With most paints coloring foam board can be a hassle. Usually the board curls unless you paint both sides. Design Master COLORTOOL™ Spray add brilliant color to foam board without any curl. And, you only need to spray one side!
On large pieces, start spraying using the basic technique but begin at the edge closest to you and spray away from you. This method keeps a fresh edge as you spray into the overspray, resulting in a smooth finish. Add highlighting interest to the form by using a complimenting color misted along the edges.
