Sealers cure as a film on your natural stone countertop. Since the material is actually covering the stone, the appearance of the surface may be altered. The sealer will absorb most of the wear on the countertop. Since it is softer than the stone, normal use of the countertop will result in abrasion of the sealer surface and require periodic reapplication to maintain its original luster. A properly applied topical sealer will normally reduce, although not eliminate, the vulnerability of calcareous stones from mildly acidic solutions.
General Precautions: When any surface protection product is used, care must be taken to read and follow the manufacturer's instructions accurately. This will provide the greatest benefit from the application and will guarantee safe handling of the product.
