DIY Mosaic Coaster Supplies

Here are your step-by-step instructions on how to make glass mosaic coasters for yourself, for a loved one, or with your children.

diy mosaic coaster step 1

Glue your glass mosaic tile to your ceramic tiles

1.  Lay out your plastic drop cloth and unpack your ceramic tiles, glue and mosaic glass tiles.

2.  Start your first coaster by adding 1 dot of glue directly to 1 mosaic glass tile (or add the dot of glue directly to ceramic tile) and place each glass piece to your ceramic tile, starting in one corner and making a row on one edge of your ceramic tile. Ensure your row is flush to the edge of the ceramic tile and space your glass pieces evenly across (1/2cm or less spacing is optimal). Use your first row of glass pieces as a guide for mosaic’ing the remainder of your coaster. For additional tips on gluing, click here.

3.  Once you have glued your mosaic glass pieces to ALL 4 ceramic tiles, wait at least 2 hours (2-24 hours is recommended) for your glue to cure/bond before you apply grout in Step 2. While you wait for your glass pieces to bond, check the position of your glass pieces because you’ll likely need to move a few back into place (now is the optimal time to fix any issues).

4. Fill your water container ½-way with water and allow your craft sponge to soak. Unpack putty knife and grout.

5.  Using your hand, add a dollop up grout to the top of your coaster, then use your putty knife to spread the grout evenly, pressing into each crevice. Be sure to apply grout to the sides too and scrape off as much excess grout as possible.

6.  Your grout should be slightly drying and becoming hazy after about 30-60 seconds. You do not want the grout to dry completely on top of your glass, therefore you will move onto Step 3 quite quickly.

Grout your DIY mosaic glass coasters

step 3

Sponge off your grout

7. Ring out the water from your sponge very well (no dripping…you do not want to overwater your coaster). Using one side of your sponge, wipe off grout in one section going DOWN (vertically) by wiping from top left corner area toward bottom left corner area. Flip your sponge over to a clean side and repeat the same action in the next grouted section by wiping from top right corner area toward bottom right corner area. Rinse your sponge in your water container and ring it out. Repeat this process, except this time wipe from side to side, ACROSS (horizontally). You may repeat your sponge cleanses and vertical and horizontal wipes only if you have obvious grout that seems caked onto your tiles. 

DON'T WORRY, THE WATER WILL LOOK DIRTY, BUT WHEN YOU RING OUT YOUR SPONGE, YOUR SPONGE WILL BE CLEAN.

8. Once you have light grout residue-haze remaining, clean up the sides and back with your clean, damp sponge.

 

9. Wait 3+ hours before you move on to Step 4. While you wait, dispose of your dirty water (it is recommended you dispose outside in dirt or rocks rather than your sink). Rinse your sponge with clean water. 

Clean off the surface

10. Once you have waited until all your grout is completely dry, use your slightly damp, clean grout-sponge to clean the surface of your coasters. Your excess, dusty grout should be easy to remove with your sponge.

Spot check

11. At this point, a few glass pieces may need a little extra TLC. Lightly dab your cloth in a little clean water and polish up glass pieces that need extra cleaning. em ipsum dolor sit amet, consectetur adipiscing elit. Ut elit tellus, luctus nec ullamcorper mattis, pulvinar dapibus leo.

Last step: Rubber bumpers!

12. Adhere 1 rubber bumper to each corner of the underside of every ceramic tile (4 per ceramic tile).
