All of our stucco art is made of 2lb density styrofoam. We basecoat everything before it goes out. all sculotures need to be stuccoed with the color coat before it goes up on the wall. It’s already basecoated so you can use your color. If you don’t have a way to Stucco, we can use our sandpebble WHITE before it is shipped. We will charge you $50.for this.
