    Mold Use:

    Mold Setup:

    • Wax the mold, appling 3-5 coats of Mold Release Wax to the mold, lightly buffing between coats once it hazes.
    • Apply a thin coat of Rubber Safe Form Release to the Mold just prior to casting the concrete piece.

    Concrete Casting: 

    • Various methods can be used to cast the concrete piece. View our Concrete Recipe section for tips on concrete mixes.
      • GFRC: Cement and fiberglass is sprayed on and hand packed into the form and around the sink.
      • Wetcast: Oatmeal consistency concrete is placed in form and vibrated. 
      • Hand Packed: A drier concrete mix is hand packed into the Mold. A second step after de-molding will fill the voids with cement slurry, usually of a different coloring.
    • Any voids in the finished concrete can be filled using a Cement Slurry.

    Mold Removal:

    • If the steps above were followed for the Mold Setup, then most Molds will usually pull out of the concrete with little effort.
    • If the mold is difficult to remove, try:
      • Compressed air shot around the Mold rim will break the suction holding the Mold in the concrete.

    Mold Clean-up and Care:

    • Clean Mold with a sponge after each use. Any dried cement residue can be removed with a scotch-brite pad (as outlined above in the Mold Setup section. A light muriatic acid wash (20:1, 20 parts water to 1 part muriatic acid) can also remove cement scale.
    • Waxing and buffing the Mold after cleaning it use is recommended to protect the Mold until its next use.
