- Wax the mold, appling 3-5 coats of Mold Release Wax to the mold where possible, using a stiff brush will help wax the details of this Mayan Calendar mold. Lightly buff the wax between coats, once it hazes.
- Apply a thin coat of Rubber Safe Form Release to the Mold just prior to casting the concrete piece.
- Various methods can be used to cast the concrete piece, though we strongly recommended that you use a very high strength, specialty concrete mix that is suited for this, such as the Surecrete XS-Precast Mix (sold here)
- View our Concrete Recipe section for tips on making your own 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.
- Any voids in the finished concrete can be filled using a Cement Slurry.
- 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 help break the suction holding the Mold in the concrete.
- Flip the mold over, setting objects around the rim of the mold so it's about 1/8" off the surface, and then leave it and allow gravity to help pull the concrete piece down and out of the mold.
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.
