Create a Beautiful Mosaic Stepping Stone for Your Garden

This week’s project is a continuation on the theme of mosaic stepping stones. Last week I presented a stepping stone made using a garden paver & the direct method of mosaics. This week, I’m using a stepping stone mold, concrete & the indirect method of mosaics. Both methods result in beautiful mosaics, with this method the tiles are embedded into the stepping stone as opposed to being placed on top.

Heart Mosaic Stepping Stone


Materials List

  • Stepping stone mold
  • Cement
  • Tiles & tesserae – I’ve used a selection of venetian glass tiles, iridised glass tiles, malachite cabochons, glass gems & van gogh glass tiles.
  • Tile nipper
  • Contact paper
  • Vaseline
  • Paper towel
  • Pen
  • Scissors
  • Container & spoon for mixing cement
  • Dust mask
  • Chicken wire
  • Grout grout or cement oxide
  • No gluing or grouting is required as this stepping stone is made using the indirect method of mosaics.


  1. Trace an outline of the mold onto the contact paper, trim it to the size of the mould. The contact paper needs to be smooth & free from ceases, it must also fit closely inside the mold.
  2. Prepare your design, cut tiles & place face down on the sticky side of the contact paper. Make sure all the pieces are adhered securely to the contact paper and that you have a gap between each piece for the cement.
  3. Using paper towel, apply a thin coat of vaseline along the inner edges of the empty mold.
  4. Mix cement following the directions on the packet. If you wish to colour your cement you can add a grout colourant or cement oxide. Wear a dust mask while mixing the cement. I’ve used an off white cement & charcoal grout colourant.
  5. Pour the cement slowly and evenly into the mold. Do not move the mold when the cement is drying.
  6. To make the stepping stone more durable you place a piece of chicken wire to the mold half way through pouring the cement.
  7. Tap the sides of the mold for 2 or 3 minutes to release any air bubbles in the cement.
  8. Wait for the cement to harden, this will vary depending upon the type of cement, the cements consistency & weather conditions.
  9. Remove the stone by turning it over & lifting up the edges of the mold.
  10. Peel off the contact paper and clean off any excess cement. You may need a paper towel, sponge or craft knife.
  11. Fill any remaining air holes by mixing a small amount of cement and rubbing it into the holes in a circular motion. If your project gets any marks or you have lines in the cement, sandpaper should be able to smooth them out. When mixing your cement (prior to adding water) it is a good idea to set aside a small amount of dry cement for this purpose, particularly if you’ve added an oxide.
  12. Allow the cement to cure completely
