How Do You Paint A Room With A Sprayer?

Painting a room by yourself can be a pretty daunting task that can be especially time-consuming if you’re using classic methods such as using a roller.

But nowadays, paint jobs such as painting a room can be accomplished much quicker using paint sprayers. What used to be a task that could take a couple of days or even weeks sometimes can now be done in just a couple of hours using sprayers.

That being said, a lot of first-time users and those who are unfamiliar with too have asked the question, “how do you paint a room with a paint sprayer?”, and while it might seem complicated at first glance, it’s actually really simple.

How Do You Paint A Room With A Sprayer?

To paint a room using a sprayer, one will first have to set up the paint sprayer, which can be a different process depending on the model being used.

Once everything is set up, the next step is to start spraying. Make sure to keep the tip of the spray gun 20cm to 30cm away from the surface that’s being painted and keep the paint gun moving, making even and consistent strips of paint until the room is completely painted.

While it may be a fairly simple process, it can be pretty confusing, especially if it’s your first time. So to make things easier for you, we’ve made a quick and convenient guide to using a sprayer to paint your room.

Read on to learn more.



How To Paint A Room With A Sprayer

Step 1: Prep The Room

To start the process, you first have to prepare the room for painting. This means clearing out all the furniture, and if you can’t remove all of it, remove as much as you can and then move the rest to the middle of the room, leaving a lot of space for painting and for your equipment.

From there, you will have to put masking tape and paper over the surface you don’t want covered in paint. This usually means covering the windows, doors, and trim. It’s also recommended to turn off the electricity in the room then removing the cover plates on all outlets, switches, and electrical fixtures. If there are switches that remain, simply cover them with tape and protective paper.

Additionally, it will be beneficial to fill in all the nail and screw holes with a spackling compound using a putty knife.

Step 2: Prep The Sprayer

Once the room is ready for painting, the next step is to prep the sprayer.

The process will differ depending on the sprayer you have, so make sure to check out the user manual beforehand. For most handheld and HPLV sprayers, you will have to load the appropriate reservoir with thinned paint, attach your chosen spray tip (make sure the hole size doesn’t exceed the maximum capacity of your sprayer), then turn it on.

However, for airless sprayers, you will first need to prime them. While this might take some effort and time, these sprayers are more heavy-duty and can handle thicker, un-thinned paints, which can be very convenient for some people. To prime the sprayer, simply put the priming tube into a waste bucket, place the suction tube into your paint bucket, switch the valve to the “prime” setting, then turn the sprayer on until paint flows out of the priming tube.

From there, all you have to do is load the hose and gun with paint then you’ll be ready to go.

Step 3: Find The Right Pressure & Spray Pattern

Once everything is set up, you will have to find the right pressure and spray pattern before you actually start painting.

It’s best to do this on a scrap piece of cardboard as opposed to testing it on a wall. Simply turn the sprayer on and paint a strip onto the cardboard. If you notice any dripping, that means your pressure is too low and you simply have to turn it up. Once the paint stops dripping, that means you have the right pressure and you’re ready to start painting the room.

Step 4: Start Spraying

This next step might seem intimidating at first, but it’s actually very easy once you get the hang of it.

When painting any surface using a sprayer, it’s recommended to keep the tip at least 20cm-30cm away from the surface to maximize the capabilities of your sprayer. To paint a surface, simply pass the sprayer over the wall, making sure to keep the sprayer moving and keeping the nozzle perpendicular to the surface.

When doing the next pass, you will want to overlap around 30%-50% of the previous pass, which essentially gives you two even coats. Start by doing this horizontally and once you’ve painted the entire surface, do another coat, but this time working vertically.

Step 5: Cleanup

Once you’ve finished painting the entire room, you’re ready for the last step, which is cleaning up.

Afterall, no DIY project is truly finished until everything has been cleaned up. Start by removing the tape and protective paper from the surface you didn’t want painted, which should be done after the paint has dried up, exposing neat and clean lines. From there, simply move the furniture back into the room and put back all the electrical fixtures that have been removed.

It’s also important to clean your sprayer after every use by following the directions in your user manual. Different models will have different methods of cleaning, so make sure to check to read the manual so you don’t risk damaging your equipment.


And there you have it. A quick and easy guide to painting a room with a paint sprayer.

These tools can make paint jobs much easier and quicker to accomplish, which is why they are a favorite tool of DIY-ers everywhere. When painting a room with a sprayer, always remember to keep the spray tip 20cm-30cm away from the surface that you’re painting and to keep it moving at all times.

And if you keep that in mind and make sure to follow the directions and steps properly, you’ll have a fully-painted room in no time!
