How to Use An Airless Paint Sprayer: Comprehensive Guide
1. Setting Up an Airless Sprayer
Go with the best advice.- Having an accurate pressure gauge on your sprayer is essential, but having the appropriate tip might be just as crucial. There is a trade-off between pressure and coverage, however, and larger tips often need more pressure to cover the same amount of land. Contrarily, precise tasks need pointy tools with narrower points. To find out what kind of tip will work best for your project, describe it to a hardware expert.
Thin the paint.- Although latex paint may be used in airless sprayers, it has to be diluted before use. Mix in a quarter cup of water or chemical thinner for every gallon of paint you’re using. You may need to test out various paint concentrations. Put some into the spray can and see how well it covers. If the spray is uneven, try diluting it with thinner.
- Airless sprayers are designed to work best with latex paint.
- Chemical thinners may be purchased at most hardware and paint retailers. These are superior to using water, and they don’t interfere with the paint’s natural qualities.
- Consider the surface you’ll be painting on before making your final selection.
Filter the paint before using it. – No matter how well you stir the paint, some solid paint particles may remain. Airless sprayer nozzles are easily clogged. If you want to get rid of the solid particles in your paint, you may use a strainer to transfer it to a different bucket.
Connect the siphon hose.– To spray paint, an airless sprayer uses a hose to transport the liquid. Carefully insert the rear of the device into the paint bucket, and then attach the siphon hose to it. Doing this before priming is recommended. When the paint begins to flow freely from the nozzle, you will know that the priming process is complete.
Prime the pump. – Priming is a necessary step before using any airless sprayer. This is a rather simple task since most airless sprayers feature a “Prime” option that facilitates this. An airless sprayer that isn’t priming properly may benefit from a gentle tap with a hammer. Any dried paint within the sprayer may be loosened in this way.
– While priming the sprayer, keep the nozzle facing down in a bucket to catch any stray paint.
Give your sprayer a quick check before each use.-Check the sprayer’s pressure and level before each use. Large spills may be avoided if you check the condition of your sprayer beforehand. Look for tiny cracks in the hose. Make sure the filter is clean and the nozzle is working properly. Make sure the paint is being applied evenly by giving it a brief test run on a surface.
2. Methods of Spray Painting Without Compressed Air
Prepare the surface for painting. – Preparation of the area around the surface to be painted using an airless sprayer is necessary, as is the case with any other kind of paint application. Parts of the surface that shouldn’t be painted may be masked off using tape. Spread the tarp on the floor to catch any spills.
There are many benefits to using an airless sprayer, but one negative is the potential for paint to go everywhere. When painting outside, the wind might take up your paint and transfer it to other surrounding walls and surfaces. Tarps should be kept over other areas to prevent this from occurring.
To spray, squeeze the spray bottle’s trigger.– It’s the same as using any other gun while working with an airless sprayer. If you’ve never used a painted prayer before, it’s a good idea to get some practice on some scrap paper. A water spray may serve as a practice tool.
The pressure may be adjusted as necessary. The need to raise the pressure is indicated if the paint is not spraying thickly and uniformly. You can adjust this using a dial on your airless sprayer. In general, however, you want to use the least amount of pressure that won’t compromise the quality of the paint job. Using excessive pressure shortens the lifespan of the sprayer.
Keep your distance constant as you spray. — Spray the paint onto the surface from a distance of 10-12 inches (30.5 cm). Because of this, it will be near enough for an efficient application, yet far enough away to cover a wide area.
Keep your aim moving.- Maintain a steady forward momentum with your goal. Too much pressure on the trigger might cause overspray and leaking. Maintain constant hand movement over the painting surface to prevent this problem. You should try to maintain a fairly constant pace. To get the best results from your paint job, ensure sure it is uniformly applied. If the paint doesn’t seem to be spreading evenly, proceed more slowly.
Release the trigger to stop painting. – The paintbrush may be put down after a set number of strokes if the trigger is released. You need to think about the split second between when you let off the trigger and when the paint stops flowing.
3. Caring For Your Airless Sprayer
After each usage, rinse off the spray bottle.— If a sprayer of paint is left for too long without being used, the paint inside will dry and become difficult to remove. After each usage, the sprayer should be thoroughly rinsed and dried. Pull the nozzle out of the sprayer and wipe away the paint with a moist paper towel. Make sure the spray paint doesn’t get ruined by moisture by drying off the nozzle after use.
- For safety’s sake, don’t let the sprayer sit unused for more than 20 minutes. The paint will set if you do that.
Check hoses for breaks before use. – Before using an airless sprayer, make sure the hoses are in good working order by inspecting them for any signs of wear and tear. If there’s a micro-fracture anywhere in the hose, it will spray out the paint and lessen the effective pressure of the device. You may accomplish this by visually inspecting the hose for cracks and by touching it out for any rough spots.
Filters should be changed as needed. – A filter is the face covering the intake of your sprayer. You should change your filter if it has been perforated or if it is more than 20% blocked. Many airless sprayers come with a couple of replacement filters, but you can buy them pretty cheaply wherever you purchase the sprayer.
Never put your safety at risk. – High pressures generated by airless paint sprayers make it easy to injure oneself if the paint is sprayed straight onto the skin. Paint may be injected into tissues or the circulation without causing any outward signs of injury. The skin may dilate to let the paint in, then close up again to conceal the wound. If you’ve ever had what’s called a “fluid injection injury,” you know how serious it is and how quickly you need medical attention.

FAQs How to use an airless paint sprayer
Q. How do you use an airless paint sprayer?
Hold the airless paint sprayer gun (guard and spray tip removed) over the waste bucket and pull the trigger. Switch the valve to the “spray” setting. Let go of the trigger when the paint is flowing in a steady stream from the gun. Lock the trigger and follow the “Pressure Relief Steps
Q. What is the number one rule when using airless spray guns?
A good rule of thumb for an airless spray gun is to hold the gun about 12- 14 inches from the surface of the product.
Q. Do you thin paint for airless sprayers?
Most beginner or hobby paint sprayers require the paint to be thinned because they don’t have enough power to suck up and push out anything thicker than stain. But, thinning the paint a little bit is even a good idea with a professional-grade paint sprayer too – it creates a prettier, less bumpy finish!
Q. Is it hard to paint with an airless paint sprayer?
Airless spraying is the fastest way to complete most painting jobs. Learning how to use an airless sprayer is quite easy, but like anything new, practice and a little knowledge will help you achieve professional-quality results in no time.
Q. Do airless sprayers use more paint?
With an airless paint sprayer, you will use 40% more paint than if you brushed or rolled. That means 40% of the paint that you’re spraying ends up somewhere else besides your paint surface. Poor spray painting techniques can increase this ratio to 50/50.
Tips: The going rate for airless sprayers is about USD 200. Instead of buying a sprayer only for one task, it could be more cost-effective to rent one instead.
Always remember to keep your paint sprayer in a dry, low-pressure area.
Warnings: Although airless paint sprayers are highly recommended due to their quickness, they do have one big drawback: the paint does not stick to surfaces as effectively as it does when using other methods. You may assume that you will squander at least 20% of your paint during application.
