When combined with Lascaux Impasto Gel, Lascaux Artists’ Acrylics become thicker and pastier and thereby suitable for applying heavy impastos. Impasto Gel prolongs the drying of acrylics. It is also suitable as a strong adhesive for all types of collages and for incorporating materials, pigments, earth and sand. Used pure, it can be used to give bold textures when using brush or palette knife techniques. It dries clear, is tough, elastic and remains lightfast. Price per tub.
