Sink molds have nice clean edges and surfaces.

Product Specifications:

Sink Mold Measurements: Inner- 16.75"L x 16.75"W x 7.5"D**. Outer- 20"L x 20"W x 9"D**.

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

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

Use of wax and a release agent on the mold prior to pouring concrete will make removal easier.

Mold Setup:

Apply a few coats of a strong wax, such as a carnauba based wax, the the molds 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.

This two part mold is designed to simply be siliconed in place. Silicone the inner bowl to a form (melamine, glass, etc.). Place outer Vessel Mold over the inner mold, and silicone the outer mold in place. Pour concrete through hole in the top of the outer shell, vibrating to remove air bubbles as you go. When concrete has cured, remove any cement that has seeped under the outer shell by lightly sanding off with fine sandpaper.

Mold Removal:

WAX and RELEASE AGENT!! Using wax and a release prior to pouring concrete will usually will allow the mold to just be pulled out using the handles.

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.

Using compressed air through the drain hole, or around the sink edges is a very quick and painless way to release the mold (be careful as a high PSI air stream can damage freshly poured concrete).

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.
