Marble and other calcite based stone such as limestone and travertine are prone to acid etching. Marble is immediately 'etched' (eaten / corroded) by any acidic material on contact - including lemon juice, cola, wine and champagne. In any case, acidic substances should be cleaned up as soon as possible.
To preserve its looks, breathe-ability and slip resistance, it is important for marble to be sealed with a high quality, high penetration Impregnating sealer. Impregnating sealers are suitable for all marble surfaces, indoors and out, from kitchen counter tops to marble floor tiles or wall cladding.
