Stone Master Molds Cliffstone Molds for Concrete

Discover endless design possibilities with this modern and adaptable dry stack stone mold profile that elegantly enhances a range of contemporary styles through its unique textural elements.

Cliffstone is a semi-jagged, rough-cut dry stack stone mold designed for a tight fit in lengths of 4″ to 17″ and widths of 1.5″ to 5.5″. The finished product/stone is approximately 1-1.75" thick.

In addition, each mold makes approximately 2.4 square feet if dry stacked and 2.9 square feet with a grout joint.

Our molds require NO release agent. Save money, time, and clean up, as well as easy, clean release of face color pigments, unlike plastic molds, urethane molds, and silicone molds.  Available in 5 unique variations, with no stone repeats.  More versions available upon request.

Made in the USA, both materials and labor.

Manufactured Stone Basic Mixing Procedures Using A Pre-bagged Concrete Mix for your Dry Stack Stone Molds:

This is one suggestion for mixing the concrete for the dry stack stone molds in Cliffstone. 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.

Additionally, 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 Cliffstone molds for approximately 24 hours at the minimum of 70 degrees Fahrenheit before demolding. Higher humidity is desired. 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.
