What is a paint sprayer?
A paint sprayer is equipped with knobs to control the airflow, pressure, and volume of paint, atomizing the material being used and turning it into a fine mist, which makes it easier to apply it evenly to the surface you are working on. When you need to cover a large area, a paint sprayer may be the best choice for you.
Types of Paint Sprayers
For personal use, there are three main types of paint sprayers models to choose from.

Air paint sprayers require a separate air compressor for power and can spray a large amount of paint in a short period of time, but often result in wasted paint. This type of paint sprayer is relatively inexpensive, usually costing around $50.
2. Airless Paint Sprayers
Airless paint sprayers are powered by a power source, either through an electrical outlet or a battery. These paint sprayers work at very high pressures and get the job done faster than the other two types. They work on almost any paint or stain, thick or thin.
Airless paint sprayers help atomize the material without the need for air, spraying more in less time. If not adjusted properly, they can also cause overspray and waste of paint. Airless paint sprayers vary in price depending on size and function, usually ranging from $100 to $400.

HVLP paint sprayers are a popular choice because of their high volume, low-pressure output that reduces material waste. Because of the low-pressure output, HVLP paint sprayers take longer than airless sprayers and require a lot of your patience, but they also deliver high-quality results that meet the needs of DIYers looking for perfection.
HVLP spray guns can be used for projects that include metal, such as painting or varnishing on car fenders, motorcycles, etc. These sprayers have a built-in cup to hold the paint, rather than drawing it from a paint can.
