Manufactured Stone Basic Mixing Procedures Using A Pre-bagged Concrete Mix for your Water Table - Window Sill Mold:

This is one suggestion for mixing the concrete for this mold.  Of course, there are many other instructions available online, including videos.

BE SURE TO USE A CONCRETE MIX THAT CONTAINS PORTLAND CEMENT. We recommend Sakrete Maximizer, as it has lightweight aggregate, is high strength, and yields more product, but there are many kinds you can use. Follow the manufacturer’s instructions for mixing.

If using pigment, add desired iron oxide pigment to mixer (100% pure, no additives). These can easily be found on Amazon, etc.

In addition, a plasticizer can be added to reduce the amount of water in the mix. Pour into the molds which may already have coloring additives… NO RELEASE AGENT NECESSARY. Vibrate molds to release air bubble.

Finally, cure the concrete in the window sill molds for approximately 24 hours at the minimum of 70 degrees Fahrenheit before demolding. Higher humidity is desired. Furthermore, molds can be covered with a tarp to retain more heat and humidity. Continue to cure demolded stones at 70 degrees or greater until ready.

  1. Happy Bird

    Be sure to add rebar to the mortor or it will snap in two. I added wire to the rebar and used it to aid in attaching to side of building while the mortor set. Stained concrete with concrete stain paint. That way it is always a consistent color. Will add pics when done with project.

  2. Pete the dragon

    This mold is amazing! I have used it about 10times and each one came out perfect! I used a releasing agent the first time because I have plastic molds and you must on those but the second time I didn’t and it worked just as good.

    Made about 200 of them….. like printing money
