HomeRight Paint Sprayer 101

Using a paint sprayer can be a little intimidating, especially if you haven’t used one before. Whether you’ve used paint sprayers before or they are a new concept to you, using a paint sprayer can make your painting projects much easier, regardless of the painting project size. 

This general overview will help familiarize you with what paint sprayers are and how to choose the right sprayer for your project, large or small. 

1. What is a paint sprayer? 

Paint sprayers use a piston system that’s built right into the sprayer head. The pump uses hydraulic technology to shoot the paint through small openings in the gun's head, which can be done at pressures of up to 1,000 Pounds per Square Inch (PSI). Airless paint sprayers work with a variety of both paint or stain materials, including: oils, latex, acrylic and water-based.

2. Selecting the correct paint sprayer for your project? 

  • Watts - The higher the wattage, the thicker the paint/stain moves through the sprayer unit. 
  • Flow (Gallons per Hour) - A paint sprayer is usually rated by the amount gallons the sprayer puts through the unit per hour. The higher the number, the larger the flow rate which is very critical when covering a large surface area. 
  • Square Feet per Hour - You’ll need to determine how large your current project is (square footage) and how quickly you want to cover the space. The larger the area, the larger the unit you’ll want to purchase, because you’ll finish the job quicker. 
  • Material - Determine the type of paint or stain material you’ll be using. Depending on the thickness, you’ll need to find a sprayer powerful enough to spray the material effectively. The more powerful the unit, the less you’ll have to thin the paint or stain.
