Urethane rubber masks make excellent costume pieces for use onstage or at a costume party. Urethane rubber is extremely durable, and can be moulded into nearly any shape. Although most urethane rubber masks are coloured during the moulding process, it is possible to paint a finished urethane mask. Whether you want to add painted details to your urethane mask or simply would like to change the mask's colour, you can paint a urethane mask yourself at home in an afternoon.

  1. 1

    Lay down several layers of newspaper to protect your work table. Clean your urethane rubber mask with a damp cloth and dry the mask thoroughly before continuing.

  2. 2

    Mix the two parts of your two-part liquid urethane rubber in a mixing container, stirring thoroughly with a mixing stick until the parts are completely combined. Mix just enough liquid urethane rubber to cover your urethane mask.

  3. 3

    Add urethane rubber pigment to the mixture to obtain the desired colour. Mix the pigment thoroughly. If more than one colour is needed, pour a small amount of liquid rubber into a separate container before adding pigment.

  4. 4

    Thin the pigmented liquid urethane rubber with white spirit. The consistency of the thinned rubber should be similar to milk.

  5. 5

    Apply the liquid rubber to the urethane mask with a brush. Let the mask cure overnight before handling.

Tips and warnings

  • Always ensure adequate ventilation when working with white spirit.
