How Unsealed Stone Can Easily Become Damaged

Stone surfaces have long been celebrated for their natural beauty, durability, and timeless elegance. From luxurious marble countertops to rugged granite flooring, stone surfaces add a touch of sophistication to any space. However, maintaining the pristine condition of these surfaces requires more than just regular cleaning. One crucial aspect of stone care that is often overlooked is sealing. Unsealed stone is highly susceptible to various forms of damage, which can significantly diminish its aesthetic appeal and structural integrity over time. In this comprehensive blog, we will explore the myriad ways unsealed stone can become damaged and offer insights into effective stone care practices.

Understanding Stone Porosity

Before diving into the specific types of damage that can affect unsealed stone, it is essential to understand the inherent properties of natural stone. Most natural stones are porous to varying degrees. This porosity means that the stone has tiny, interconnected capillary channels that can absorb liquids and other substances. The level of porosity varies among different types of stone:

Granite: Generally less porous than other stones, making it more resistant to stains and moisture penetration.

Marble: Highly porous and prone to staining and etching from acidic substances.

Limestone: Extremely porous and susceptible to water damage and staining.

Travertine: Also highly porous and can easily absorb liquids and other contaminants.

The porosity of stone makes sealing a critical step in protecting it from damage.

Types of Damage to Unsealed Stone


Common Culprits: Liquids such as wine, coffee, oil, and juice are notorious for staining unsealed stone surfaces. When these liquids penetrate the stone, they can leave behind unsightly marks that are difficult to remove.

Prevention and Care: Sealing creates a protective barrier that prevents liquids from seeping into the stone. For already stained surfaces, specialized stone cleaners and poultices can help lift stains.

Water Damage

Signs of Water Damage: Water spots, mineral deposits, and efflorescence (a white, powdery residue) are common indicators of water damage in unsealed stone.

Impact: Prolonged exposure to moisture can weaken the stone, leading to cracks and structural deterioration. This is particularly problematic for outdoor stone surfaces exposed to rain and humidity.

Prevention and Care: Regular sealing and prompt cleaning of spills can mitigate water damage. Using water repellents in high-moisture areas can provide additional protection.


Acidic Substances: Acidic substances like vinegar, citrus juices, and certain cleaning products can cause etching on stone surfaces, especially marble and limestone. Etching appears as dull spots or light-colored marks where the acid has reacted with the stone.

Prevention and Care: Sealing does not entirely prevent etching but makes it easier to clean up acidic spills before they cause damage. Avoiding acidic cleaners and using pH-neutral products is crucial.

Scratches and Abrasions

Sources: Foot traffic, moving furniture, and using abrasive cleaning tools can cause scratches and abrasions on stone surfaces.

Impact: Over time, these scratches can accumulate, leading to a worn and unattractive appearance.

Prevention and Care: Regular sealing can help reduce the likelihood of scratches by providing a smoother surface. Using rugs and mats in high-traffic areas and employing gentle cleaning methods can further protect the stone.

Biological Growth

Mold and Mildew: Unsealed stone in damp environments is susceptible to mold and mildew growth, which can discolor the stone and pose health risks.

Algae and Lichen: Outdoor stone surfaces can also be affected by algae and lichen, leading to slippery and unsightly surfaces.

Prevention and Care: Sealing stone surfaces reduces moisture absorption, inhibiting biological growth. Regular cleaning with appropriate solutions can keep these issues at bay.

Thermal Shock

Sudden Temperature Changes: Unsealed stone exposed to sudden temperature changes, such as placing hot pots on a cold countertop or exposure to freezing temperatures, can experience thermal shock.

Impact: Thermal shock can cause cracks and other structural damage to the stone.

Prevention and Care: Sealing can help stabilize the stone’s surface, reducing the risk of damage from temperature fluctuations. Using trivets and coasters can protect stone countertops from thermal shock.

Best Practices for Stone Care

Regular Sealing

Frequency: The frequency of sealing depends on the type of stone, its location, and usage. High-traffic areas and highly porous stones may require more frequent sealing, typically every 6 to 12 months.

Product Selection: Use high-quality sealers specifically designed for your type of stone. 

Penetrating sealers are often recommended as they provide protection without altering the stone’s appearance.

Proper Cleaning Techniques

pH-Neutral Cleaners: Use pH-neutral, stone-specific cleaners to avoid damaging the stone. Avoid acidic or abrasive cleaners.

Routine Cleaning: Regularly clean stone surfaces with a soft cloth or mop to remove dirt and debris. Promptly wipe up spills to prevent staining.

Protective Measures

Rugs and Mats: Place rugs and mats in high-traffic areas and entryways to reduce the amount of dirt and grit that can scratch stone surfaces.

Coasters and Trivets: Use coasters and trivets under hot or acidic items to prevent etching and thermal shock.

Addressing Stains and Damage Promptly

Stain Removal: For stubborn stains, use poultices and stone-specific stain removers. Follow the manufacturer’s instructions for best results.

Professional Restoration: For significant damage or deep stains, consider professional stone restoration services. Experts can assess the damage and recommend appropriate treatments.

The Long-Term Benefits of Sealing Stone

Investing in regular sealing and proper stone care practices offers numerous long-term benefits:

Enhanced Appearance: Sealed stone retains its natural beauty, with a polished and well-maintained look.

Increased Durability: Sealing strengthens the stone’s surface, making it more resistant to wear, scratches, and other forms of damage.

Easier Maintenance: A sealed stone surface is easier to clean and maintain, reducing the time and effort required for upkeep.

Cost Savings: Preventing damage through sealing and proper care reduces the need for expensive repairs and replacements.
