To seal or not to seal? That is the question!

Sealing stone paving, such as Indian sandstone, is a common practice to enhance its appearance and protect it from stains and weathering. However, whether you should seal your paving depends on several factors:

Advantages of Sealing:

• Stain Resistance: Sealers can help prevent oil, grease, and water-based stains from penetrating the stone. Sealing can make cleaning spills easier whilst helping to maintain the patio’s pristine condition.
• Enhanced Appearance: Some sealers can enhance the natural colours of the stone, giving it a richer look.
• Protection Against Weathering: Sealing can provide a protective layer against the elements, potentially extending the lifespan of your paving.

Considerations Before Sealing:

• Natural Look: Some sealers may alter the stone’s appearance, potentially leaving a sheen that doesn’t match the original look.
• Moisture Movement: Improper sealing can hinder the stone’s natural moisture movement, leading to issues like blistering and cloudiness.
• Maintenance: Sealed surfaces may require reapplication over time, depending on the type of sealer used and environmental conditions. In areas of full sun the sealer burns off quickly and you would need to reseal approximately 12-18 months.

Recommendations:

• Assess Your Priorities: If maintaining the stone’s natural appearance and allowing it to breathe are important to you, sealing might not be necessary.
• Choose Quality Products: If you decide to seal, opt for high-quality, breathable sealers such as designed for natural stone to minimize potential drawbacks.
• Consult Professionals: Consider seeking advice from professionals or reputable suppliers to select the appropriate sealer and ensure proper application.

In summary, sealing Indian stone paving is a personal choice based on your aesthetic preferences and maintenance priorities. Sealing can enhance the color, protect against stains, and make cleaning easier, but it can also alter the natural look of the stone and require ongoing maintenance. Weighing the benefits of protection and longevity against the potential for changes in appearance and the need for reapplication will help you make an informed decision.
