If anyone tells you otherwise, like a hubby or sister or parent or neighbor, they are cluelessly wrong.
Edit: Prince, I doubt if she is talking about spray painting acrylic paint to do her acrylic paintings. So I gave her the right reply based on her usage of acrylic paint.
The state of California puts warning labels on damn near everything. They do so on acrylic paints with cadmium pigments because cadmium pigments are synthetically made and include metallic particles in the paint making process. The synthetically made pigments are completely harmless to 999999.99% of the artists who use solid acrylic paint. If is highly unlikely that the person asking here would ever become one of the 000000.01%, the one in a million nutcase, who would try to liquify solid acrylic artist paint down to be able to use as a spray paint.
As I said, California puts warning labels on everything to appease every overly cautious, overly protective mommy and daddy. No other state has such warning labels on artist acrylic paints except California. No one else is concerned about the one in a million nutcase user and misuser of the paint.
I gave her the right reply.
