How to Grout a Glass Backsplash

When selecting tile for your kitchen backsplash, don’t overlook colorful glass tiles. Glass tile is a sleek and modern alternative for those who find traditional tile does not create the lively backdrop they’re aiming for. As with ceramic and clay tile, glass tile requires grouting after you set the tile in place. The grout fills the spaces between the tiles while permanently sealing them to the wall. Make sure that your glass tiles are clean and dry before beginning the project.

    • 1

      Mix unsanded cement grout powder with water according to the manufacturer’s directions. Unsanded grout is crucial to this project. Sanded grout may scratch your glass tiles.

    • 2

      Spread a generous amount of grout on the flat end of a hard float.

    • 3

      Spread the grout in a thick layer across the tile. Hold the float diagonally or at a 45-degree angle to ensure that the grout spreads evenly between each tile. Continue spreading grout until you cover the entire backsplash.

    • 4

      Hold the float either horizontally or vertically against the backsplash. Gently scrape away the excess grout. Let the remaining grout harden for 20 minutes.

    • 5

      Wipe the surface of the tile with a damp sponge. Let the tiles dry.

    • 6

      Polish away any remaining grout haze on your glass tiles, using a soft cloth.
