Concrete Sink Mold SDP-56 Trough Design (65" x 12")
- 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-56 - 65" Trough Sink Mold Measurements:
- 65" Trough Sink Mold for concrete sink fabrication.
- 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.
Specificaitons- Concrete Sink Mold SDP-56 Trough Design (65" x 12"):
- 6" Depth: 65" x 12" x 5.5"
- 3" Depth: 64" x 11.5" x 3"
- *Depth can be adjusted when we make the molds upon request. If you need a 2" deep mold, no problem- but keep in mind the length and width will decrease some as well when making a shallower mold. Some additional time and cost will incur.
- Sides of molds have at least a 5? slope to ensure Mold removal from concrete
Mold Use:
- Watch videos of Mold Setup, Casting, and De-Molding/Removal on our .
- A basic Sink Mold Instruction sheet is .
- 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 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 to the Mold just prior to casting the concrete piece.
Concrete Casting:
- Various methods can be used to cast the concrete piece. View our 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 .
- Mix your own slurry by mixing Portland cement, , and water (or water/mix).
