Description:
 
100% acrylic polymer and marble dust putty build flexible form and structure.
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 colour or painted once dry.
Dries more slowly than other modelling pastes.
Gives minimal shrinkage.
Can be overpainted with acrylics, oils, watercolours, graphite or dry pastels.
Maintains paint adhesion, durability and archival quality. 
Direction
Apply with a knife or tool.
Tint with acrylic colour to make a coloured 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 the 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 the 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.
