1. Make sure the grain direction of the stainless steel is correct. If not aligned properly, the metal mosaic may show uneven light refraction and an unprofessional appearance. 2. The surface where you're installing the mosaic should be clean, dry, and level. Any dust or debris can affect adhesion and lead to gaps or lifting over time. 3. Apply the adhesive using a straight-edge trowel. It's recommended to work in sections no larger than 15 square feet at a time to ensure even coverage and proper setting. 4. Once the adhesive is spread, use a notched trowel to comb it out. Press firmly so that the notches make contact with the surface, ensuring a consistent and even layer of adhesive for better bonding. 5. Let the metal mosaic sit and set for at least 24 hours before proceeding. This allows the adhesive to fully cure and ensures a strong bond. 6. After the initial setting, apply a professional-grade caulk around the edges or seams. Allow it to cure for about 15 minutes to create a waterproof seal and enhance durability. 7. Once everything is set, gently clean the surface of the metal mosaic with a soft cloth and mild detergent. Remove any excess adhesive or stains immediately to avoid permanent marks. 8. Finally, apply a thin, even coat of clear protective varnish to the surface. You can find this type of varnish at most hardware stores. This step helps protect the metal from scratches, corrosion, and everyday wear.
