Spraying water-based paint with an air compressor likewise will considerably reduce the time you invest in painting, leaving you time to do other home chores. A spray gun, a compressor, and an air hose are the fundamental tools you need to execute this task.

Follow these steps to paint with compressed air!

STEP 1: Preparation

As with any paint job, you’re going to have to do a bit of preparation before you begin.

• Select your paint (both oil and latex will work, but oil is much more difficult to clean after the job).

• Before beginning your paint task, you have to get some products in order. First, choose the best type of paint tint and type as well as the paint thinner. A lot of air compressor paint sprayer for walls work best with oil-based paints, but you can use latex and acrylic paints too; just weigh both paints. You’ll likewise wish to choose an excellent paint thinner. Note that mixing your paint with the ideal thinner will allow more paint to spray out of the sprayer and finally help your paint project look much better in the end.

• Prep the room for painting. See our room prep tutorial here.  The key with spraying is making sure EVERYTHING has been taped and plastic covered before painting.  Failure to do so can have a negative effect as you will be spending more time and money cleaning than actually painting.

• Tape off all adjacent surfaces and areas where you don’t want to be painted by your best paint sprayer for walls and ceilings. You ought to likewise cover all furnishings, floor covering, and other home materials with drop cloths to avoid these things from being messed up with paint. Also, ensure that you have a safe, flat surface on which to place your paint to prevent spills and unwanted leakage.

Protect yourself

• Put on a respirator mask, gloves, and safety glasses to protect yourself. Remember that wearing a mask, safety glasses, and gloves will protect you from damaging fumes and particles and other hazardous chemicals incorporated into the paint. This is mainly because you’re doing spray painting house with air compressor, making the paint fine and increasing the hazardous tendency to be contacted.

You’ll next require to sand your paint surface to remove uneven surface areas. You’ll likewise need to use a tack fabric to eliminate any sanding particles and debris from the surface area before you use the best paint sprayer for house exterior. Again, grind, sand, and clean the area of all dust, debris, etc. Rinse the wall when you are done.

• Using a brush or roller, apply a thin layer of primer to the wall.

STEP 2: The Compressor

Now that you’ve prepared the wall to be painted, you may start painting with an air compressor and paint sprayer. You have numerous alternatives in terms of paint sprayers, so make sure you pick the best paint sprayer for house painting. 

One option is a siphon gun with a container hanging under the gun body. Many people think about these types of guns when they visualize spray paint guns. However, siphon guns are not as effective as you might believe. They need greater air pressure and don’t cover a big area when you utilize them. When you pick to use a siphon gun, you’ll need to invest more time and effort to finish your painting project. Nevertheless, if the area you’re painting is small, a siphon weapon may be a good option for you to check.

On the other hand, the gravity gun is similar to the siphon gun since it also stores the paint in a container. The difference is that a gravity gun’s receptacle is connected to the top of the gun body instead of the bottom. Due to the fact that the paint leaks into the body of the weapon through gravity, this weapon requires less air pressure. You’ll find that this tool works better in little areas and is much easier to use after you get utilized to how they work specifically. The only downside is that you’ll require a unique stand to refill the paint container.

Another type of gun is a pressure-feed gun with a pressure pot connecting to the gun through two pipes. The one hose pipe airs to atomize the paint, and the other produces the paint for the gun. Given that this gun has pipes that can vary in length, it is normally the most efficient type of gun.

Now that you know all these things, you have to prepare the compressor to paint! Here’s how:
  • • Turn on the air compressor and let it build pressure.
  • • Using your sprayer’s instruction manual, adjust the regulator to the pressure that is needed. This number is usually between 12-25 PSI.
  • • Attach the compressor to the air hose coupling on the compressor. Make it as tight as possible, and maybe use some Teflon tape to get it even tighter.
  • • Pour some paint thinner into the paint cup.
  • • Identify the metering valve on your paint sprayer, and open it slightly.
  • • Prime the paint sprayer by aiming it at a waste bucket and squeezing the trigger for a few seconds.
  • • Empty the spray cup of any remaining paint thinner.

STEP 3: Painting

Everything is all prepped and ready to go! Next step, painting.

  • • Pour the amount of paint that you think you will need into a separate, clean container.
  • • If its oil, thin the paint with paint thinner. The exact amount depends on your sprayer and paint, but it’s usually around 20% for a good flow of paint.  For latex paint, do the same but with water.
  • • Fill the paint cup on the paint sprayer 2/3 of the way full.
  • • Hold the paint sprayer about 10 inches away from the wall.
  • • Squeeze the trigger to spray the paint. MAKE SURE TO ALWAYS KEEP THE SPRAYER MOVING. This will prevent drippage.
  • • Overlap each pass slightly to avoid leaving spots.
  • • Allow to dry, and recoat as needed.
Change or adjust the PSI to the best air pressure.

Just be reminded to change or adjust the PSI to the best air pressure, then check your paint flow on paper before spraying it on your walls. You can continue adjusting any settings on your gun until you get the proper circulation and pressure for your painting project. The fluid pressure counts on your hand, usually the lowest knob on the weapon, to 0 pressure. Start turning the knob counterclockwise while concurrently pulling the trigger back until it touches the handle. To include adequate pressure to start the paint circulation, slowly start turning the knob clockwise until the trigger slightly takes off the hold and then stop.

Always note as well to practice spraying water on paper before you spray paint. Start the spray weapon in motion before you shoot to avoid thick areas of paint on the wall. Launch the trigger before you stop the movement of the gun. As you spray, ensure you are holding the weapon about 6 to 10 inches from the surface area where you’re painting. Move the spray gun in a smooth, sweeping motion to prevent paint leakage and to drip. Brush out the runs and leakage immediately with a paintbrush, and spray again until you reach your desired outcome.

STEP 4: Clean Up

Now that you’ve painted your room, it’s time for a clean-up!

  • • Dispose of unused paint (tutorial here)
  • • Rinse the siphon tube of your paint sprayer with thinner if oil paint or water if latex paint.
  • • Fill the spray cup with a little bit of thinner (or water if latex paint), and spray until it comes out clean.
