Liquitex Modelling Paste 473 ml (16 oz) — Marble-Based Sandable Acrylic Texture Paste

This 473 ml (16-oz) jar contains a marble paste formulated from marble dust and a 100% polymer emulsion that dries to a hard, sandable surface. Designed to combine with Liquitex acrylic paints and gels, it creates durable relief, can be carved after drying, and accepts additional paint layers. The paste is non-toxic, conforms to ASTM D4236, and is suitable for both studio and educational environments.

How do I create strong textures and sculptural forms with this modelling paste?

Apply straight from the jar for the stiffest, most stone-like results on rigid supports. Build up shapes in thin layers, allowing each layer to dry fully before adding more; once cured it sands and carves like a soft stone. For clay-like handling, remove the lid and let surface moisture evaporate until it reaches a workable consistency.

• Use a palette knife, trowel, or sculpting tools to shape while wet.
• Layer no more than 1/4" per application to avoid cracking.
• Dry thoroughly before sanding, carving, or painting.

Can I mix this paste with paint or other mediums?

Yes — combine the paste with acrylic colour to make tinted sculptural masses or to add body to paint. It intermixes well with Liquitex Professional Acrylic Colours and gel mediums; to retain flexibility on canvas or flexible supports, blend 50:50 with a gloss or matte gel medium.

• Tint with acrylics for coloured texture without compromising firmness.
• Mix with gloss/matte/gloss heavy/super heavy gels for flexible layers.
• Apply thin finishing layers of acrylic or oil paint once the paste is fully dry.

How do I avoid shrinkage or mud-cracking when drying thick applications?

Drying pace and thickness are the main factors affecting cracks. Keep individual layers under 1/4" and slow drying by loosely covering with plastic wrap to allow moisture to escape gradually. If cracks occur, wait until the layer is dry and fill with a thin additional coat of modelling paste.

• Limit thickness per coat to under 1/4" for best stability.
• Cover loosely to slow evaporation and reduce stress in the film.
• Repair cracks with subsequent thin layers; sand after complete cure.

Who this is for: Artists and educators who want to add durable, three-dimensional texture to mixed-media paintings, panels, or sculptural bases will appreciate this modelling paste. It's ideal for painters who work with heavy impasto effects, assemblage artists seeking a sandable hard surface, and instructors looking for an ASTM-conforming, non-toxic medium for classrooms. Use straight from the jar on rigid supports or modify with gel mediums for flexible substrates; tint with acrylics or overpaint with acrylic or oil once dry for finished, archival results.
