Trying to put a second coat on a dresser I've just finished and the Wagner HVLP conversion gun NVC Model won't spray. I'm using a water based polyurethane that I've used before without trouble.
I've read the troubles shooting section of the manual and replaced the valve but still no luck. Noticed that when I pull the triger without the can secured but the pickup nozzle can be seen, the fluid in the can bubbles. Which I thought strange since this is the pick up tube for the spray material.
I've disassembled it about five times and looked for blockages but can't see anything out of the ordinary. Thought I've doe a decent job cleaning it after every use, but apparently something is amiss. The Gleem company where I purchased it is down for the day so unless someone can help me, I guess I'm done finishing for the day.
In a follow up post I mentioned tht I found the suction tube was clogged with a small spring. Checked with Gleem and they said there is no spring or valve in the suction tube -- just a tube. And the spring I found is definitely not a part of the gun.
Interestingly enough, he mentioned that they have other reports of foreign objects being in paint that have caused similar clogs. First time report of a spring however. Guess the lesson here is that it would pay to strain your paint or finish thorugh some cheescloth before pouring it in the cup. In other words don't assume the manufacturer's quality control is infallible.
Thanks to all who posted trying to "unclog a clog."
