Sealing Natural Stone

Quartzites

For a quartzite product, it is recommended that it be sealed to extend its longevity. Natural stone may absorb moisture during fabrication and from installation materials. Therefore, it is recommended that sealing should be done after the stone has fully dried to ensure proper sealer absorption, and prior to consumer use. Drying time will vary depending on the stone, as well as the temperature and humidity level.

Quartzite has a more open structure and therefore needs a sealer that is designed to penetrate properly to ensure that the stone is sealed. After sealing, allow it to cure completely. Arizona Tile suggests using 3-5 coats of solvent-based impregnating sealer for the initial sealing and applying 1 coat of sealer every 6 months moving forward. It’s also recommended to seal all cut edges, onsite at the time of installation. This will help to minimize water and oils from penetrating into the stone around sinks, faucet holes, ovens and any seams.
