To install your First-Choice light travertine tiles, you will need tile adhesive, a notched trowel, tile spacers, and stone-colored grout. Begin by applying the adhesive to the surface, taking care to remove any excess afterward. Apply adhesive to your travertine tile to ensure better adhesion. For laying travertine in an opus pattern, position your travertine tiles according to the diagram provided in the photos on this product page. As you lay the tiles, we recommend placing spacers between each tile to facilitate grout application. Please note that we offer both the adhesive and the grout. To allow for cuts or other unforeseen circumstances, Ligerio advises you to purchase 10% more than the initial quantity you planned
