Impasto gels are thick gels used to create heavy impasto textures and to give colours more body and volume. They may be used alone, mixed with, or painted over with acrylic colours to impart different sheens and textures to colours. Impasto Gels are flexible and will not crack even when applied in thick layers. They have excellent adhesive properties. painting_materials_lascaux_gels
