Interior painting with spray gun

With the right application techniques, it’s tough to beat the flawless finish of sprayed-on paint for uniform coverage of detailed woodwork and cabinetry. The caveat, however, is that preparation, technique and cleanup are extensive, making this painting method unsuitable for most small projects such as a single wall. While consumer-type paint sprayers do a fine job of covering small items like a child’s stool, for professional results on walls and woodwork, an airless spray gun is the best choice. You can rent an airless spray rig from construction rental stores and some paint supply stores.

Set Up the Spray Area

Mask off everything you don’t want painted. This means everything. Fine paint mist can settle on objects on the opposite side of the room.

Cover walls and windows using painter’s tape with an attached plastic drop cloth. Use painter’s tape that’s wide enough to completely cover woodworking if you’re painting walls.

Cover floors with canvas paint tarps, which are also available for rent.


Strain paint from its original bucket into a large, clean plastic bucket through an approved paint strainer to remove globs that can clog the spray gun.

Wear disposable painter’s coveralls with an attached hood, goggles that seal around the eyes and a full respiratory mask, fitted with a chemical filter.

Fill the paint rig reservoir with strained paint and fit the spray gun with the tip appropriate for the type of paint you’re using. The spray gun comes with instructions on the best tip to use for different types of paint. It pays to ask the customer service rep at the rental center what type of rig is best suited to the paint you want to spray.

Test-spray on a large piece of cardboard or scrap plywood and adjust the pressure nozzle until you get an even swath of coverage. Spray guns emit a vertical or a horizontal spray pattern that you can change by turning the tip.

Disposable painter's coveralls protect clothing.

Interior painting with a spray gun?

we have, it is really fast but if your ceiling and walls are different colors it may not be a good idea! we found the best mothod was to spray it then to go over it quickly with a roller bc you have to dilute the paint a bit and it runs. if you go over it with a roller then it evens it out. my BF did the lounge and 2 bedrooms in the time it took me to do 2 walls with a roller :s
we bought ours but bunnings might have one for hire?

How to spray interior paint with a spray gun.

Spray guns apply paint faster than any other method and are commonly used for large paint jobs such as for a room in your home. The advantage of using a spray gun indoors, as opposed to outdoors, is that you do not have to contend with elements such as the wind. Spray guns provide an even coverage of paint to surfaces that contain cracks and crevices. They are capable of applying various types of interior paint such as latex and oil-based paint.
