Steps To Make The Mosaic Heart

1. Prime the wooden heart with the white spray paint primer. Let dry. (We chose a 3¼” wooden heart to make this mosaic, but you can easily scale this project up. We’ve seen wooden hearts 4″ across and even 9″ across. Of course, you’ll need more tiles! You can even make a mosaic heart with seashells.)

2. Arrange the tiles to cover the heart. To glue the tiles down, place a dab of silicone on the back of each tile and press the tile into place. Don’t worry if some glue squishes out from under the tile, the grout will cover it up.

If you don’t know how to cut thrift store china into tiles and you’d like to learn, we have a how-to that includes that. Click here to see how easy it is to cut china into mosaic tiles. If you don’t want to cut your own tiles from china, you can buy them online!

We like to make a border first using the mini tiles. Then fill in the center with broken china tiles. We added a sweet resin rose to our mosaic and placed it in the center of the heart. Let the glue dry completely before you move on to grouting. It should take about 30 minutes to dry.

3. Put on your gloves, it’s time to mix the grout! To do this, place about a tablespoon of water in the mixing cup. Dry off the measuring spoon and use it to add 3 tablespoons of dry grout to the mixing cup. (Of course, read the directions on the grout you buy. It may require a different ratio of water to grout.) Mix the grout with the putty knife. The goal is to make the grout the texture of natural peanut butter––not dry and crumby and not runny. Add water as needed to get the right consistency.

4. Once the grout is mixed, you have about 15 minutes to use it. Smear the grout over the mosaic with the putty knife.

Use your gloved finger to make sure grout gets in between and around every tile. Use the edge of the putty knife or a craft stick to push the grout under the edges of the rose, but avoid getting any grout in the rose petals.

5. Remove the excess grout from on top of the tiles with a damp sponge. Be careful not to remove the grout from between the tiles. Rinse the sponge in the bucket to clean it as needed.

6. Let the grout set up for 15-20 minutes then buff the surface of the tiles to remove any grout haze. You can use the damp sponge to buff or use a dry paper towel.

7. Let the mosaic dry overnight, then use the sponge paintbrush to paint the mosaic with a coat of grout sealer. Let dry and admire your work!

How fun is that?! It’s a great project for a craft party, too. Set out all kinds of mini tiles, resin roses, and broken china pieces. Or get a pair of tile cutters at your local hardware store and take turns cutting china plates into tiles for the hearts. It’s easier than you think!
