can you use grout to give it that finished look

Thank you for your interest in our Palisade Carrara Marble PVC Interlocking Wall Tiles! Our tiles are meant to give a faux grout look without needing to use grout in your application. Grout can be used if you would prefer, we would recommend using an non-sanded or sandless grout to ensure not to scratch the surface of your panels. If you have any additional questions please feel free to reach out to us here at 800.434.3750. Thank you!
