Hey guys! Having trouble with your airless spray gun? Don't worry, you're not alone! Airless spray guns are fantastic tools for achieving a smooth, professional finish, but like any piece of equipment, they can sometimes run into snags. Whether you're dealing with sputtering, clogging, or pressure problems, this guide will walk you through common issues and how to fix them, so you can get back to your project in no time!

Airless Spray Gun Not Spraying

Airless spray guns not spraying can be super frustrating, but let's troubleshoot this step by step. When your airless sprayer refuses to spray, the first thing you should check is the power supply. Ensure that your sprayer is properly connected to a functioning power source. Sometimes the simplest solutions are the most overlooked! Next, inspect the spray gun's trigger mechanism. Make sure it's moving freely and not stuck or jammed. A jammed trigger can prevent the sprayer from activating. Also, verify that the on/off switch is in the correct position. It sounds basic, but it's easy to accidentally leave it off. Check your paint level. It may seem obvious, but ensure that there's enough paint in the bucket or container. An empty or nearly empty container will prevent the sprayer from drawing paint. Examine the suction tube and filter for any clogs or obstructions. A blocked suction tube can stop the flow of paint to the gun. Clean the filter regularly to prevent buildup. If your airless sprayer still isn't spraying, the problem might be with the spray tip itself. Remove the tip and clean it thoroughly. A clogged spray tip is a common culprit. If cleaning doesn't work, consider replacing the tip. Check the pump pressure setting. Ensure that the pressure is set high enough to spray. Insufficient pressure can prevent the paint from atomizing properly. Sometimes, the check valve can cause issues. Inspect the check valve for any signs of damage or wear. A faulty check valve can prevent the sprayer from building pressure. If none of these steps work, there may be an issue with the pump itself. If you suspect pump problems, consult the manufacturer's manual or contact a professional repair service.

Airless Sprayer Sputtering

Airless sprayer sputtering is another common headache. Let's figure out why your airless sprayer is sputtering. First, check the paint consistency. Ensure that the paint is properly thinned and mixed. Thick or lumpy paint can cause sputtering. Refer to the paint manufacturer's instructions for the correct thinning ratio. Next, inspect the spray tip for clogs. Even small clogs can disrupt the spray pattern. Remove the tip and clean it thoroughly. Make sure the suction tube and filter are clean and free of obstructions. A partially blocked suction tube can cause inconsistent paint flow. If the suction tube is clear, check for air leaks in the system. Air leaks can introduce air bubbles into the paint stream, leading to sputtering. Tighten all connections and fittings to eliminate leaks. Verify that the pump is primed correctly. An improperly primed pump can cause sputtering. Follow the manufacturer's instructions for priming the pump. If the problem persists, the issue might be with the pump's inlet valve. Inspect the inlet valve for any damage or debris. A faulty inlet valve can cause inconsistent pressure and sputtering. Sometimes, the pressure setting is too low. Increase the pressure gradually until the sputtering stops. Be careful not to set the pressure too high, as this can cause other issues. Check the condition of the spray tip. A worn or damaged spray tip can cause sputtering. Replace the tip if necessary. Finally, consider the temperature. Extreme temperatures can affect paint viscosity and cause sputtering. Ensure that the paint is stored and used within the recommended temperature range.

Airless Sprayer Spitting Paint

Airless sprayer spitting paint can ruin an otherwise perfect finish. When your airless sprayer spits paint, start by examining the spray tip. A worn or damaged tip can cause paint to spit instead of spraying evenly. Replace the tip if necessary. Check the paint consistency and ensure it is properly thinned. Thick paint can cause spitting, so thin it according to the manufacturer's instructions. Make sure the suction tube is fully submerged in the paint. If the tube is sucking air, it can cause the sprayer to spit. Inspect all connections for air leaks. Air leaks can introduce air into the paint stream, causing spitting. Tighten any loose fittings. Priming the pump correctly is crucial. Follow the manufacturer's instructions to ensure the pump is properly primed. If the pump isn't primed correctly, it can cause spitting. Look for any clogs in the system, especially in the spray tip and filters. Clogs can disrupt the paint flow and cause spitting. Check the pressure setting. Too low pressure can cause the paint to spit, while too high pressure can cause overspray. Adjust the pressure as needed. Sometimes, the paint itself is the problem. Old or poorly mixed paint can cause spitting. Use fresh, well-mixed paint for best results. Also, consider the extension pole. If you're using an extension pole, make sure it's properly connected and not causing any restrictions. Lastly, if you've tried all these steps and the sprayer is still spitting, it may be time to consult a professional repair service.

Airless Sprayer Pressure Problems

Airless sprayer pressure problems can manifest in several ways, from inconsistent spray patterns to a complete lack of pressure. When dealing with airless sprayer pressure problems, the first thing to check is the pressure control knob. Ensure it's set to the correct pressure level. Sometimes, it's as simple as adjusting the knob. Examine the pressure gauge to see if it's providing an accurate reading. A faulty gauge can give you misleading information. If the gauge seems off, it may need to be replaced. Inspect the pump for any signs of wear or damage. A worn pump may not be able to maintain consistent pressure. Consider having the pump serviced or rebuilt. Check the inlet and outlet valves. Faulty valves can cause pressure fluctuations. Clean or replace the valves as needed. Make sure the spray tip is the correct size for the job. Using the wrong size tip can affect the pressure. Refer to the manufacturer's recommendations for the appropriate tip size. Look for any air leaks in the system. Air leaks can reduce the overall pressure. Tighten all connections and fittings. Inspect the hoses for kinks or damage. Kinks can restrict the flow of paint and affect the pressure. Replace any damaged hoses. Sometimes, the problem lies with the power supply. Ensure that the sprayer is receiving adequate power. Insufficient power can cause pressure drops. Also, check the fluid strainer. A clogged strainer can restrict the flow of paint and affect the pressure. Clean the strainer regularly. Finally, if you've tried all these steps and the pressure problems persist, consult a professional for further assistance.

Airless Sprayer Clogged

Airless sprayer clogged is a common issue, especially when using thicker paints or coatings. When your airless sprayer is clogged, the first step is to relieve the pressure. Turn off the sprayer and follow the manufacturer's instructions to relieve any built-up pressure. Remove the spray tip and clean it thoroughly. A clogged spray tip is the most common cause of clogs.
