Blue Lagoon Quartzite is a natural stone material, and while it is durable overall, 2cm thick floor tiles can be more susceptible to chipping or cracking compared to thicker tiles. It is important to handle and install them carefully to minimize the risk of damage. Additionally, using appropriate sealants and cleaning products can help maintain and protect the tiles over time. Ultimately, while they may be slightly more fragile than thicker tiles, proper care and maintenance can help ensure their longevity and durability.
