Liquitex Professional Flexible Modeling Paste
This thick, matte, opaque gel painting medium allows you to create dramatic dimension and texture - blurring the line between painting and sculpture. It dries more slowly than other modeling pastes; it is workable while wet and results in a hard yet flexible surface. Use a palette knife, trowel, paintbrush, cake decorating tips and more to create a variety of effects. When mixed with acrylic colours, this paste will act as a weak tinting white while increasing the thickness and rigidity of the paint.
