Decant is when you extract paint from a spray can. I just put one end of the straw right up to the nozzle of the can and place the other end into a bottle. The spray is minimized as it hits the sides of the straw. The paint simply flows and drips into the bottle.
Spraying from can is OK, but airbrushing is way better. If I use paint from factory bottled paint, I have to thin it out for airbrush use. If I use paint from spray can, it is good to go.
The only problem with decanting is, the paint is very volatile. You have to be very, very careful. If not, you can have the paint explode on you. If you plan to use regular hand held brush, you must allow the paint to acclimatize itself to the tempurature of the surroundings and release the energy that is in the paint (paint from a can is freezing cold). I wait about an hour for the paint to settle down. Some say 24 hours. In any case, you need to make sure you don't put the cap on the bottle as the paint will build up pressure like a shaken bottle of pop. Here's better explanation.
Decanting Spray Paint
When airbrushing, I wait only a few minutes to fill the reservoir of my top loading airbrush. I'm very careful not to touch the paint and put only small amounts in at first. You will see paint fizz and bubble. Put anything warm in the paint and it will fizz and foam over like root beer.
All the you tube videos show people taping pipettes or straws onto the spray can nozzle. I don't bother as I do this inside my paint booth. The overspray is minimal. The McD's straws fit right over the diameter of nib on the spray can's nozzle. I wear a good mask when airbrushing or decanting.
I hope this helps............ others can add to this if they wish. Everyone has a different way of decanting paint.
