The most common mixture used for walls consists of 3 parts sawdust, 2 parts sand and 1 part cement. For smaller panels, 4 parts sawdust is usually satisfactory. The sawdust should be from hardwood - which is low in tannin, gums and oils - for the best results. Most people mix the ingredients in a large, shallow metal tray using hoes or rakes. Only enough water to activate the cement should be used.
