How do I properly apply peel and stick over tile for a seamless and durable finish?

To properly apply peel and stick tiles over existing tile for a seamless and durable finish, first clean the tile surface thoroughly to remove any dirt or debris. Next, measure and cut the peel and stick tiles to fit the space, ensuring a precise fit. Remove the backing and carefully place the tiles onto the tile surface, pressing firmly to ensure they adhere properly. Use a roller to further secure the tiles in place and ensure a seamless finish. Finally, seal the edges with a silicone caulk to prevent water seepage and enhance durability.
