How to use broken mirror pieces as tiles

A broken mirror doesn't have to bring seven years of bad luck. It can bring many years of enjoyment if you use the broken mirror pieces as tiles to make a beautiful mosaic for your home. The possibilities are limited only by your imagination. Small collections of pieces make a beautiful picture or mirror frame. Large collections create a stunning table top, tray or even a kitchen back splash. Add interest to your project -- and get extra mileage from your materials -- by combining the mirror pieces with shards of pottery, ceramic or stoneware.

Score the mosaic surface, if possible. Use a craft knife to create a small crosshatch pattern in order to give it "teeth" to help the adhesive stick. Very rigid surfaces like wood, medium-density fiberboard (MDF) and thick chipboard work well.

Lay out your design by placing the mirror pieces on the surface you're going to mosaic. Leave 1/8 to 1/4 inch of space between each piece for grout.

Attach the mirror pieces to the surface with adhesive. Apply to the back of a piece, press into place, and then remove immediately and allow to dry for a few minutes -- if your surface is smooth and you were not able to score it. Replace the piece when the adhesive is tacky. Press into place.

Adhere remaining pieces. Make sure each one sits flat and as flush as possible with the other pieces.

Allow your project to dry for 12 to 24 hours, or according to the adhesive manufacturer's recommendations for cure time.

Mix grout, if you purchased the powdered mix, according to the manufacturer's instructions.

Scoop a small amount of grout with the spatula and apply it to the mosaic. Push the grout between each piece and scrape the surface to smooth it. Use small amounts at a time, and try to fill the gaps completely, so that there are no air bubbles.

Wipe grout off the mirror pieces with the damp cloth as the grout begins to dry. Work with a light touch to remove most of the haze. Allow your project to dry for 24 hours at room temperature.

Buff your mosaic with a dry cloth to remove remaining grout residue, and polish the mirror pieces.


Dye the grout any colour you choose by mixing in acrylic paint. Use just enough to achieve the colour you desire. Allow extra drying time. Use a concrete grout if your mosaic will be kept outside.


Broken mirror pieces can splinter -- wear safety gloves and glasses.
