Sealing Granite: Why, When, and How to Do It Right

Granite countertops are a timeless and luxurious addition to any kitchen or bathroom. While they are known for their durability, they still require proper care to maintain their beauty and longevity. One crucial aspect of granite maintenance is sealing. But why is sealing necessary, how often should it be done, and what’s the right way to do it? Let’s dive in!

Why Does Granite Need to Be Sealed?

Granite is a natural stone that, despite its hardness, is porous. This means that liquids, oils, and stains can seep into the surface if left unprotected. Sealing granite provides a protective barrier that:

• Prevents Staining – A quality sealer repels spills from coffee, wine, oil, and other common kitchen substances.

• Reduces Bacteria Growth – Sealed granite is less likely to harbor bacteria, making it a safer surface for food prep.

• Enhances Longevity – Regular sealing helps maintain the stone’s finish and prevents long-term damage.

When Should You Seal Your Granite?

The frequency of sealing depends on the type of granite and its level of use. Here’s a general guide:

• Newly Installed Granite – Many countertops come pre-sealed, but it’s best to test and reseal if needed.

• Every 6-12 Months – High-traffic kitchen counters benefit from annual sealing to stay protected.

• Every 1-3 Years – Bathroom vanities or surfaces with less use may only need sealing every few years.

How to Test If Your Granite Needs Sealing

A simple water test can determine if your granite needs a fresh seal:

1. Pour a few drops of water on the countertop.

2. Wait 15-20 minutes.

3. If the water beads up, your seal is still intact. If it absorbs into the stone, it’s time to reseal.

How to Seal Granite Like A Pro

Sealing granite is a straightforward process that you can do yourself:

1. Choose the Right Sealer – Look for a high-quality, penetrating sealer designed for natural stone.

2. Clean the Surface – Use a mild, pH-balanced cleaner to remove dirt and debris. Let it dry completely.

3. Apply the Sealer – Using a clean cloth or sponge, evenly spread the sealer over the surface.

4. Let It Absorb – Allow the sealer to soak into the stone for the time recommended on the product label (usually 10-15 minutes).

5. Wipe Off Excess – Remove any remaining sealer with a dry cloth to prevent streaking or residue buildup.

6. Let It Cure – Avoid heavy use or moisture exposure for at least 24 hours to allow the sealer to fully cure.
