What is Winterizing?
Winterizing an airless paint sprayer is an important maintenance task that should be done at the end of every painting season to prevent damage to your equipment and ensure its longevity. To winterize an airless paint sprayer, you first need to flush out the entire system with a cleaning solution. This will remove any residual paint, debris, or contaminants that could potentially cause damage to the system.
Next, you need to protect your pump from freezing temperatures by either storing your sprayer in a warm place or adding antifreeze to the pump. You should also clean and store all of the parts properly, so they are protected from rust and corrosion throughout the winter months. With these simple steps, you can prolong the life of your airless paint sprayer and ensure that it is ready to use when you need it next season.
Remember, taking the time to winterize your equipment is an important investment in its long-term health.
Preparing for Cold Temperatures
Winterizing is the process of preparing your home and belongings for the cold temperatures that come with winter. This involves a range of steps, from insulating your pipes to sealing your windows and doors. The goal of winterizing is to help keep the warm air inside your home and the cold air outside, which can help reduce your energy bills and prevent damage to your property.
One of the first things you should do when winterizing is to inspect the exterior of your home for any cracks or holes. These can let cold air into your home and make it harder to maintain a comfortable temperature. You should also check the insulation in your attic and walls, and consider adding more if it is insufficient.
Other steps may include covering outdoor furniture and storing your garden hose inside to prevent it from freezing and cracking. By winterizing your home, you can ensure that you stay warm and comfortable throughout the winter months.

Why Winterize an Airless Paint Sprayer
Winterizing an airless paint sprayer is a crucial step to ensure that your expensive equipment remains functional and free from any damage during the chilly winter months. It basically involves removing all the fluids from the pump, gun, and hose of the sprayer, lubricating its parts, and storing it in a dry and warm place. The purpose of winterizing is to prevent the formation of ice, which can expand and damage the internal components of the sprayer causing leaks or blockages.
By taking this proactive step, you can increase the lifespan of your airless paint sprayer and avoid costly repairs. So, don’t overlook the importance of winterizing your airless paint sprayer and make sure you do it before the temperature drops below the freezing point.
Steps to Winterize an Airless Paint Sprayer
If you own an airless paint sprayer, it’s important to know how to winterize it properly to avoid damage and keep it in good working order. Fortunately, the process is fairly simple and can be done in a few easy steps. First, you’ll need to flush out any leftover paint and clean the machine thoroughly.
Then, you’ll need to add a winterizing solution to prevent any remaining water from freezing and damaging the pump or other components. Finally, store the sprayer in a dry and warm location to ensure it stays protected from the elements. By following these steps, you can help extend the lifespan of your airless paint sprayer and avoid any costly repairs down the road.
Step 1: Clean the Pump
Winterizing an airless paint sprayer is an important step towards maintaining your tools and prolonging their lifespan. The process involves a few critical steps, and the first one is to clean the pump. Before you begin, make sure you have all the necessary tools for cleaning, such as rags, cleaning solution, and a brush.
Start by removing the gun and tip from the sprayer and wiping down the exterior with a rag. Next, remove the filter housing and inspect it for any dirt or debris. Cleaning the filter regularly ensures that your pump is not clogged and that you can achieve consistent pressure.
After cleaning the filter, flush the pump with water or a cleaning solution using the prime/spray valve. Make sure to drain any remaining liquid from the sprayer and let it dry thoroughly before reassembling. By taking the time to clean the pump properly, you can prevent damage to the internal components and ensure that your sprayer is ready for use when you need it.
Step 2: Flush the System
When it comes to winterizing an airless paint sprayer, step #2 is crucial: flushing the system. This process ensures that any remaining paint is removed from the sprayer, preventing it from freezing and causing damage to the equipment. To do this, start by removing the spray tip and guard, as well as any filters or screens.
Then, turn on the sprayer and run water through the system for at least 5-10 minutes, until the water runs clear. Be sure to flush all the hoses, as well as the gun, trigger, and any other parts. Once you’re finished, remove any excess water by running a bit of mineral spirits or pump armor through the system.
Taking the time to properly flush your airless paint sprayer before storing it for the winter can help prolong the life of your equipment and ensure that it’s ready to go when you need it next spring. Don’t skip this important step in the winterization process!
Step 3: Lubricate Moving Parts
When winterizing your airless paint sprayer, it’s important to lubricate all the moving parts properly to prevent any damage. This step is crucial for maintaining the longevity of your machine. The first thing to do is to clean the sprayer thoroughly to remove any traces of paint residue.
Once you’ve done that, apply a thin layer of oil to all the moving parts such as the piston, packings, and valves. You can use spray lubricants or a paint sprayer oil that’s specially formulated for airless sprayers. Rub the oil evenly using a soft cloth or brush and allow it to sit for a few minutes before wiping off any excess oil.
Lubricating the moving parts will prevent them from rusting and sticking, ensuring smooth operation when you need to use your sprayer again. Don’t forget to check the manual for specific instructions on which lubricant to use and how often to do this maintenance. A well-lubricated airless paint sprayer is a happy sprayer, and it will save you time and money in the long run.

Remember to always clean the sprayer thoroughly before storing it for the season, remove all leftover paint, and lubricate the pump with the recommended oil. Taking these steps will prevent freezing and damage to your equipment during the colder months.
Additionally, consider investing in a storage fluid to further protect your sprayer’s internal parts. By following these simple steps, you can ensure that your airless paint sprayer is ready for use when you need it again in the spring.
