Hi guys,
I was painting a practice panel over the weekend, just to see if I liked a particular color. The surface was primed with 2K and sanded lightly. I was spraying an acrylic enamel of 8 parts color, 1 part hardener, 2 part reducer as called for on spec sheet. I was using a regular (not HVLP gun) touch up gun at about 40-45 lbs. pressure. As I was going over it with a second coat, I noticed scores of tiny air bubbles forming on the surface of the panel. I continued spraying since this was only a test for color, but when the panel dried, the bubbles of course remained in the finish.
Thank goodness this was only a color test and not on something I was finish spraying. I've done some painting before but not had this happen. What was the cause? Too much pressure? Poorly mixed paint? Defective gun?
When I do decide on a color, I will spray with a new HVLP gun that will have a digital regulator attached at the handle of the gun.
Obviously I want to avoid such a disaster later. Your help and advice are greatly appreciated.
Yours,
Jim
