Countertop Sealing in Park Ridge, IL
Natural stone is porous. A good impregnating sealer slows down how fast oil, wine, coffee and water soak in, so you have time to wipe spills before they stain. We deep clean the countertop, let it dry, and apply a penetrating sealer chosen for your stone.
How do I know if my stone countertop needs sealing?
Put a few drops of water on the countertop and wait a few minutes. If the stone darkens, the water is soaking in and the countertop needs sealing. If it beads up, the sealer is still working. Sealing helps prevent stains but does not stop etching on marble. Send us photos for a quote.
