Why Exposed Aggregate Sealers are a Must for Every Homeowner

Exposed aggregate concrete is a popular choice for driveways, walkways, and patios due to its durability and aesthetic appeal. However, to maintain its beauty and extend its lifespan, sealing the exposed aggregate is a crucial step that should not be overlooked. This comprehensive article explores the myriad benefits of using exposed aggregate sealers and why they are essential for every homeowner.

Exposed aggregate concrete is a form of decorative concrete achieved by removing the outer surface of cement paste to uncover the decorative aggregates (such as stones and pebbles) within the concrete. Homeowners opt for exposed aggregate because it offers a robust surface with a natural, varied texture that complements any home’s exterior décor. Despite its durability and resistance to wear, exposed aggregate is susceptible to damage from environmental elements without proper protection.

What are Exposed Aggregate Sealers?

Exposed aggregate sealers are specifically formulated products designed to protect and enhance the look of exposed aggregate surfaces. These sealers provide a protective layer that resists water penetration, stains, and other harmful substances. Available in different finishes, such as matte or glossy, they can also enhance the natural colour of the aggregate, making it more striking and visually appealing. It’s an essential investment for prolonging the life and beauty of exposed aggregate installations around the home.

Benefits of Sealing Exposed Aggregate

Protection Against Stains and Damage

One of the primary reasons to apply a sealer to exposed aggregate surfaces is to protect them from staining and erosion. Spills of oil, wine, or other substances can permanently discolour unsealed aggregate. Furthermore, environmental factors like rain, frost, and heat can gradually degrade the surface. Applying a sealer creates a barrier that minimises these risks, helping to maintain the surface’s aesthetic and functional qualities over time.

Enhancing Appearance

A sealer can significantly enhance the appearance of exposed aggregate by enriching the colour depth and providing either a sleek wet look or a natural matte finish. This visual enhancement is crucial not only for personal enjoyment but also for improving curb appeal, which can increase property values. Moreover, regular maintenance of the sealer ensures that this decorative investment remains attractive year after year.

Choosing the Right Sealer

Selecting the appropriate sealer is pivotal. Water-based sealers are eco-friendly and easier to apply, whereas solvent-based sealers are known for their durability and enhanced colour enrichment. Crommelin's DiamondCoat Exposed Aggregate & Polished Concrete Sealer is an example of a high-quality sealer that provides excellent protection and aesthetic enhancement for a variety of exposed aggregate surfaces. It is crucial that the selected sealer complies with local environmental regulations and is appropriate for the climate in which it will be used.

Application of Exposed Aggregate Sealer

Proper application is essential for ensuring the maximum effectiveness of the sealer. The surface should be thoroughly cleaned and dried before application. Apply the sealer evenly using a sprayer, roller, or brush, ensuring that it penetrates all nooks and crannies of the aggregate. In some cases, two coats are advisable, with the second coat applied perpendicular to the first to ensure complete coverage. Following the manufacturer’s instructions for drying time will yield the best results.

Maintenance Tips for Sealed Surfaces

Maintaining a sealed exposed aggregate surface involves regular cleaning with mild, non-abrasive cleaning agents to avoid damaging the sealer layer. Periodic reapplication of the sealer is recommended, typically every 2-3 years, depending on the level of exposure to traffic and the elements. Inspecting the surface annually for signs of wear or erosion can help in scheduling maintenance before significant damage occurs.

Conclusion

Sealing exposed aggregate surfaces is a wise investment for any homeowner. It not only protects the surface from environmental and man-made damages but also enhances the overall look of the home. For best results, homeowners should choose high-quality sealers and ensure they are correctly applied and maintained. A
