This is why I dont use spray. Only rollers and brushes.

Urethane paints contain isocyanates. Droplets react with moisture in
the lungs and soon lungs are covered with toxic plastic. And one of
the properties of good PU paint is that it wont come off, no matter
what and can withstand almost any mixture of chemicals for long time.
If one didnt have asthma before, after PU exposure one probably has.
If one had asthma already, no need to worry: breathing is now
impossible. My brother and my mother both have asthma. I am still
breathing nicely and  won't try my luck with this stuff.
