How to Make Glass Pavers

Coat the inside of a paver mold with petroleum jelly. Apply a thin coat that covers the entire interior surface of the mold, otherwise the concrete may stick.

Cut a piece of self-adhesive shelf paper so it is the same shape but slightly smaller than the paver mold. The shelf paper must sit flush against the mold's bottom when placed inside the mold. Cut a piece of plain paper the same size as the shelf paper.

Lay the plain paper on your work surface. Arrange glass mosaic tiles on top the plain paper. Rearrange the tiles on the plain paper as needed to create the desired design, shape and size for one glass paver.

Peel the backing off the self-adhesive shelf paper. Lay the sticky side of the shelf paper over the top of the mosaic tiles, and press the shelf paper down so all the tiles adhere to the shelf paper.

Flip the shelf paper over carefully. Lay the shelf paper inside the prepared mold so that the back of the tiles face upward.

Prepare dry mortar mix in a container as directed in its package's instructions. Most mortar mixes require adding water until the mortar is the consistency of thick oatmeal.

Pour the mortar into the paver mold, covering the glass mosaic tiles with 1-inch deep mortar. Allow the mortar to set up for 20 to 30 minutes.

Prepare dry concrete mix in a container by following its package instructions. Pour the prepared concrete into the paver mold, filling it half way. Tap the sides of the mold to settle the concrete so it contains no air bubbles. Finish filling the mold with the concrete, and then tap the mold's sides. Allow the cement and mortar to set and harden for three days.

Turn the mold upside down on a soft surface, such as your lawn. Tap the mold to dislodge the paver.

Peel the shelf paper off the top of the paver, revealing the glass tiles. Wipe remaining adhesive from the tiles with a cloth dampened with rubbing alcohol before placing the paver in a garden.
