- 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.
- SDP-47 Vessel Box Sink Mold Measurements:
- Length: 15" (Across)
- Width: 15" (Front-To-Back)
- Depth: 4" (At Edge)
- Inside Depth: 2 1/4" (Inside finished sink)
- Sides have at least a 5° slope to ensure Mold removal from concrete
- The 'Vessel Box' Sink Mold for concrete sink fabrication.
- The Vessel Box Mold creates a small square vessel sink, with four distinct angular lines in the bottom of the sink, sloping into the drain.
- A unique single part mold- Just fill this mold up with concrete, and trowel the bottom of the sink flat. When cured, flip over and pop out the concrete sink.
- Vessel Molds can easily turn leftover concrete into revenue earning concrete sinks.
- Small style drain for bathroom lavatory size drains. This Sink Mold comes with a built in drain hole.
- Create a seamless integral concrete sink and counter top, or form around to create a vessel sink.
- 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.).
- 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.
- Watch videos of Mold Setup, Casting, and De-Molding/Removal on our YouTube Video Page.
- A basic Sink Mold Instruction sheet is available here.
- Optional- Rubber molds don't 'need' to be waxed, but it can help to make removal easier. To wax the mold, apply 2-3 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.
- 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.
- 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.
