HELP NO GLOSS

Sounds like either one of the cans (the last one used) was bad or the two brands didn't like each other.  Your friend should be able to use some Clear Gloss to rectify the problem though...

Not quite enough info to go on... 
Such as what paints were used?

Just because the paint was gloss, doesn't mean they were the same type of paint.
You can have gloss and semi-gloss - enamel, acrylic, and lacquer.

Different brands of the same type of paint can use different thinning agents amoung other things.


 

outside in the mid 80's,what was the humidity like?.too high and it will cause the gloss to dry flat or milky white

Sometimes this can be caused by insufficient mixing. The pigment is heavier than the carrier and settles out and is in itself, not glossy. If the can is not shaken thoroughly before spraying, you will get a blast of paint that contains more pigment than carrier.

A number of things can be happening, several already mentioned:

1. Insufficient mixing. Shake the cans for one minute (at least, and I mean SHAKE) after the agitator ball is heard. Shake frequently between passes.
2. Too much distance between target and nozzle. Move closer. See below.
   
3. Too much temperature differential between can contents and spraying environment. If the can came from an air-conditioned house, or even a basement, into mid 80's in sunshine, the reducer in the paint mixture in the can will operate a little too efficiently, causing a finer mist of paint droplets than would otherwise occur. These will dry even more rapidly than usual, reach the surface partially to completely dry, and produce anything from a flat finish to a semi-gloss finish. Let the can come to ambient before spraying.
   
4. A temperature in the mid 80's, especially with low relative humidity, can produce the same results even if the can is near ambient temperature. Also, the can will cool as you spray, leading to the situation described in (3) above. Spray in cooler conditions and/or move closer to the target.
   
5. Hot target surface(anything over 75°F). Work in the shade!
6. Old paint. Possible, but unlikely since you used two different cans.
   
7. Mislabeled paint. Again, unlikely since you used two different cans of different brands.

Hey guys,

Thanks for the info and I will let him know the input from all of you.

Thanks for responding and the forum does work!!
