1. Make sure the grain direction of the stainless steel is correct. If not, the metal mosaic may show uneven light reflection and appearance. 2. The installation surface must be clean, dry, and level to ensure proper adhesion and long-lasting results. 3. Apply the adhesive using a straightedge trowel. It's recommended to work in sections no larger than 15 square feet at a time for better control and even coverage. 4. After applying the adhesive, use a notched trowel to spread it evenly. Press the mosaic firmly into place so that the notches make full contact with the surface, ensuring consistent adhesive thickness. 5. Allow the metal mosaic to set and bond to the surface for at least 24 hours before proceeding to the next step. 6. Once fully adhered, apply a professional-grade caulk along the seams for sealing and durability. Let it cure for about 15 minutes or as instructed by the manufacturer. 7. Clean the surface gently to remove any excess adhesive or stains. Use a soft cloth and mild cleaning solution to avoid damaging the finish. 8. Finally, apply a thin, even coat of clear protective varnish over the entire surface. This will help preserve the shine and protect against scratches. You can find this type of varnish at most hardware stores or home improvement centers.
