2K problems - gun vs product?
Having problems with spraying 2K. I'm using Upol 2253 "system 20" with 2039 Standard hardener. I've sprayed 3 times and always gotten rough, dry texture. I've mixed 4:1 and reduced 10+% and sprayed at 29 psi trigger pulled but have raised and lowered pressure without improvement. From the beginning it doesn't seem to atomize particularly well but only gets worse. It doesn't look very wet going on. As you get near the end of the supply it sputters and seems like the gun is getting gummed up. I've even sprayed a piece of paper near to end just to make sure paint was coming out and the pattern looked OK. This doesn't seem normal. I'm using a new TCP global gun with 1.8 tip. I've heard good things about this gun, but never used it with another product so not sure if it's the gun. It just seems like the product is kicking over too fast. I'm only mixing up 600 ml at a time. By the time I'm done and put thinner in the gun to clean, I pull the trigger (air disconnected) and it takes a few seconds for paint to start coming out. It sands really nice but there is so much texture that you end up working more just to clean that up.
Any thoughts about what I'm doing wrong? Temperature was nice about 70 degrees.
Gonna try another product next time. Any recommendations for a similarly priced (hopefully hundred or less) gallon kit available for use in Kalifornia?
