Clear Modeling Paste is an extremely thick acrylic medium. Containing large quantities of calcium carbonate and matting agent, this medium has a very short rheology, allowing for heavy impasto applications with superior peak and detail holding capabilities. Grey-white when wet, Clear Modeling Paste will dry semi-opaque, matte and can be tinted with Tri-Art Acrylic colours in any quantity. Remains flexible in thick, layered applications. When fully cured can be carved into and sanded.
