Stone Sealing and Enhancing

What It Is and Why It’s Essential for Long-Term Protection

Natural stone is porous—meaning it can absorb liquids, trap dirt, and become stained or damaged if left unprotected. Sealing is a crucial step in preserving the beauty and performance of stone surfaces, both indoors and out. Whether it’s a newly installed surface or one that’s just been restored, sealing helps guard against stains, moisture intrusion, and everyday wear.

In some cases, enhancing sealers can also deepen the color and richness of the stone for a more dramatic or finished appearance. A professional stone care contractor can recommend the right type of sealer based on the stone, location, and how the surface is used.

Penetrating Sealers – Invisible Protection from Within

Penetrating sealers soak into the stone, filling microscopic pores to prevent liquids from being absorbed. They don’t change the look or feel of the surface but provide critical protection against stains and moisture.

Enhancing Sealers – Enrich Natural Color and Texture

Some homeowners or designers want to deepen the tone of natural stone for a richer, “wet look” without adding shine. Enhancing sealers do just that—while still offering the same protective benefits as traditional penetrating sealers.

Topical Sealers – When Added Surface Protection Is Needed

In certain cases, a topical sealer may be used to create a thin layer of protection on the surface, especially in areas subject to harsh use. These are less common for interior natural stone but may be appropriate in specific situations, such as exterior hardscapes.

Sealer Selection – Matching the Product to the Stone

Different stones—like marble, granite, limestone, or slate—have different porosities and needs. A professional understands how to match the correct sealer type and formula to the surface for optimal performance and longevity.

Periodic Reapplication – Keeping Protection in Place

Sealers don’t last forever. Depending on use and exposure, they may need to be reapplied every 1 to 3 years. A stone care professional can inspect and test the surface to determine when it’s time to reseal.
