    Default PRESS AIRBRUSH TRIGGER GETTING PAINT??



    by Don Johnson


    When you are new to airbrushing a problem like this can drive you to the brink of throwing the airbrush away.

    Relax; take a deep breath it’s just paint. You are wanting to learn to airbrush as a way of releasing your creative side and relaxing please don’t lose site of those goals.

    PROBLEM

    You push down on the trigger of the airbrush and paint is applied (sprayed) even though you are not pulling back on the trigger.


    Pictured above are the resulting splats you might get if the above problem happens to you.

    *** This is the number one reason you ALWAYS test your airbrush before going to spray on your intended painting surface. You want to make sure your airbrush is functioning properly before one of these slats ruins hours of hard work.


    SOLUTIONS





    Pictured above the working end of my airbrush and as you can see the needle is protruding out the front of the airbrush.

    For this problem to occur your needle is not seating in the nozzle of the airbrush correctly.

    Loosen the chucking nut and make sure the needle is all the way forward in the airbrush, seated in the nozzle.

    Careful push the needle toward the front of the airbrush while rotating the needle, you will feel the needle come to rest inside the nozzle. Do not force the needle into the nozzle as you will ruin your nozzle.

    Try the airbrush again if still is spraying paint when you push down the the trigger move on down the list here.





    Pictured above I have taken the needle out of my airbrush and will inspect it for dried paint on the tip which might keep it from seating in the nozzle correctly. Also check to see that the needle is not bent. Clean the needle, lube it and put it back in your airbrush.

    Try your airbrush if the problem is solved cool if not move on down the list.







    Pictured above I have removed the nozzle from my airbrush to inspect it. Make sure there is not dried paint inside the nozzle that is keeping your needle from seating properly, make sure the nozzle is not deformed or cracked. Replace the nozzle if you find it to be cracked or deformed. Clean the inside of the nozzle out with a airbrush tip cleaning kit, cutting touch tip cleaning tool, straight pin just be careful not to ruin the nozzle in the process. Soaking the nozzle in cleaning solution might be helpful also.

    Try your airbrush now after going thru the above steps it should work correctly. If not post in this thread we will try and help you further.

    Carelesser, it sounds a git like you are not starting and ending every stroke or pass with the airbrush with the air on. By not ending your stroke with the air on, you end up with a tiny bit of paint sitting on the end of the nozzle, just waiting to splat the next time you apply the air pressure.

    If you just push the trigger down for air only, are you getting any paint coming out?

    Is the tip of the needle nice and straight and clean?

    Carelesser, it sounds like you understand the explaination.
    Yes, if you have the needle and nozzle cap removed, and you pull the needle back, then push it forward again, the little drop of paint will show up on the end of the needle. Because you didn't have air on, the paint just got pushed out of the tip of the nozzle by the force of the needle coming forward. The same adhesive quality of the paint that makes it stick to your work surface also makes it want to adhere to the tip of the needle when there isn't any air flowing past to atomize it.

    So again, for all airbrushers, always start and end your strokes with the air ON, this keeps you from getting that little blob of paint sitting there, waiting for the next time you release air to go SPLATT on your painting.

    Keep your brushes clean and well maintaned both inside and out. Like the engine on a car, a clean brush lives and runs better when it is kept clean and well taken care of.

    Lube is good, but using the improper stuff will cause a lot of heartache.

    Try this:
    Airbrush Super Lube

    There are lots of other places that sell this type of airbrush lube, so, search the net. Also, keep in mind that this is intended to be used sparingly... lube can potentially contaminate paint if you're not careful.

    When you do the inspection of your nozzle for paint, also be on the lookout for distortions and cracks or splits, these can keep your needle from seating/sealing properly when installed. Also do a careful inspection of the needle itself, if it has distortions, bends, kinks, or faceted/flat surfaces it will keep the needle from seating properly in the nozzle. Keep in mind that the needle and nozzle are designed to match each other in shape and dimension, so when one or both parts are altered by paint, debris, or distortion the working relationship between them is altered or gone, sometimes a little bit, sometimes completely.

    New guy here! I have the same prob with my cmc+. I cleaned it, inspected evry piece. Do you think i might have the wrong needle size in comparison to the nozzle? i believe i have a .23 needle. I press down for air and paint comes out. i have a sprint compressor as well...sucks!!! I 'm going back to my big household compressor. I'm thinking that the nozzle is ruined. I put a new needle as well. Thanks Daniel

    If you are just pressing the trigger down (for air) only, and you are getting paint coming out of the tip of the brush, then the first thing I would do would be to loosen the needle chucking nut, press the needle forward into the nozzle firmly, and give the needle a twist or two. This helps the needle seat properly in the nozzle.
    Make sure you tighten the needle chucking nut back up!

    If you are still getting paint coming out when you are only pushing the trigger down and not pulling it back, then I would do a cleaning again, then do a careful inspection of the needle tip, and the nozzle, both inside and out.

    Personally, I wouldn't have chosen a Micron as a starter brush, but if that's what you have then that's what you have to work with. I doubt it came with the wrong needle or nozzle size, but it's possible.

    NO!
    While the Teflon sprays and lubes may work well for firearms, they can reak havoc with airbrushes or spray guns.
    Keep in mind that anything you introduce into your airbrush will potentially be mixed with the air, the paint you are spraying, or both. So the lubricant needs to be neutral and used minimally at the most.

    I've been using the Paasche AB for sometime and wanted to try the Iwata CMC Plus. I think i'm going back. But tried just about everything to correct the problem. I might buy a new nozzle for it. Thanks Fontgeek

    PM me if the nozzle doesn't help. We'll figure something out to get you back on the road.

    The Paasche AB is a wonderful brush, it's capabilities are amazing, however the hassles that normally come with it make it more problematic than most people are willing to deal with.

    If you are looking for a more general use brush that can still do some good detail, then I would look at the Grex XG or XS, or the Iwata HP-Cplus.

    Eskimoe1, do you have a strong magnifying glass or jewelers loupe you can use to do your inspection on your airbrush and parts?
