FrogTape and Scraper Discussion

issues um there could be outgassing of on the substrate something underneath there could be a reaction with it one coating going over the top of the another coating i've seen that's caused um your blistering there's somebody you know here that micro bubbling is talking about microwaves yeah that's the next thing what causes teeny tiny micro bubbles when using the airless sprayer is it low temperature so i actually had um i've had a lot of people ask that question in the past and i never experienced it and probably about six months ago i experienced it when spraying cabinets and um it was very frustrating and so i was getting a micro bubbling on it and you know i checked my paint make sure you're not stirring your paint i'm creating bubbles in the paints but what i eventually um diagnosed to that i started adjusting the distance that i was spraying and the pressure i was spraying and i increased my pressure a little bit on my hairless sprayer i cl um close the distance to my spray gun to you know the doors i was spraying and it eliminated the micro bubbles and the only thing i can think is the distance i was too far away and it was allowing the coating to um create micro bump micro bubbles because it's going through the atomization process going through the gun in the tip and it was getting micro bubbles in the air as his as it was hitting the surface because there was too um too large of a distance between my gun and the surface that i was spraying so i closed the distance i'm turned up the pressure a little bit and there was no more micro bubbles so it's kind of interesting i thought it was originally related to you know outgassing you know of the surface now i have run into um lacquer so we did lacquer under coder on a bunch of doors it was completely cured um it was they've been cared for over a month we came back and top coated them with multiple 2k polys testing them and it was getting micro bubbling in um on in the top coat and it was it was interesting it was a reaction with a 2k poly over a lacquer undercoater and um it would bubble across the entire surface micro bubbles and we couldn't get it to stop and the only thing i would suggest is don't put a 2k poly over a lacquer undercoater i i didn't see an issue ever with ben which is a shellac based you know product but um we used a it was sherwood high build lacquer undercover that was reacting with our 2k poly
