Mosaic Stepping Stones
Mosaic Stepping Stone Molds are reusable and made from ABS plastic for long life. The molds come with rounded corners and a slight taper to make it easier to remove the stepping stones after the concrete hardens. We use thinset mortar mixed with small pea gravel (2:1) for stepping stones, but many people use ordinary concrete. Both are available at the building material store. Stepping stones are perhaps the easiest mosaic project for children and beginners. You can use materials of different thickness because you are pressing the pieces into wet concrete.

Using Stepping Stone Molds for Mosaic Art
Tile of different thickness can be used in a stepping stone mold because you are pressing the materials into wet concrete instead of gluing them to a flat surface. You can also use a wide range of hard materials other than tile: toy glass marbles, glass gems, gemstones, quartz crystals, beach glass, found stones, glass figurines, etc. Ceramic tile and unpolished marble can be used as well, but keep in mind that these materials are porous and susceptible to freeze damage. (Glass tile is nonporous and frost proof, so it is preferred for outdoors.) We seal finished mosaics with a grout sealer or concrete sealer for longer life, and you can also bring stepping stones indoors for the winter months to avoid harsh freezes.
Old souviners of glass and porcelain can give your stepping stone personality and charm, but avoid plastic because it is degraded by the sun's ultraviolet radiation. No matter what materials you use, you should always take care not to create a slip hazard or leave sharp edges exposed. That includes not placing glass or ceramic objects in positions where they can be easily broken off.
Tip: If your mosaic stepping stone is ever damaged in such a way that a shard piece is sticking out, you can take a piece of rock and file the rough edge down by gently but firmly rubbing the rock on the rough edge (wear gloves). A marble file is also useful for this type of repair work.
- ABS plastic for long life.
- Deep enough to produce stepping stones 1.5+ inches thick.
- Rounded corners and tapered edges for easy removal of hardened stones.
Petroleum jelly such as the Vaseline brand or non-stick cooking spray should be used to lubricate the mold prior to each use. This ensures easy removal of the stepping stone once the concrete has hardened. If you are wanting to make an elaborate design from ordinary flat tile, then you can stick a piece of contact paper in the bottom of the stepping stone mold with the sticky side up. Press your tile upside down onto the sticky contact paper. When all the tile is positioned, pour concrete on top of that and fill the mold to the top surface. Leave the stone in the mold for 24+ hours before removing to allow the concrete to harden.
