We manufactured our River Rock Stone molds out of hand selected and
modified stones pulled right out of the Mississippi River so that you can
mass-produce top of the line decorative concrete. Everything from the mold to
the rubber we use is manufactures in the USA, so our products are consistently excellent.
River Rock molds are typically used for walls, and might be a tripping hazard if used for tiles. They could however be used for tabletops, or anything else your imagination desires. Most mold models have the option to purchase a set, which will make your final product look much more natural, and less like you "copy-pasted" the same mold over and over again. Every set piece is numbered /1, /2, /3 etc. at the end of the mold number.
The estimated mold life is 2000 castings with proper storage and use. Always use a release agent (we recommend G-1 Release) and store on a flat, surface in a cool, dry location out of direct sunlight. While using the molds outside, throw a tarp over them or keep them out of direct sunlight. UV radiation severely damages the molds.
