Do all natural stones need to be sealed?
Yes, we recommend sealing in all cases, there are several types of sealers, the most beneficial is a penetrating sealer. Unless the supplier has a pre-sealed product, in this case follow their recommendations. If the stone is being used in a pond application, you may choose not to seal it. Most sealers are toxic to fish. For more detailed information, please see the Spirit Sealers & Cleaners page in the Links section of this site.
