Stone Master Molds Mountain Ledge Flat Molds for Concrete

Mountain Ledge stone veneer molds for concrete produce a dry stack, contemporary stone, hand-cut in lengths of 5″ to 20″ and widths of 1.5″ to 5″. The finished product/stone is approximately 1-1.75" thick. Therefore, these molds are ideal for making your own stone veneer for any indoor/outdoor project where stone cladding is needed.

In addition, each stone veneer mold for concrete is approximately 22.75" in length by 20.5" wide by 2" deep and makes approximately 2.11 square feet dry stacked.

What's more, 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.  Additional variations available upon request. Matching Mountain Ledge corner molds are also available.

Made in the USA, both materials and labor.

Manufactured Stone Basic Mixing Procedures Using A Pre-bagged Concrete Mix for your Mountain Ledge Flat Molds:

This is one suggestion for mixing the concrete for the Mountain Ledge flat molds. 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.

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 Mountain Ledge 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.
