Acrylic paint is a safe option when it comes to fine art. Oil paints and turpentine can be dangerous materials to use, but acrylics are water-based and come out of brushes and other materials easily. In thin coats, acrylic paint dries very quickly, sometime within a few minutes, but if you need to speed up the process, you can dry acrylics in a few easy steps.
Plug the hairdryer into an outlet near the painting you wish to dry.
Hold the hairdryer 12 to 18 inches away from the surface of the painting and turn it on low.
Sweep the hairdryer over the painting's surface until the entire painting has been exposed to the heat. Depending on the size of the painting, this should take no longer than a minute.
