How to Paint a Room with an Airless Paint Sprayer

Learn how to easily paint spray interior walls using a Wagner High Efficiency Airless sprayer.



Hi there! My name is Sara Davis, and I blog about my DIY home décor projects at Sincerely, Sara D. Today I’m going to show you how easy it is to paint a large space using Wagner’s Control Pro 130 HEA.

Before you begin, you will want to cover anything you don’t want painted. We moved almost everything out of the room except for the couches and tv stand but made sure to cover them well.
Once everything is out of the space (or covered well), you are ready to go!


Prep walls and floors for spraying

You will need to prep the walls and floors for the paint. I taped off the carpet and covered the base of the room with a roll of brown paper and used painter’s tape and clear plastic to cover the windows (the clear plastic allowed light to come in). If you'll also be painting baseboards on carpet, you can find my helpful trick for painting those on my blog

You will want to primer the interior walls using the Control Pro Airless paint sprayer. I opted not to prime because I had painted the space less than two years ago and I bought a quality paint.

Paint walls

Paint spray the walls of the room with two coats – allowing the first coat to dry before applying the second coat.

The first time I painted the room, I painted in by hand and it took DAYS. This time, it took me under three hours from start to finish.
