How Often Should You Seal Natural Stone?
Sealing your natural stone is one of the best ways to protect it from damage. Whether you have granite countertops, marble vanities, travertine floors, or limestone showers in your St. George home, keeping the surface sealed helps block stains, moisture, and wear. But how often should you seal it?
At Sky’s Stone Care, we recommend sealing most natural stone every 12 to 18 months. This timeline depends on the type of stone, where it’s located, and how often it’s used.
Why sealing matters:
Stone is porous. That means it can absorb liquids like water, oil, coffee, or wine. Once absorbed, those liquids can cause stains, discoloration, or breakdown of the stone surface. Sealing fills in the pores and creates a protective barrier.
St. George conditions can wear down sealer faster:
The dry air, dust, and hard water in Southern Utah can cause sealers to break down faster than in other areas. We’ve seen many homes in Desert Color, Washington Fields, and Ivins where the sealer wore off within a year due to high usage or improper products.
Simple test to check your sealer:
Drip a small amount of water on your stone. If it beads up and sits on top, the sealer is still working. If it soaks in or darkens the stone, it’s time to reseal.
Stone types and sealing needs:
- Granite: Once every 1–2 years, depending on use
- Marble: Every 6–12 months, especially in kitchens and bathrooms
- Travertine/Limestone: Every 6–12 months, especially in showers or outdoor areas
- Onyx: Needs regular sealing due to softness and sensitivity
What happens during professional sealing? At Sky’s Stone Care, our sealing service includes:

Sealing is often paired with polishing, honing, or chip repair as part of routine maintenance.
