I have just bought an dual-action air brush and on the first push of the button paint comes out then the flow of paint stops . Why is this happening and how can I fix it?
Sounds like the paint is drying/clogging as soon as it hits the nozzle. Let me guess…acrylics.
Try increasing the pressure.
Try thinning the paint more.
Make sure your hose isn’t crimped.
Test the system with plain water to see if it’s the paint or the hardware.
No not acrilics enamels at this stage. but will try your suggestion anyway. thanks
