Flagstone/sandstone after 10 years, a few of which were saltwater pool years with no sealer applied. This pool is approximately 10 years old. It was a salt pool, but hasn't been for 5 years. Notice the mortar is higher than the eroded stone. No one told the homeowners to seal the stone.
Whether I seal, or you or someone else, it isn’t snake oil. Gotta seal it.
