It is better to use small portions.
With a brush apply the mask form a thin layer of ready mixture of two-component rubber. Wait until air bubbles and the rubber will begin to stiffen. Mix another batch of paste and hardener.
Cover the mask form with several layers of two-component rubber. Make sure that the last layer was done carefully and neatly.
Wait until dry mask, approx 24 hours. Then with a sharp knife cut holes in it for eyes, nose, mouth. Razreshite the mask with paints, glue additional items (if necessary). Make a well in the mask slit at the back and remove it from the workpiece.

From time to time stir the paint as it can flake. Rinse tools immediately after work, avoiding drying. Due to the fact that the paint has many properties of rubber, it can be given any shape, and it will not crack even when bending, stretching or exposure to frost.
