All sizes are nominal. ** Sealing is mandatory for crackle glazes. It is recommended that you seal your tile with a penetrating sealer before and after grouting. In addition, it is recommend that you reseal every twelve months or so. The sealer is used to penetrate the fine, hairline fissures in the glaze, preventing dirt and dust from darkening the crackle over time. The sealant makes cleaning and maintenance over time much easier. For regular cleaning we recommend a non- abrasive/ non-acidic, mild and PH neutral cleaner. **
