  • The 30" Farm Sink Mold for concrete sink fabrication.
  • The 30" Farm is a large rectangular shaped farm Sink Mold. This design features tight corners (small radius) and distinct angular lines in the mold that transition into a unique aesthetic design in the bottom of the finished concrete sink.
  • Create a seamless integral concrete sink and counter top, or form around to create a vessel Farm Sink.
  • Each Sink Mold comes with a reusable rubber drain hole knockout.
  • We also have Foam Knockouts available here for easier removal and less stress on the fresh concrete.
  • Oversized, Extra-Deep kitchen drain hardware designed for thicker concrete sinks sold here (up to 1-7/8" thick sinks!)

  • Expressions LTD will not be held liable for any damage, misuse, or collateral damages resulting from use of any of our products. If there is a flaw or defect with a product, we will fix or replace the product.

Mold Use:

Mold Setup:

  • Rubber molds may have a little oil on them when you receive them, from our manufacturing process.  Clean off any oil with a mild cleaner and paper towels.  Once clean, apply Mold Release Wax.  Lots of coats of wax will help get mold out easier!  You may want to lightly sand the mold by hand with 200 or 400 grit sandpaper, to give it a little more surface to 'hold' the wax: To wax the mold, apply 5 coats of 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.
    • Rubber type molds are usually stuck in concrete like an air-suction.  Sliding a very thin plastic putty knife between concrete and mold is usually all it takes to release the air suction on a very stuck mold.

Clean-up and Care of The Concrete Sink Mold SDP-27 Farm (30"x15"x10"):

  • 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.

      Good mold, good customer support

      I've bought many molds through the years from Expressions and they always come through. If there is a question, they answer the phone with answers. What more can you ask for.

      Farm sink

      Good sink as expected..
      shipping costs seem high. even for smaller products bought accessories' elsewhere because of high shipping costs (example mold release wax cost is ~20 and shipping is 18$ :O)
