Should a Stone Dining Table Be Sealed?

Some natural stone tables benefit from an impregnating treatment; others absorb very little, already carry a factory application or change appearance under the wrong product. Alex Zheng treats sealing as a documented material decision. The process starts with the full slab and finish, uses a representative test, checks color and residue after cure, and ends with a care record. It never promises protection from acids, scratches, heat or every possible stain.
