Stone Master Molds EZ Stack Corner Molds for Concrete

EZ Stack is a stone veneer stacked stone corner mold for concrete that has a clean, contemporary look and is a favorite among designers and architects.  For quick and easy installation, EZ Stack stone comes in 3 widths of 4.5", 3", 1.5". The finished product/stone is approximately 1-1.75" thick.

Additionally, each mold makes approximately 1.5 linear feet dry stacked and 1.75 linear feet with a grout joint. EZ Stack corner molds for concrete are designed to complement the matching EZ Stack flat mold.

What's more, our corner molds are available in 3 unique version, with no stone repeats.  Additional versions available upon request.

A corner plug can be used (sold separately) for 1-step corners, or you can create your own from melamine, plywood, etc. 1-step corners allow you to pour the corners in one step. Pour the long, horizontal end first, place the plug on the mold, then fill the open, short end and lightly vibrate.

Our molds require NO release agent. This will save you money, time, and clean up, as well as easy, clean release of face color pigments, unlike plastic molds, urethane molds, and silicone molds.

Made in the USA, both materials and labor.

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

This is one suggestion for mixing the concrete for the EZ Stack corner 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 EZ Stack corner 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.
