What is Marble?
Marble is a different story because it’s much more porous. We recommend using an impregnating sealer, but even then acids such as citrus juice, vinegar, and wine can etch the surface. But that isn’t necessarily bad news–many homeowners enjoy the character that marble countertops take on over time. To reduce the appearance of etching, Weber recommends getting a dull, honed finish rather than a polished finish when buying marble. She also points out that if worn marble countertops become unsightly, maintenance specialists can pull out stains with a poultice and rehone the surface to make it look new again.
Care & Maintenance
Not all granite counter tops require a seal according to the Marble Institute of America but may benefit from a quality sealer product. Most manufacturers place a resin treatment on granite at the factory. The sealant product should last ten to fifteen years and be of an oliophobic (resistant to water and oil based stains) type. Once properly sealed, the stone will be more resistant. Please refer to specific manufacturers instructions.
Clean the surface thoroughly- removes any stains-allow the stone to dry for several hours- pour the sealer on the surface.
Spread the sealer over the counter top with a paper towel, foam brush or rag- allow the sealer to penetrate 5-10 minutes- (if the sealer is completely absorbed in 5 minutes add more) –after 5-10 minutes blot any remaining sealer- buff the stone dry with a clean terry cloth and let dry for 12 hours before use- make sure your work area is well ventilated.
