I have a Graco Magnum DX sprayer with the 515 tip (0.015"). I also added another 25' 1/4" hose section at the sprayer and coupled that to the 3/16" 25' hose that came with the sprayer. I am painting my trim and doors in my basement. The sprayer worked well for the latex primer (Sherwin Williams PrepRite Classic). I set the sprayer to about half pressure (middle of full and prime/clean).
I then flushed the sprayer with water and then paint thinner and switched to the enamel (Sherwin Williams ProClassic Interior Alkyd Satin Enamel). At half pressure there was considerable streaking/tails in the paint pattern (4 or 5 main streams of paint). At full pressure the streaking/tails were better but still not very good. I then tried a
411 tip (0.011") but the spray with that was worse than the 515 tip.The enamel is considerably thinner than the latex so I thought the smaller tip was going to help but it did not. I have cleaned the gun filter and flushed the sprayer again.
Should I try using just the one 25' 1/4" hose or maybe just the 25'
3/16" hose? Should I try a 0.017" tip even though the max tip for the DX is 0.015"? Or is this sprayer just not going to work for the enamel?Thank you!!
