Golden Fine Gel has a very small grit size to produce a velvety surface that is less coarse than the Golden Acrylic Ground for Pastels. A 100% acrylic gel, it can be thinned with water, tinted with acrylic paint for a colored ground and applied to any non-oily surface. The prepared surface will accept thinned acrylic or oil under painting. The viscosity is thinner and the surface finer than the Golden Acrylic Ground for Pastels. When brushed on it will impart a 'painterly stroke' to the surface.
