The building texture set contains the 3 primary colors, Mars black, and 2 Titanium white for an endless mixing palette, 1 professional modeling paste, and 1 BASICS palette knife. As you begin to transition from BASICS to our professional line, experiement with our modeling paste. Used to build heavy textures on rigid supports and create three-dimensional forms. It dries to the hardness of stone, and can be sanded or carved when thoroughly dry. Can be handled like clay, if the top of the container is removed and some of the water is allowed to slowly evaporate, until it reaches a clay-like consistency. Adheres to any non-oily absorbent surface.
