The unique Interactive formula of Atelier Interactive Artists' Acrylic Paint gives you more creative freedom than any other paint - offering the speed and simplicity of an acrylic paint with the option of more blending time when you need it. Simply paint in your usual way for traditional fast drying acrylic painting techniques and if you want more time to blend, use a water sprayer to keep the paint open and workable for as long as you like; EVEN DRY PAINT CAN BE REACTIVATED.
