Natural stone countertops, floors, and showers bring beauty and value to any home. From elegant marble to durable granite, stone has been a top choice for homeowners who want luxury and longevity. But here’s the big question many people ask: is sealing stone surfaces really necessary, or is it just an extra step?
The short answer: yes—sealing is absolutely necessary if you want your stone to stay protected, stain-free, and looking like new. Let’s dive into why sealing matters, how it works, and how often you should do it.
Why Does Stone Need Sealing?
Stone might look solid and glossy on the surface, but most varieties are naturally porous. That means liquids, oils, and dirt can seep into the stone, leaving behind stains, discoloration, and even damage over time.
Unsealed stone is especially vulnerable to:
-
Food and drink stains – wine, coffee, juice, and sauces
-
Oil-based damage – cooking oils, lotions, cosmetics
-
Etching – dull spots from acidic foods like lemon or vinegar (particularly on marble)
-
Moisture damage – mold and mildew in bathrooms or showers
Sealing creates a protective barrier that repels moisture and slows absorption, giving you time to wipe up spills before they soak in.
Do All Stone Surfaces Need Sealing?
Not every stone is equally porous, but most stones benefit from sealing.
-
Granite: Some granite is naturally dense, but many varieties still need sealing to resist oil and wine stains.
-
Marble, Limestone, and Travertine: Very porous and prone to etching—sealing is essential.
-
Slate: Often requires sealing to prevent staining and flaking.
-
Quartzite: Harder than granite but still porous enough to need sealing.
Even if your stone feels dense, skipping sealing is a gamble that can shorten the lifespan and beauty of your investment.
How Often Should You Seal Stone?
The frequency of sealing depends on:
-
Stone type – Softer stones need sealing more often.
-
Usage – A busy kitchen countertop will need sealing more frequently than a guest bathroom vanity.
-
Product used – High-quality sealers can last longer than basic options.
A simple way to test if your stone needs sealing: sprinkle a few drops of water on the surface. If the stone darkens within a few minutes, it’s time to reseal.
