DIY Mosaic Stepping Stones

After making my DIY mosaic flower pots, I have to admit I’m on a mosaic kick! I feel like I’m seeing my world through stained-glass-colored glasses now.

Unlike my prior mosaic project, there’s no need for tile nippers or grout for this craft. All you need is a good mold, the right concrete mix, and some pretty tiles.

Note: Some stores also sell a complete stepping stone kit that comes with pre-printed designs.

Supplies

Safety Tips for Making DIY Stepping Stones

  1. Work in a well-ventilated area, preferably outdoors. This will prevent you from inhaling the stepping stone mix particles.
  2. Always use protective gear when mixing concrete, including a face mask and gloves. You want to avoid skin contact with the concrete mix.
  3. Adult supervision is required for this project. Kids can definitely help with placing the mosaic tiles, but an adult should always supervise this activity.

Step 1: Design your Mosaic Pattern

If you own a Cricut or Silhouette Cameo cutting machine, I highly recommend using it to print and cut your pattern beforehand. It’s a big time-saver!

Otherwise, you can cut out basic shapes in a piece of cardstock paper or use a freehand pattern.

If you’re using a specific design, it’s helpful to trace the shape of your stepping stone mold onto the design. Then, you arrange your tiles beforehand, as shown above.

Step 2: Mix the Concrete and Pour into Mold

Once you have your tiles ready, mix the concrete or stepping stone mix according to the manufacturer’s instructions. Always wear a mask and gloves for this part.

Once the mix reaches a cookie batter consistency, you can pour it into your mold.

Use a putty knife to smooth the surface of the concrete. Then, gently tap the edges of the mold to release any air bubbles.

Step 3: Apply Mosaic Tiles to the Stone

After about 10 minutes, you can begin placing your tiles onto the concrete mix.

It helps to place the paper pattern onto the mold first. Then you can outline the pattern with tiles before placing the main pattern tiles.

Make sure the mosaic pieces are firmly set into the concrete so they won’t fall out later.

Step 4: Polish the Stepping Stone

After 24 hours, polish the mosaic tiles with a wet toothbrush and remove the stone from the mold.

You can continue polishing the stone with a soft cloth and use sandpaper to file any sharp edges.

Now you’re reading to decorate your garden or outdoor patio space with your DIY mosaic art!

Note: Wait 7-10 days before applying pressure to the stone.


5 Tips for Getting the Best Results

Before you begin prepping your materials to create your stone, here are a few tips to keep in mind.

  1. The temperature and humidity may affect drying times for your concrete mix. Ideally, make your stepping stones on a day with lower humidity and moderate temperatures (around 60-70°F).
  2. Add water very gradually when stirring your concrete. A little water goes a long way!
  3. Dab off any excess water on the surface of your mix with a paper towel before applying your design.
  4. Be sure to press the tiles in place gently so the concrete rises slightly between the tiles.
  5. If any tiles do not adhere after the stone has dried, you can always secure them in place with E6000 or mosaic tile adhesive.

Notes

If tiles do not adhere properly after the stone is set, you can reapply them with E6000 or tile adhesive.

You can sand any rough edges of your finished stone with high grit sandpaper or the edge of a screwdriver if necessary.

    1. What a compliment, Paula. Thank you! I think I’m going to buy more of the concrete mix to make a few more. It was a lot easier than I thought it would be.
