Choose a grout color that contrasts with the mosaic tiles to highlight the design; color should complement, not match the tiles
Seal grout for pieces in kitchens, bathrooms, or outdoors to protect against mold, mildew, moisture, and stains
For outdoor projects or those exposed to water, use waterproof acrylic sealants; seal porous surfaces like timber or MDF to prevent water damage
Use narrow grout gaps for a cleaner, more realistic appearance; wide gaps can detract from the mosaic's visual impact
Ensure no adhesive is on the tile faces and clean the surface thoroughly before grouting
When mixing and applying grout, wear gloves and avoid inhaling the powder; grout can be irritating to the skin and lungs
Mix grout to the consistency of thick oatmeal for easy application; re-stir and let stand if too watery
Grouting secures the mosaic pieces, providing durability and a clean finish; it also protects against dirt and moisture
Choose from sanded, un-sanded, or epoxy grout based on tile type; sanded grout is common for ceramic and stone, un-sanded for polished surfaces, and epoxy for water-free applications
After grouting, polish off any haze and ensure grout is flush with or slightly lower than the surrounding tiles for a neat finish
