How to Make a Sea Glass Mosaic

Just as you can make a mosaic out of glass, ceramics, and clay pieces, you can also make a mosaic from sea glass. Sea glass, however, is a bit heavy, so you want to be sure to make a sea glass mosaic on something sturdy like wood.

You can use a sturdy wood tray or just buy a piece of wood in a specific size and shape. You can also search thrift stores or furniture stores for wood tables with a lip around the edges. With these types of tables, you can create a sea glass mosaic on top.

In the steps below, you’ll see how to make a sea glass mosaic on a wood tray.

How to Make a Sea Glass Mosaic

Things You’ll Need

  • Wood base
  • E-6000 Industrial Strength Adhesive
  • Non-sanded grout
  • Sponge
  • Grout sealer
  • Sea glass

Sea Glass and E-6000

 

Step One

Decide on a pattern. You can arrange sea glass on top of the wood base. You can also draw a scene or picture first and then arrange the sea glass accordingly. Be sure to leave at least a 1/8 inch space between the sea glass shards for grout.

Step Two

Begin gluing sea glass to wood with E-6000 Industrial Strength Adhesive. Squeeze a little glue out from the tube and use a Q-tip to smear a little glue on the back of sea glass. E-6000 dries quickly, so just squeeze out a little at a time.

Step Three

Wait at least 24 hours before grouting. Then check each sea glass shard to be sure you didn’t miss any during the glueing process.

 

Step Four

Mix non-sanded grout according to package directions and use a knife or spatula to spread the grout as evenly as possible over the sea glass.

Grout comes in different colors. For this project, I used non-sanded white grout from Home Depot. I also used blue painter’s tape to protect the edges of the wood tray.

Step Five

Wait 30 minutes. Then using a damp sponge start wipping away the excess grout.  Keep rinsing the sponge and wiping away grout until the sea glass is clean.

Read the directions on the package of grout as waiting times may vary.
