Begin by selecting a grout color that complements your mosaic design. Some installers prefer a matching grout that creates a seamless look, while others choose contrasting colors to highlight individual tiles and create visual interest. Mix your grout according to manufacturer instructions, achieving a smooth, consistent texture comparable to thick frosting. Work in small sections to prevent the grout from drying before you can clean and shape it properly.
Apply the grout using a rubber float held at a 45-degree angle, pressing firmly to ensure complete coverage between tiles. Move diagonally across the mosaic to avoid dislodging tiles or creating uneven grout lines. Work methodically and deliberately, filling every joint completely while removing excess grout from tile surfaces. After initial application, wait approximately 15-20 minutes for the grout to slightly set before beginning the cleanup process.
Cleaning requires a delicate touch and precise timing. Use a damp sponge to gently wipe the tile surfaces, rotating the sponge frequently to prevent redepositing grout. Rinse your sponge in clean water, wringing it out thoroughly to avoid oversaturating the grout lines. Multiple light passes are more effective than aggressive scrubbing, which can remove fresh grout from between tiles.
After the initial cleaning, allow the grout to cure for the time recommended by the manufacturer. Some projects might require sealing the grout to protect against moisture and staining. Learn strategies for waterproofing and protecting your tile installation to extend the life of your mosaic.
Verify your grouting meets these critical criteria:
