freedhardwoods Posted September 24, 2020 Report Share Posted September 24, 2020 I don't think our spray system has been atomizing right ever since we got it. Whatever we are spraying hits the work piece looking slightly textured, but has always leveled out to look good. About 4 months ago, we sprayed a kitchen with Axalta white pre-cat lacquer and it came out fantastic. Between then and now we sprayed Axalta pre-cat clear over stain and it worked great also. Over the past week, we have been trying to spray gray and can't get it to work right consistently no matter what we try. With the white, we mixed 8 oz of butyl acetate per gallon. The clear we sprayed undiluted. Our supplier has told us all along that diluting too much would cause problems, and I was trying to follow his recommendation on thinning. This gray lacquer when thinned with 8 oz of BA would go on very textured, set almost instantly, and be dust flying sand-able in 60 - 90 seconds. After much experimenting, I was able to get some pieces to come out good while others would set before they leveled out by mixing 20 oz of retarder per gallon. It looks terribly thin, but no runs on a vertical surface. The last attempt I made, the first door looked great, but by the 4th door 2 minutes later, it would not level out. We were against a deadline and I had someone else spray the last few pieces. I think there is more than one issue going on, but I'm still a beginner at finishing. Any ideas?

Chestnut Posted September 24, 2020 Report Share Posted September 24, 2020 Whole lot there that is way over my head. Have you reached out to Fuji to see if they have any opinions on what is happening? Quote Link to comment Share on other sites More sharing options...

Chet Posted September 24, 2020 Report Share Posted September 24, 2020 I contacted (emailed) fuji for some information on a paint product I wanted to spray. I attached the tech sheet for the product and asked my questions. I did take them about a day to get back but it was good information when they did. 1 Quote Link to comment Share on other sites More sharing options...
Popular Post freedhardwoods Posted September 25, 2020 Author Popular Post Report Share Posted September 25, 2020 It sounds like I need to talk to Fuji. The only thing I can think of changing now is going to a bigger tip, even though the chart included with the sprayer says to use a 1.0 or a 1.3. That will have to wait now because my paint supplier offered to let me have one of his reconditioned spray systems, make sure it is working for us, and not have to pay for 12 months. It's a $3000 (new) system for $1200. The gun alone costs $800. Merkur 15. It's working great so far. 3 Quote Link to comment Share on other sites More sharing options...
