Product Description:

• The 'Vessel Shallow' Sink Mold for concrete sink fabrication.
• The Vessel Shallow Mold creates a very shallow, modern and sleek concrete vessel sink.  Designed to be used with low-flow faucets to minimize splashing.  The Shallow Vessel concrete sink also works great when placed in a depression in the concrete, to catch any overflow or splashing and funnel it underneath the Shallow Vessel, into the drain.
  
• A unique single part mold- Just fill this mold up with concrete, and trowel the bottom of the sink flat. When cured, flip over and pop out the concrete sink.
• Vessel Molds can easily turn leftover concrete into revenue earning concrete sinks.
• Small style drain for bathroom lavatory size drains.
• Create a seamless integral concrete sink and counter top, or form around to create a vessel sink.
• Dura-BLU fiberglass Molds are reusable indefinitely with proper care.
• Dura-BLU molds have the highest grade Industrial Gelcoat finish.
• Dura-BLU Molds are made using the strongest commercial-grade resin, NOT out of GP (General Purpose fiberglass resin).

Single Part Vessel Mold Setup:

• IMPORTANT! Most customers will want to take a Scotch-Brite pad (or about a 200 grit sandpaper) and lightly buff the Dura-Blu Mold prior to use. This scuffing of the surface will allow the Mold Release Wax to stick onto the Mold better, and help prevent excessive sticking to the concrete when de-molding. Dura-Blu Molds are shipped with a high-gloss gelcoat finish for those who require a mirror-like finish in the concrete sink... but who are usually prepared for a more difficult time removing the mold!
• Apply 2-3 coats of a Mold Release Wax (sold here), lightly buffing between coats once it hazes.
• Apply a thin coat of Fiberglass Safe Form Release (sold here) to the Mold just prior to casting the concrete piece.

Concrete Casting:

• 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.
  
• 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 concrete can be filled using a cement slurry (sold here).
  
• Mix your own slurry by mixing Portland cement, Cenospheres (sold here), and water (or water/Polyplex mix).

Mold Removal:

• 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:
1. Compressed air shot around the Mold rim will break the suction holding the Mold in the concrete.
2. Adding cold water and ice to the inside of the fiberglass mold for 10 minutes will shrink the mold just enough that removal is easier.

Mold Clean-up and Care:

• 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.
• Damage: Any damaged areas (chips, scratches, imperfections, etc.) can be repaired using 2-Part epoxy (available for a few dollars at any hardware store- comes in a double syringe). Mix the epoxy, clean the damaged area and apply the epoxy to the damaged area.  Sand smooth when dry. Wet sanding the Mold will return the damaged area to a high gloss if desired.  Bondo can also be used, although it usually won't stick to the Mold as strong as epoxy will.
