Granite is one of the most popular choices for kitchen and bathroom countertops—and for good reason. It's durable, beautiful, and timeless. But like any natural stone, granite needs a little care to keep it looking its best. One of the most important steps in maintaining granite countertops is sealing them.
In this post, we’ll walk you through the basics of sealing granite, why it’s so important (especially for countertops that get regular use), and how MGL Granite can help.
Why Does Granite Need to Be Sealed?
Granite is a natural stone with a porous surface. That means that if it's left unsealed, liquids like water, oil, wine, or juice can seep into the stone, causing stains or even long-term damage. Bacteria can also find their way into those tiny pores, which isn’t something you want on your food prep surfaces.
Sealing your granite countertops helps create a protective barrier that:
- Repels moisture and spills
- Prevents staining
- Makes cleaning easier
- Extends the life and beauty of your countertops
How Often Should You Seal Granite?
It depends on the type of granite, how much use your countertops get, and the type of sealer used. Some granite varieties are denser and require sealing less often, while others are more porous and need more frequent attention.
As a general rule:
- Seal high-use kitchen countertops once a year.
- For less frequently used areas (like guest bathrooms), every 2–3 years may be enough.
Pro Tip: Not sure if it's time to reseal? Drip a few drops of water on the surface. If it beads up, you're good. If the water soaks in, it's time to reseal.
How to Seal Granite Countertops: Step-by-Step
1. Clean the Surface Thoroughly: Wipe down your granite with a gentle stone cleaner or warm soapy water. Remove all residue and let it dry completely before sealing.
2. Choose the Right Sealer: Use a granite-specific penetrating (or impregnating) sealer that soaks into the stone to provide long-lasting protection.
3. Apply the Sealer: Follow the instructions on the label. Typically, you'll a
pply the sealer evenly with a clean cloth or applicator pad.
Let it absorb for about 15–20 minutes.
Wipe off any excess with a clean, dry cloth
4. Let It Cure: Most sealers cure within 24 hours. During this time, avoid using the surface or getting it wet.
