Pebeo’s Studio Acrylics Modeling Paste is an opaque, white, heavy textured, matte finish, ready to use paste for creating reliefs and impasto, especially for creating dimensions. Opaque White Modeling Paste builds up solid forms and high reliefs. It can be tinted with acrylics or overpainted after hardening. It retains the imprint of the tool and can be sculpted, painted and sanded down once dry. After drying, it perfectly retains its volume and does not crack.
