Liquitex Modeling Paste is a thick acrylic gel, blended with marble dust, which produces a strong & durable texture. Posessing an extra heavy body, while being very opaque, Liquitex Modeling Paste is perfect for building heavy texture on rigid supports and creating 3D forms. Liquitex Modeling Paste is an excellent substrate for acrylic & oil paints, as it adheres to any non-oil & absorbent surface.
