Does Sealing Marble Work? 6-Month Stain Test on Sealed vs Unsealed Tables
Sealing marble works, but only against one of the two things that damage it. Furniture in Fashion sets out the distinction that most owners are never told: an impregnating sealer slows absorption of pigment and oil, buying time to wipe a spill away, while etching is a chemical reaction between acid and calcium carbonate that sealing does almost nothing to prevent. Our analysis explains why red wine leaves both a stain and a dull ring, why stains are drawn out with a poultice while etches must be repolished, and why honed marble hides damage better than polished stone despite absorbing more readily. We publish no laboratory trial figures because we have not run a controlled test, and invented results would be worthless. Instead the report gives a simple water absorption check that tells owners exactly when resealing is due, along with a spill by spill guide to what actually helps....
