  • Product Specifications:
    • New design, no built-in drain flange on this mold!  So you can use one of our removable Drain Flange rubber plugs to create the drain size you want on this mold, and change it when you want, or even create a custom 'slot drain' on the sink using pieces of plexiglas or foam!  You can also use your actual metal drain on the mold for a perfect fit! (just silicone your metal drain piece to the mold, and then wrap some thin foam around it and some packing tape, then cast the concrete, and after remove the metal drain to finish/seal the concrete).  Select Bathroom or Kitchen when you order this mold and we'll include that style Drain Flange plug with the mold, and if you want to order the other size plug as well you can do that here:
    • Our SDP (Super Durable Polyurethane) Line of Sink Molds are made from the highest grade Polyurethane Rubber.  Won't chip and crack like fiberglass, and much easier to get out of concrete after casting. A lifetime of reusability.

    Product Description:

      • Each Sink Mold comes with a reusable rubber drain flange (you select Bathroom or Kitchen size above)
        • Oversized, Extra-Deep kitchen drain hardware designed for thicker concrete sinks sold here (up to 1-7/8" thick sinks!)
        • All our Molds have Lifetime Guarantee against defect. This Guarantee does not cover misuse of the Molds (Dropping the Mold, Prying the Mold out using a screwdriver, Driving onto it with a truck tire... etc.).

          Mold Use:
          Mold Setup:
          • When planning, remember to add 1" - 2" to each side of the sink to your measurements, to account for the concrete thickness on the sides of the finished sink.
          • Apply 3-5 coats of a Mold Release Wax to the mold, lightly buffing between coats once it hazes.
          • Apply small amounts of silicone to the Mold's bottom, and set in place in your form. Allow silicone to dry.
          • Screws can be used to secure the Mold if necessary. Using screws of the appropriate length, screw through the bottom of the form, up into the bottom of the Sink Mold.
          • Run a smooth silicone bead around perimeter of the Sink Mold, where it meets the form base (using a tool such as our Caulking Ball Tool makes this process very clean and easy). 
          • 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 Mold.
            • Wetcast: Oatmeal consistency concrete is placed in form and around the Mold and vibrated. A simple box should be built around the Sink Mold, to contain the concrete during this process.
            • Hand Packed: A drier concrete mix is hand packed into the form and around 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.
            • Most Molds can be pushed out of the concrete by removing the drain piece, and pushing the Mold out through the drain slot.
          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.
