Winsor & Newton Professional Acrylic Medium, Modelling Paste is lightweight and flexible so it doesn't shrink or crack. Increases opacity, body and structure and is ideal for carving, sanding and building extreme textures. It can be used to build up depth in layers and either overpainted when dry or mixed with color. Dries to an even matt finish.
The Mont Marte Dimension Acrylic Colour has ultra-thick consistency and can be applied with a brush, palette knife or shaper to create especially exaggerated texture effects.
