PianoTech Refinishers: I am looking for input from any of the refinishers in the group that work with water-base materials. I am having trouble with what I believe is commonly referred to as "orange peel". I am using Enduro polyurethane water-base hi-gloss clear-coat (numerous refinishers have indicated that it is the "best") with an Accuspray spray gun equipped with a #9 nozzle and a 0.043 tip (this is the combination recommended by Enduro for the product I am using). My sprayer is supplied with air by a 3-stage turbine. I am typically spraying with atmospheric conditions of about 80 degrees and 60% relative humidity. My understanding is that "orange peel" (my refinishing is coming out looking like the skin of a basketball - only finer grained - is this "orange peel") is caused by the material drying before it has sufficient time to flow out. It seems to me that 80 degrees is not too hot ( it is hard to get it lower in the summer), and 60% humidity is certainly not too dry. I am spraying within 6 - 8 inches from the object being sprayed. I am putting on what I think is enough material - it looks real wet and if I put any more on it will run (I know that for a fact!). What on earth am I doing wrong????? Anyone???? Any ideas?????
