DIY Glass Mosaic Instructions

CAUTION SHARP GLASS

Thank you for your purchase. If you have any questions please contact me below. Please be careful as glass is sharp edged. Please wear gloves and use tweezers when handling. This kit is intended for those 8+ years and older with adult supervision.

Please follow the instructions below for your DIY mosaic board:

  1. Sketch your design (if you'd like one) on the 1/8" backing board using pencil so it does not show through glass or grout
  2. Using tweezers lay the glass pieces on the base without adhesive to ensure proper fit.
  3. Leave small gaps between pieces for grout.
  4. Apply adhesive to the back of each glass piece or directly to the base in section, pressing each piece firmly into place.
  5. Let the adhesive dry completely for 24 hours

Grout Application

  1. Add grout to a container and add water very slowly using the stirring stick to achieve a brownie/cake like batter.
  2. Spread grout over the mosaic, using the other stirring stick carefully pushing it into the gaps between pieces, use it like a spatula.
  3. Add water to inflatable sponge and wipe away excess grout with a damp sponge.
  4. After the grout has set (usually 15–30 minutes), clean the surface of the glass with a sponge or cloth to remove grout haze.
  5. Let the grout cure fully and after give another wipe with a damp and then dry cloth. 

It is important not to let any grout dry and harden on the glass itself in chunks but if it does not come off in the final clean up stages you can take a razor blade or exacto knife and scrape it off.
