Concrete Sink Mold SDP-44 ADA Shallow Ramp Slot Drain (17"x14"x3"):
- 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.
- The Shallow Ramp sink Mold has a very low profile design, only 3" deep allowing for meeting ADA requirements in most cases.
- Slot Drain Style drain. Plexiglas piece included with Mold to use for creating the slot drain.
- All drain hardware hidden from sight. Drain kit assemblies are sold separately, available in Stainless Steel or Black ABS Plastic (The 17" Drain Pan size fit the SDP-44 Shallow Ramp Sink Mold).
- Create a seamless integral concrete sink and counter top, or form around to create a vessel sink.
- Each Mold comes with one reusable Plexiglas Slot Drain knockout, with angled ends for easier removal from concrete.
- 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.
- 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.
- 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 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.
- 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.
- 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.
Clean-up and Care of The Concrete Sink Mold SDP-44 ADA Shallow Ramp (17"x14"x3 1/8"):
- 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.
