Liquitex Modeling Paste is a putty made from 100% acrylic polymer and marble dust used to build texture and structural form. Intended for application on rigid supports, it dries to a very hard 'stone-like' opaque white matte finish that you can sand, drill or carve. Create impasto and 3D effects with Modeling Paste and mix in acrylic paints to introduce color. Once dry it can be painted with acrylics, oils, watercolors, graphite or dry pastels.
