Give your artwork a distinct, rough texture with Amsterdam Pumice Medium.
This gray pumice can be used directly from the jar on its own, painted over, or mixed with paint. Since the pumice medium is colored, mixing it with paint will affect the final shade. Amsterdam Pumice Medium is available in three textures: fine, medium, and coarse. Fine grains are often used to create backgrounds for further work with pastels, as the grainy texture significantly increases paint adhesion and color intensity. Pumice mediums are even used in scale model building to replicate textures such as concrete, stone, or gravel.
Tools should be cleaned with water. Apply at temperatures above 10°C and store in a frost-free place.
