With some patience and the right materials, you can turn out your own fountains by making molds of fountains you particularly admire. Because the molds are reusable, you can make many fountains from a single mold.

  1. Disassemble the fountain if it is built from multiple pieces. You'll need to make a mold for each piece.

  2. Clean and dry the fountain thoroughly.

  3. Mix equal quantities of the resin and catalyst of the mold-making polymer in a clean plastic container. Mix enough to cover the entire surface you want to reproduce.

  4. Place the fountain face-up on a level surface, if it's a one-sided design. If the fountain is sculpted on all sides, place it bottom-down in a level area where you can conveniently reach all sides.

  5. Brush or trowel a 1/4 inch thick layer of the mold-making polymer over the sculpted side (or sides) of the fountain. Be sure to wear rubber gloves for this.

  6. Allow the polymer to cure for at least one hour.

  7. If the fountain is sculpted on all sides, carefully make a cut through the cured mold running down the center of the mold on opposing sides of the fountain. This will allow you to remove the mold without tearing it.

  8. Carefully peel the cured mold from the front or sides of the fountain.

  9. Mix equal quantities of both parts of the mold-shell compound in a clean plastic container.

  10. Brush or trowel a thick layer the shell compound onto the back of the mold.

  11. Allow the shell to harden for at least 24 hours before using the mold.
