Concrete Sink Mold, Farm 30" Sloped

Product Detail:

'Farm' style Sink Mold for concrete sink fabrication.

Unique sloped front design.

Large style drain for kitchen/disposer size drains. Drain is offset on one end.

Create a seamless integral concrete sink and counter top.

Reusable- Durable fiberglass construction allows reusing the mold time and time again. (Unlimited with proper care)

Easily pays for itself with just one use.

Sink molds have nice clean edges and surfaces.

Includes one disposable foam drain-hole knockout piece. Additional foam drain pieces available separately.

Each mold comes with handles on the inside of the mold to aid in pulling the mold out of the concrete.

Product Specifications:

Sink Mold Measurements: 30"L x 14"W (At Top of Finished Sink, 10" Wide at Bottom) x 10"D**. Drain is centered 10.5" from the left side (when the finished concrete sink is looked at from above).

**NOTE: Depth can be adjusted by trimming/sanding down the fiberglass mold to your desired size.

Remember to add 1" - 2" to each side to your measurements to account for the concrete sides of the sink.

Proper slope (5 degree draft or greater) on sides ensures proper draining and mold removal from concrete.

Mold Setup:

NOTE: Some of the longer sink molds will flex inwards when concrete is poured around them. To prevent this, place a few boards across the inside of the mold as an internal brace, and then place the mold in your form and silicone in place.

Apply a few coats of a strong wax, such as a carnauba based wax, the the mold prior to pouring concrete. We also sell a release agent that is safe for fiberglass, and does not leave an oily residue on the finished concrete.

Molds are designed to simply be siliconed in place, and concrete packed around them, or a simple form built up around the mold to hold the concrete in place.

Mold Removal:

WAX and RELEASE AGENT!! See video below for an example of mold usage. Using wax and a release prior to pouring concrete will usually will allow the mold to just be pulled out using the handles.

Use of compressed air between sink mold and concrete will help pop the mold out. In some cases, adding cold water and ice to the inside of the mold for 10 minutes will shrink the mold just enough that removal is easier.

In extremely difficult to remove cases, the mold can be pushed out of the concrete through the hole made for the drain.

Mold Care:

Clean with a sponge after each use. Any damage can be repaired using epoxy or gelcoat, and sand smooth when dry.

Shipping Information:

Usually ships within 2 business.

Concrete Sink Mold, Rectangle 17"

Product Detail:

The '17" Rectangle' Sink Mold for concrete sink fabrication.

This rectangle shaped sink Mold has distinct angle lines that run from each corner, toward the drain in the center.

Small style drain for bathroom/lavatory size drains.

Create a seamless integral concrete sink and counter top.

Dura-BLU fiberglass Molds are reusable indefinitely with proper care.

Dura-BLU molds have a highly polished Industrial Gelcoat finish.

Dura-BLU Molds are made using the strongest commercial-grade resin, NOT out of GP (General Purpose fiberglass resin).

Each Dura-BLU Mold has an Internal Flange:

• Inner Flange further strengthens and braces the Mold.
  
• Creates a platform to screw into; securing the Mold to the form.
  
• Allows clamps to be used to lift stuck Molds out of cured concrete.
  
  

Each Mold comes with one disposable foam drain hole knockout. Additional Foam Knockouts available here. Reusable Rubber Faucet Knockouts (Large size) can also be used for drain holes.



Product Specifications:

Sink Mold Measurements: 17" Long x 13" Wide x 8" Deep* (8.25" Depth including drain flange).

• *Depth can be adjusted by trimming/sanding down the Mold to your desired depth, but you may lose the Internal Flange that is in the Dura-BLU Molds if you trim very much.
  
• Sides to Dura-BLU Molds have at least a 5° slope to ensure Mold removal from concrete.
  

Mold Setup:
• When planning, remember to add 1" - 2" to each side to your measurements to account for the concrete thickness for the sides of the finished sink.
  
• Apply 2-3 coats of a Mold Release Wax (sold separately).
  
• Apply small amounts of silicone to the Mold's rim, 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 Internal Flange of the Sink Mold.
  
• Run a smooth silicone bead around perimeter of the Sink Mold, where it meets the form base. Silicone Disposable Foam Drain Knockout (supplied with Mold), or Reusable Rubber Knockout, on to Mold. Allow silicone to dry.
  
• Apply a thin coat of Fiberglass Safe Form Release (sold separately) to the Mold just prior to casting the concrete piece.
  
• Various methods can be used to cast the concrete piece:
• 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.
  
• More information available on our Fabrication Tutorials Page.

Any voids in the concrete can be filled using a cement slurry. Add Cenospheres to portland cement to reduce shrinkage and make filling voids easier.

Mold Removal:

If Mold Release Wax and Liquid Release were used prior to casting the concrete, most Molds will usually pull out of the concrete with little effort.

If the mold is difficult to remove:

• Adding cold water and ice to the inside of the mold for 10 minutes will shrink the mold just enough that removal is easier.
  
• Compressed air shot around the Mold rim will break the suction holding the Mold in the concrete.
  
• Using a few blocks of foam against the concrete, place a 2x4 across the Mold, and pry the Mold out using some large C-clamps, or wood working clamps.
  
• Most Molds can be pushed out of the concrete by removing the drain plug, and pushing the Mold out through the drain hole.
  

Warranty and Mold Care:

Each Dura-BLU mold has a Lifetime Guarantee against defect. This Guarantee does not cover misuse of the Molds (Dropping the Mold, Prying the Mold out using a screwdriver... etc.).

Liability Policy: 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.

Clean Mold with a sponge after each use. Waxing and buffing the Mold after use is recommended to maintain the Mold in top condition.

Any damage can be repaired using 2-Part epoxy (Available for a few dollars at any hardware store- comes in a double syringe). Mix the epoxy, apply to the damaged area, and sand smooth when dry. Wet sanding the Mold will return the damaged area to a high gloss if desired.
