Manufactured Stone Basic Mixing Procedures Using A Pre-bagged Concrete Mix: This is one suggestion for mixing the concrete for manufactured stone. 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. Cure in the 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.

Example of one post topper made with the rubber mold. Using this one mold to create toppers 12 times and continues to withstand the use. Extremely easy to use and very affordable and produces an excellent quality.
