Begin installing tiles in the center of the wall, one grid at a time. Finish each grid before moving to the next. Start with the first tile in the corner of the grid and work outward. Set tiles one at a time using a slight twisting motion. Don't slide tiles into place. Insert tile spacers as each tile is set, or leave equal joints between tiles.

Apply a suitable adhesive evenly to the wall using a notched trowel, ensuring sufficient coverage for optimal adhesion. Press the tiles firmly into place, using spacers to maintain consistent spacing between tiles and achieve uniformity in the layout. Finally, grout the tiles once the adhesive has cured.
