Painting any kind of a building or a room can be quite a difficult task if you decide to use only rollers and brushes. Not only you won’t be able to cover much space with a roller, but these things also tend to leave ugly marks on the walls.

Using a paint sprayer with an air compressor, on the other hand, will allow you to get an even coat of paint on the surface and to cover more space at one time. Have a look at the following tips and learn how to achieve a perfect finish by using a paint sprayer with air compressor:

      • Choose your Paint and Thinner

        Before you start with the project, you will have to get some items in order. The first thing to do here is to get the right type of both paint and thinner. Many models of sprayers work best when used with oil-based paints. However, you can also consider using acrylic and latex paints as well.

        You will also want to choose quality paint thinner. Using the right thinner to mix the paint won’t only cause more paint to get out of the sprayer, but will also help you achieve a much finer finish in the end.

      • Prepare the Area

      • The next step includes preparing the painting area. Make sure to tape off all the adjacent surfaces that you wouldn’t like to get marred with dye.

      • Don’t forget to cover the flooring, furniture, and all other objects and materials that you wouldn’t want to see ruined by paint. You can do all of this by using drop cloths, newspapers, masking or painter’s tape, as well as sheet plastic.

      • Another important thing here is finding a safe, flat surface for the dye cans to prevent spilling.

The next thing you’ll want to do is to remove the rough areas by doing some sanding where needed. Also, use tack cloths to remove sanding debris from all the surfaces you’ll be working on. Next, use soap and water (if you’ll be using latex or acrylic dye) or mineral spirits (for oil-based paints) to wash the surface -rinse it and let it dry completely.If required, prime the surface by applying some thinner with your sprayer. Once you do that, don’t forget to sand and smooth it once again.

          • Wear Proper Outfit

Work safety equipment

When working with painting equipment, it is of paramount importance to protect your skin, eyes, and lungs by wearing proper safety equipment. Make sure to wear a mask or a respirator, gloves, as well as the safety glasses or goggles. Wearing a suitable outfit is bound to protect you from the dangerous particles and fumes that come with painting.

          • Choose the Right Tools

When it comes to the paint sprayers, one has many different options. This is why it’s important to select one that the most suitable for the project you’ll be working on.

One option is a siphon gun. It’s a device with a container which hangs under the gun’s body and is precisely what most people picture when they think of paint sprayers. These don’t cover a large area and require high air pressure, which, unfortunately, makes them somewhat inefficient. In case the area you’ll be painting is a small one, however, choosing a siphon gun isn’t such a bad idea.

The gravity gun, on the other hand, doesn’t have the container attached on the top but on the bottom of the gun body. With the paint flowing into the body of the gun through gravity, this type requires less air pressure. It’s straightforward to use and works great in small spaces, with its only downside being that a special stand is needed for refilling the paint container.

Another type would be the pressure-feed gun, which comes with a pressure pot that is connected to the gun through a couple of hoses. One hose supplies the colorant to the gun and the other air to atomize the dye. With the hoses on this type of a gun varying in length, it is one of the most efficient options when it comes to larger projects.

          • Prepare the Air Compressor

Begin by turning it on and waiting for a while for the pressure to build up. The compressor should have a regular that will allow you to set the pressure for your sprayer. Nobody wants the pressure to go up and down while painting!

Check the manual to find the exact psi setting for your sprayer (it’s probably somewhere between 12 and 25 psi) and set it. Tightly connect the air hose, although the tightness isn’t something you should worry about too much because of the quick connect couples coming on most hoses and sprayers.

        • Prime the Sprayer

Take a paint cup and pour some thinner into it. Plunge the siphon tube in there and slightly open the meter valve. After that, aim the nozzle into a waste bucket and keep pressing the trigger until the thinner stops coming out of the nozzle.

You shouldn’t worry in case you notice only the air coming out -just give the thinner some time. However, if it takes too long, the best course of action would be to take the sprayer apart and check out its components, as something could be blocking the passage.

Remove the leftover thinner and use a funnel to put it back into its container.

          • Pour the Paint

Thin the paint by around 10% to 20% for a good flow and pour it into the paint cup until it fills about 2/3 of it. Lock the container and ensure that it’s properly attached to the sprayer.

          • Start Painting

Pull the trigger and make sure that the distance between the surface and your device is somewhere between 8 and 12 inches. Slightly overlap every pass -this is to avoid leaving thin spots on the surface you’re working on. Moreover, try to use smooth, sweeping motions to prevent any dye from running or dripping.
