Does Natural Quartzite Need To Be Sealed? Yes, Here’s Why! With stunning appearance and high durability, it’s no wonder why quartzite countertops have gained popularity in recent years. But the question is: does quartzite need to be sealed? The Nature of Quartzite Quartzite is a naturally occurring metamorphic rock formed from quartz-rich sandstone. Through intense heat and pressure, the sandstone transforms into quartzite, creating a dense, hard material. This process imparts quartzite with remarkable strength and a beautiful, marble-like appearance, making it a popular choice for countertops. When compared to other countertop materials such as granite, marble, and quartz, quartzite stands out for its unique combination of beauty and durability. While it is harder and more resistant to scratching than marble, it shares marble’s elegant veining patterns. But unlike engineered quartz, which is non-porous, natural quartzite has varying degrees of porosity, which is why sealing becomes vital. Understanding Quartzite’s Porosity and Durability One common misconception is that quartzite is as non-porous as quartz. In reality, quartzite is a natural stone with varying porosity levels, depending on its mineral composition and density whereas engineered quartz is made with resins which creates less porosity. This porosity in quartzite means that, without proper sealing, it can absorb liquids, leading to potential staining and etching over time. Why Sealing Quartzite is Essential Importance of Sealing for Stain Resistance Sealing quartzite countertops is needed to improve their stain resistance. An impregnating sealant fills the pores of the quartzite, preventing liquids such as wine, coffee, and oil from deeply penetrating the stone. Without this protection, these substances can seep deep into the stone’s pores, causing stains that may become permanent. Preserving Appearance and Longevity Sealing helps maintain the appearance of quartzite countertops by preventing unsightly stains from penetrating the surface. While it does not affect the stone’s natural luster, an impregnating sealer provides essential protection against spills and everyday use. This preserves the countertop’s beauty and maintains its elegance and durability without compromising the stone’s inherent qualities. Debunking Myths About Quartzite Maintenance A common myth is that all quartzites are the same and completely maintenance-free. In reality, quartzite varies in density—some types are extremely dense and resistant to moisture absorption while others are more porous and prone to staining. Without proper sealing, the more absorbent varieties can absorb liquids, which may lead to discoloration over time. The Benefits of Sealing Quartzite Countertops Maintaining Aesthetics Sealing quartzite countertops is important for preserving their natural beauty, and impregnating sealers do not change the appearance or color of the stone. However, applying a color enhancer is an optional choice for those who want to enrich the stone’s natural hues and create a more vibrant look. Opting for a color enhancer is purely a matter of client preference and is not a necessary step in the sealing process. This tailored approach allows homeowners to either maintain the stone’s original aesthetic or augment it to add a different visual appeal to their space. Enhancing Durability and Resisting Damage A properly sealed quartzite countertop is more resistant to staining, etching, and other forms of damage. For sealers, there are impregnating sealers and topical sealers. While impregnating sealers penetrate the stone and seal up the pores, topical sealers, similar to More AntiEtch, form a protective layer over the countertop. Long-Term Cost Savings Investing in sealing quartzite countertops can lead to significant long-term cost savings. By protecting the stone from stains and damage, sealing reduces the need for restoration or replacements. Guide to Sealing Quartzite Countertops Choosing the Right Sealant Selecting the appropriate sealant for your quartzite countertop is crucial for effective protection. Homeowners should consult their fabricator for a personalized recommendation. For particularly dense quartzite, an impregnating sealer like Stonetech Bulletproof can be effective. However, if your quartzite is prone to moisture absorption, consider using a more specialized sealer such as MORE® AntiEtch® for optimal protection. The following instructions for sealing your quartzite countertops work with an impregnating sealer. Applying a sealer such as MORE® AntiEtch® must be performed by a certified professional. At Connecticut Stone, we are proud to offer this specialized service to protect your surfaces. Step-by-Step Instructions on How to Seal Quartzite Countertops Clean the Surface: Thoroughly clean the countertop with a pH-neutral stone cleaner to remove any dirt, grease, or stains. Apply the Sealant: Using a clean cloth or brush, apply the sealant evenly across the countertop surface. Follow the manufacturer’s instructions for the recommended amount and application technique. Let It Penetrate: Allow the sealant to penetrate the stone for the specified time, usually 15-20 minutes. Wipe Off Excess: After the penetration time, wipe off any excess sealant with a clean, dry cloth. For particularly absorbent quartzites, additional coats of sealer may be necessary. Apply until the sealer takes longer to absorb, indicating filled pores, but ensure it doesn’t dry on the surface as it can become difficult to remove. Allow to Cure: Let the sealant cure for the recommended time, typically 24-48 hours, before using the countertop. Maintenance Tips to Ensure the Sealant’s Longevity Regular Cleaning: Clean quartzite countertops regularly with a pH-neutral cleaner to maintain the sealant’s effectiveness. Avoid Harsh Chemicals: Steer clear of acidic or abrasive cleaners that can wear down the sealant. Reapply as Needed: Depending on usage and wear, reapply the sealant every 1-2 years to ensure continued protection. FAQs About Sealing Quartzite Countertops How often do quartzite countertops need to be sealed? Quartzite countertops typically need to be sealed every 1-2 years, depending on usage and wear. Can a sealant make quartzite countertops completely damage-proof? While sealing significantly enhances quartzite’s resistance to stains and damage, it does not make the countertops completely impervious. Regular maintenance is still necessary. Recognizing signs that your quartzite countertops need resealing? If water no longer beads on the surface or if the countertop begins to absorb liquids and stain easily, it’s time to reapply the sealant. Choosing the Right Stone Sealing quartzite countertops is essential to preserve their beauty and functionality, and with proper care and maintenance, homeowners can enjoy the lasting benefits of sealing their countertops for years to come.
