Natural stone surfaces like granite, marble, slate, travertine, and limestone are popular for their beauty, durability, and timeless appeal. But while they’re strong and attractive, natural stone is also porous—meaning it can absorb liquids, oils, and stains if left unprotected. That’s where sealing comes in.
What Does Sealing Do?
Sealing your natural stone creates an invisible barrier that repels moisture, dirt, and contaminants. It helps keep your stone looking new, prevents discoloration, and protects it from everyday wear and tear. A properly sealed surface won’t absorb spills as quickly, giving you time to wipe them up before they stain.
Why Stone Needs Protection
Natural stone is formed through geologic processes and contains pores and tiny fissures. Without a sealant, things like water, wine, oil, and even acidic cleaners can seep into the surface. This can cause etching, staining, and in some cases, long-term damage. High-traffic areas like kitchens and bathrooms are especially vulnerable.
In outdoor settings, stone can be damaged by rain, frost, and UV rays. Sealing helps shield the stone from the elements and minimizes the risk of cracks and erosion over time.
Sealing Enhances Appearance
A quality sealer doesn’t just protect—it can also enhance the natural color and texture of the stone. Some sealers offer a “wet look” that deepens the stone’s hues, while others preserve a more natural matte finish. Either way, sealing gives your stone a cleaner, richer look.
How Often Should You Seal Natural Stone?
The frequency depends on the type of stone, its location, and the sealer used. As a general rule, natural stone should be resealed every 1–3 years. You can perform a simple water test by dripping a few drops onto the surface. If the water is quickly absorbed and darkens the stone, it’s time to reseal.
Don’t Skip This Step
Skipping the sealing step may save time or money in the short term, but it can lead to permanent stains and expensive repairs later. Sealing is a relatively quick and affordable way to protect your investment and maintain the beauty of your stone for years to come
Whether it’s a marble countertop, travertine floor, or granite patio, sealing your natural stone is a smart, proactive step. It helps keep surfaces cleaner, protects against stains and etching, and ensures your stone continues to impress—day after day, year after year.
