Understanding the Importance of Sealing

Having been in the industry for over 20 years, one undeniable truth has emerged: all sealing products are different. It's crucial to understand what’s best for your specific stone type and finish. Knowing how sealing will alter the surface and the benefits it provides is essential for making an informed decision.

Natural stone surfaces are inherently porous, and while engineered stones are less so, they still benefit from proper sealing. Untreated surfaces with microscopic capillaries attract and absorb liquids, much like a chalk stick absorbs moisture. This makes sealing a vital step to prevent stains and protect your stone's integrity.

The Testing Process: Finding the Right Sealer

Given the myriad of sealers available, it’s wise to conduct a test before making your final selection. Apply the chosen sealer to a test tile or off-cut to observe how it interacts with the stone. Many suppliers offer this service free of charge, but we can also conduct these tests for a fee.

The goal is to assess whether the sealer effectively blocks absorption. A well-sealed surface will resist both water and oil-based liquids, preventing them from penetrating and causing stains. This test should be carried out after the sealer has fully cured, leaving the liquid on the sealed surface for at least one hour to check for absorption.

Aesthetic Considerations: Natural vs. Enhanced Finish

Beyond protection, sealers also impact the appearance of your stone. Do you prefer a natural, invisible finish, or are you drawn to the rich, color-enhanced wet look? Each option offers distinct aesthetic outcomes, and it's important to choose one that aligns with your vision.

Keep in mind that most stone penetrating sealers are irreversible. Premium sealers tend to penetrate deeper into the stone’s structure, creating a more permanent bond. This makes the initial choice critical, as reversing a poorly chosen sealer can be an expensive and often impossible task.

Note: The advice provided on this page pertains to the use of penetrating sealers for stone surfaces. We do not recommend the use of topical sealers, which are largely outdated except in high-traffic commercial areas. Topical sealers can cause long-term issues by blocking the stone’s natural pores, leading to surface degradation.
