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.

However, it is not necessary to use for painting furniture, floors, window frames and doors.

Best will be the paint on puttied and polished surface, but don't forget to clean it from dust formed in the process of grinding.
If you want to paint the rubber paint on the surface previously covered with oil or alkyd paint, sand it to a matte state. Wash with soda solution or sodium phosphate, rinse with water, cover with universal primer and air dry.
Open the jar of paint and mix it thoroughly. In General, to dilute the rubber paint is not desirable, but if it is strongly thickens, it can be made more liquid with water.

Apply on a dry surface the first layer of paint with a roller, brush or spray (ambient temperature should not be below +5 degrees). Wait for complete drying of the layer (from 30 minutes to 3 hours, depending on humidity and temperature) and apply a second coat. In General, to create a smooth durable surface is required 2-3 coats.
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.
