Topic: paint clouds

[hymodyne]

I'm using a duplicolor acrylic lacquer to re finish my bike and helmet and I've run into the following problem; with the 5th or 6th thin coat on all parts, the paint applies evenly enough, but dries with cloudy areas that seem to dry more quickly than others. I will spray with clear, but would like to know if others have had this problem. 75+degrees, some humidity spraying outdoors.

nope, rattlecan over primer. I'm going to finish with two part sparymax in a can.

Lacquer and humidity = cloudy.  This is worse when the air is near the dew point.

What temps are you spraying at, and what time of day are you painting?

Also, you can speed up the drying and reduce the chance of humidity making it cloudy by putting the cans in warm water, (rotate the cans frequently in the warm water), and making the surface you are painting warm before spraying, as well.

Don't be painting right after a rain, obviously.

Let it completely dry between coats too...

Not talking hrs here....more like a day...

Whats happening is called "blushing" and will happen when humidity is high and the temperature is fairly low
The advice given so far if all good, these guys speak from experience.

Ah, humidity, the natural enemy of laquer! Repeat this mantra,

"I will not paint over 50% humidity,
I will not paint over 50% humidity,
I will not paint over 50% humidity,
I will not paint over 50% humidity," etc.

I bought a cheap humidity gauge/thermometer years ago, and it's saved me many thousands of dollars worth of paint. From experience, the darker the paint, the more at risk you are. Cheers, Terry.

This explains the blotchy blush on all my parts--my dark garnet metal flake painted parts. A warm front came in yesterday afternoon; It was clear yesterday but humid. Rain all day today. I'll wet sand and re shoot when conditions are better.
