For optimal installation, apply a special natural stone adhesive to a clean, dry surface. Position the mosaic tiles, respecting the grout lines to ensure perfect alignment. We offer adhesives and grouts specifically designed to guarantee a durable and harmonious installation. Once the installation is complete, it is advisable to apply a water-repellent treatment to protect the travertine from stains and moisture. This treatment should be renewed every 8 to 10 years to maintain the appearance and durability of the material. For installation in a shower, it should be renewed every 3 to 5 years
