Countertop Sealing in Wheeling, 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.
Signs your countertop needs sealing
- Water darkens the stone instead of beading

- Rings from wine, coffee or juice
- Dark areas around the sink
- It has been years since the last sealing
Our process

- Deep clean Residue and old film are removed so the sealer can penetrate.
- Dry The stone is allowed to dry so moisture is not trapped.
- Apply sealer A penetrating sealer suited to your stone is applied and worked in.
- Remove excess Excess is buffed off so no hazy film is left behind.

Does sealing stop etching on marble?
No. Sealer helps against stains, but acids still react with marble. Etch marks are removed by honing and polishing.
