Light Dimensional Ground. A white, lightweight paste that spreads like frosting, Light Dimensional Ground can be applied smooth and thinly, or built up to create ridges, peaks and other interesting textures. Use on a wide variety of surfaces, including board, canvas, wood, panel, and paper. May be wet sanded. The extremely absorbent surface of Light Dimensional Ground allows washes to spread quickly, while accommodating fine lines and detail as well. Dropping color into lightly wetted areas creates beautiful blooms.
