• 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:
• 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!! 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.
• 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.
