Spraying Carvings without Drips
Question
Forum Responses
From the original questioner: The Kremlin does not seem to feather well. I'll give the pressure pot a try. From contributor U: What are we spraying - doors, trim, panels? What approach are you using to spray? Are you spraying at an angle or straight on? From the original questioner: We are spraying columns with carved capitals and fascia that is deeply carved also. Yes we tried spraying on an angle and straight on but some of the lower relief areas received very little finish. From contributor K: We've had that problem on highly carved and pierced pieces. The favorite workaround has been to take a smaller touch-up style gun and hit those areas first from whatever angles minimize the air-trap. Then we come back with the production gun to hit the rest. Takes time but sure beats sanding drips. From the original questioner: I hear you about the drips! I do have a gravity fed cup gun I could try for the detail work. Here is a photo of the carvings we are having trouble with.  Click here for higher quality, full size image Below is the fascia. The gravity gun works a little better then the Kremlin but still hard to get the low areas without having it running off the high points. Any other tips are appreciated.

Build the Clawlok - like on the fascia, pass tilted up, pass angled left, pass tilted down, pass angled right. If things look kind of wet, wait for the solvent to flash a little before the next pass. If you have air control, keep it as soft as you can to minimize the air trap. From contributor G: Are you trying to hide the wood grain? From the original questioner: Yes it is a pigmented finish. If it was mine it sure wouldn't be though!

Have you tried to reduce material on the pump and use a tiny tip? I can always break out the Sata and dial down the pressure, but I'm spoiled with tip changes on the Kremlin! From contributor R: I’m not sure if anyone else does this but I like to give a carving like that a real good sanding first before the finishing process. Pay particular attention to sharp edges as the sharpness will actually repel a finish and cause a bridging on the flats. Sometimes the end grain can be an issue on a carving be it a machine carve or even a hand carving so if there is any sort of roughness, a good sanding will help yield a good looking finish.
From the original questioner: I think if I buy another tip for the Kremlin I will need to hire a security firm to guard them all! I do have a 06-092 tip I have tried it and it is a better then the 09-112. I think I will try the gravity gun with the air down low first before looking at the 04 tip. I did sand a bit but maybe could break the edges of the fine details a bit more to open them up.
