DIY Steps To Clean An Airless Paint Sprayer
It is now time to clean out the airless paint sprayer to flushing fluid. Some of the steps that you need to use to help with this include:
1. Set Up Your Buckets
You will need to set up a few buckets to make sure they have the right solutions in place for flushing fluid.
You will need to pick a paint sprayer cleaner or a solvent for flushing fluid that works for the type of paint inside of your airless paint sprayers.
Keep one bucket filled with water and soap, one with the chosen solvent, and one that is empty so that you can pour the dirty liquid cleaner into that later.
2. Clean Out The Paint
You will need to place the suction spray hose of the airless sprayer into an empty bucket for flushing fluid. Aim it at the empty bucket.
Push the prime mode and the spray mode in order to get all of the remaining material out.
Add more water or paint thinner or mineral spirits to the oil paint container for flushing fluid through too. Continue pushing it in and out until the liquid comes out clean.
3. Cleaning The Sprayer Filters
The filters are important to your work in this sprayer. There will be two to three filters on these airless paint sprayers.
Unhook these from the air spray gun and add them into a bucket of soapy water or a solvent mixture or paint thinner or mineral spirits for flushing fluid. Never place the entire spray gun inside.
Let the filters sit there for five to ten minutes. After that time, remove them from the solvent and scrub with a soft bristle brush to remove the paint.
You can add them back into the solvent for longer if the paint is really stuck in the spray gun filter.
4. Clean The Nozzles
This is probably one of the most tedious parts of the process. You may want to use an old toothbrush, pipe cleaners, and a needle to get all the paint out.
Place into the solvent to make sure that it has a way to release the paint. Then scrub with the toothbrush until the paint is gone.
Run more water and solvent through to help rinse out the paint flow when necessary. Look through the nozzle and see if you notice a small amount of light showing through. It is clean when that is done.
When these are all cleaned off, gives the airless spray gun a good scrub on the outside and then wipe everything dry. Then, use the user manual to help put it all back together again.
