Oil paints are not dried through evaporation, because they contain no water. Instead, oil paints oxidise through a chemical reaction between the oils in the paints and the air. Placing an oil painting in direct sunlight or under low heat may help it dry slightly faster, but high heat will not effectively speed up the drying process for oil paints. You can, however, use a hairdryer, or other high heat source to speed up the drying times of acrylic and watercolour paints.

Things you need
Allow your painting to dry for up to an hour, to ensure any thick paint will not run when hit with the air.
Check to make sure your canvas is sitting firmly on the easel.
Turn on the hairdryer, on its hottest setting and with the least air blowing possible.
Hold the dryer a foot to a foot and a half from the canvas, and gently sweep it from side-to-side.
You will begin to see areas of the painting drying within minutes. Continue, until the entire painting is dry to the touch.
