Acrylic and marble putty to build texture on rigid supports and create 3D forms. Key Features: 100% acrylic polymer and marble dust putty builds form and structure Dries to a very hard 'stone-like' opaque white matte finish that you can sand, drill or carve Can be used on its own, mixed with color or painted once dry Can be overpainted with acrylics, oils, watercolors, graphite or dry pastels Maintains paint adhesion, durability and archival quality How to Use: Can be handled like a lightweight clay - for best results remove the lid to let some of the water slowly evaporate until you get the texture you want For sculptural texture, build up in thin layers (each no more than a quarter of an inch thick), allowing each to dry. Dry slowly by covering loosely with plastic wrap to avoid shrinkage cracks To use as a ground - apply a thin layer to rigid surface with knife/trowel/roller, leave to dry, sand smooth and repeat if needed To make an absorbent ground, mix 1 part Modeling Paste to 3 parts Liquitex Gesso, apply with a trowel/roller, leave to dry, sand smooth and repeat if needed For paper-mache, soak paper in a 50/50 mix of Modeling Paste and Gloss/Matte Gel/Gloss Heavy Gel
