Liquitex Flexible Modeling Paste is a matte, opaque preparation of marble dust and polymer emulsion.   100% acrylic polymer and marble dust putty builds flexible form and structure. It dries more slowly than other modelling pastes to a hard, yet flexible surface. Dries to a very hard yet flexible opaque white matte finish, on supports that may be subject to some movement. Can be used on its own, mixed with color or painted once dry. Dries more slowly than other modeling pastes. Gives minimal shrinkage. Can be overpainted with acrylics, oils, watercolors, graphite or dry pastels. Maintains paint adhesion, durability and archival quality. Recommended for use on supports with occasional flexing. How to use Fully intermixable with all Liquitex products. Apply with knife or tool. Tint with acrylic color to make a colored paste. Can be handled like 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. If cracks appear, allow to dry and fill in with another thin layer of paste. Overpaint once dry with acrylics or most other media. To use as a slightly flexible 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. Can be mixed with acrylic-compatible powdered pigments or aggregates -Do not use with any non-acrylic compatible media. Drying too quickly will cause cosmetic (not structural) cracks. Use with Liquitex Heavy Body Acrylic and Liquitex Soft Body Acrylic colours.
