  • Use as the binder for powdered pigments to make an inexpensive "student grade" extra- heavy viscosity (thick) gloss paint.



  • A marble "putty" made of marble dust and 100% polymer emulsion.
  • Used to build heavy textures on rigid supports and create three-dimensional forms.
  • Dries to the hardness of stone. It 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.
  • Drying too quickly causes mud cracking that is cosmetic, not structural.
  • When mixed with acrylic colors will act as a weak tinting white, while increasing thickness and rigidity.
  • Excellent substrate for acrylic paint, oil paint, oil pastel, oil bars, watercolor, graphite or dry pastel.


  • Apply with knife, brush, cake decorating tools, etc.
  • To prevent shrinkage cracks (mud cracking), dry slowly by covering loosely with plastic wrap. Apply less than 1/4" layer at a time. Mix with acrylic colors to produce a colored tinted paste.
  • When dry, Acrylic Modeling Paste may be painted with acrylic or oil colors.


  • Sculptural: Apply in thin layers allowing each layer to dry before applying next layer. If cracks appear, allow to dry and fill in with additional thin layer of Acrylic Modeling Paste.
  • Rigid support: Use straight from container.
  • Flexible Mix Acrylic Modeling Paste support: 50/50 with Gloss Gel Medium, Matte Gel Medium or Gloss Heavy Gel Medium.
  • Ground: Apply a thin layer of Acrylic Modeling Paste to rigid surface (i.e. wood), using a palette knife, trowel or roller. Let dry, then sand smooth. Repeat if necessary.Absorbent Mix 1/4 Acrylic Modeling Paste ground: with 1/4 LIQUITEX Acrylic Gesso. Apply with trowel or roller. Let dry, then sand smooth. Repeat if necessary.
