I would like anyone's ideas on this problem. I am spraying cabinets with SW Kem Aqua Plus which I have done many times in the past with excellent results. This time I am getting many tiny bubbles, some pop and leave a tiny crater so they are definitely bubbles not detritus. It happened yesterday with the Kem Aqua surfacer which I solved today with a very light sanding with worn 220. I initially blamed the product because I had just ran to the Monroe SW to buy some as I was out of stock. They had put the can in the shaker before I got there so I thought that might be the problem. However, I just applied the topcoat (low gloss white) and it it doing the same thing just not quite as bad. I have had that can for a while and it was only stirred. Here are the other details:
Done in my spray/finishing room with powerful exhaust. The air comes through my refrigerated dryer.
Devilbiss Finishline FLG4. I think it was a 1.3 tip
My on gun regulator bit the dust so I went this morning and got a new one. Running between 19 and 20 at the gun.
I dialed the volume back so as to get a thinner film. It helped some but still some bubbles.
I read that SW recommends using Butyl Cellosolve as a retarder, thinner if this happens but I would like to avoid that if possible. I also read it is not the safest chemical. However, I do use a supplied air respirator. Thanks.
