I have some background with brush finishing, but new to spraying. I originally finished several doors with Minwax Oil Based Spar Poly (brush) and was not completely satisfied with the results. I’ve always wanted to get into spraying and thought this would be the best project to learn. I bought a Titan 105 HVLP and seems to be a great setup. I sanded down my doors and people at sherman williams recommended spraying the same poly since it was already on there. I am having very inconsistent results. I set up a small booth in my garage with a dehumidifier and my hygrometer has been reading 50-60%. Some of the portions of the doors have been perfect, but others are getting hazy marks and gatoring is the biggest issue. The doors are 3 panel- am I getting too much product on where its gatoring? I’ve tried experimenting thinnning slightly vs thinning more and results seem to be slighty worse with more thinner. I’m considering trying a water based. Is this a better direction to go for self leveling and ease of working with? Secondly, I only have one gun at the moment. I know its ideal to have two separate guns, but would I be able to run water based through the same gun that I spray oil? I clean it thoroughly after each use. I’m starting to get quite frustrated, so any help would greatly be appreciated. Thank-you for reading and happy to be a member here.
