Hi,
I'm painting w/ a Fuji 3 stage HVLP gun (first time user) on MDF. I bought some Satin Urethane Enamel (water based). I'm spraying it on MDF.
I have a 1.3, 1.5 and 1.8 tip. The 1.5 hasn't arrived yet. Yesterday I tried the first coat w/ 1.8 and thinned the paint to take about 30 seconds on the viscosity cup (about 4:1).
The paint went on pretty heavy (reminded me of airless) and when I sprayed vertically it had a few runs. Obviously, my technique is going to take some practice (speed, distance, fan size, etc). However, if I have "too thick" issues, should I be watering down the paint, reducing tip size or something else? The manual notes that w/ water based the needle should be all the way out to avoid confusion. According to the manual, it sounds like I'm not thinned out enough? I'm not sure when tip size comes into effect.
I'll be practicing more today.
Also, the satin sheen seemed to be matte when it dried. Is this generally a 1st coat on MDF issue or can I thin the paint "too much" and cause sheen issues?
