surfaces.
The Electrostatic Paint Sprayer works well on porous surfaces, such as plastic and wood, and non-porous surfaces, such as metal. It will not rust or corrode any metal surface from which it sprays. Two people can operate this system at the same time. This is an ideal option for spraying paint on large walls or surfaces.
It’s easy to use
All you need to do is read the included instructions, and you’ll be spraying paint with confidence. The Electrostatic Paint Sprayer was designed for easy use. It works great on most surfaces, including wood, brick, and concrete.
It’s bulky and heavy even at its lightest setting; however, it can carry up to 120 lbs (54 kg) of paint without slowing down. It’s impossible to adjust the flow rate and paint output. The Electrostatic Paint Sprayer can spray a wide range of thicknesses, making it ideal for spraying materials such as oil-based enamel or even paint-containing solvents.
The system is prone to clogging and requires regular cleaning, but it’s easy to clean up after you’re done spraying. It can handle all types of paints because it sprays a very consistent film. You can use it to apply paint inside or outdoors.
The Electrostatic Paint Sprayer works well on most surfaces, including concrete, brick, wood, and metal. It’s ideal for large-scale jobs. Because of its oil-based paint capability, it can even handle some solvent-based paints. Due to the extra equipment required to clean the system after you’re done spraying, this may not be an ideal choice for small jobs.
You can’t use it to spray water-based paints. It is ideal for spraying paints that contain solvents, such as lacquer, enamel, or shellac. You can also use it to spray paint that contains oil-based stains, urethane, or epoxy sealers.
Weighing the pros and cons of airless spray painters is the key to determining the best choice for your painting project. If you are coating hard surfaces rather than applying paint to wood, look for an airless sprayer designed for systems such as acrylics and lacquers. While airless spray coating is not the fastest or the easiest option, you can save time and money with this spray system. However, you’ll need to purchase an airless system if you plan to paint in cold temperatures or if you want to apply paint in industrial or industrial-scale jobs.
