The Timeless Appeal of Sandstone for Pool Coping

Why Sandstone Remains a Premium Choice for Pools

Sandstone has been a preferred building material in Australia for over two centuries, gracing everything from heritage landmarks to modern architectural masterpieces. Its natural elegance, durability, and versatility make it an exceptional choice for pool coping, provided the correct type is selected.

Key Benefits of Sandstone for Pool Areas

✅ Slip-Resistant & Safe

• Unlike polished or highly dense materials, sandstone has a naturally grippy surface, reducing the risk of slipping in wet areas.
• A textured finish enhances slip resistance, making it ideal for families and high-traffic pools.

✅ Cool Underfoot

• Unlike bluestone or granite, which absorb and retain heat, sandstone stays cooler in direct sunlight, providing a comfortable barefoot surface.
• Perfect for Australian summers, when poolside surfaces can become too hot to walk on.

✅ Timeless Beauty & Versatility

• Sandstone offers a natural, high-end look that complements modern and heritage homes.
• Sandstone allows for customised aesthetics that blend seamlessly with your outdoor space. It is available in various colours, from warm golds and soft creams to rich browns, pinks & whites.

✅ Proven Durability

• Sandstone has been used for centuries in Australian architecture. Proper care ensures decades of performance in pool environments.

It is suitable for chlorine and freshwater pools when selected from high-density, premium-grade varieties.

Addressing the Myths About Sandstone and Pool Coping

Debunking the Biggest Misconceptions About Sandstone Around Pools

Several myths are circulating about sandstone and its suitability for pool coping, leading some homeowners, architects, and landscapers to believe it is a poor choice.

The reality? Sandstone has been successfully used around pools for decades when the correct type of sandstone is selected, installed, and maintained correctly.

Here, we break down the most common myths and set the record straight.

Myth 1: “Sandstone is Too Porous for Pool Coping”

🔎 Reality: Not all sandstone is highly porous – high-quality, dense sandstone perfectly suits pool environments.

One of the biggest misconceptions about sandstone is that it absorbs too much water, making it unsuitable for wet areas. However, not all sandstone is the same.

✅ Premium, high-density sandstone has naturally low porosity, making it resistant to water absorption.

✅ Correct sealing further reduces porosity, preventing excessive moisture retention.

✅ Proper drainage and installation ensure that water doesn’t pool on the stone, protecting it for the long term.

Myth 2: “Sandstone Erodes Easily Due to Salt and Acid Exposure”

🔎 Reality: High-quality, properly sealed sandstone is resistant to salt attack and chemical damage.

Some varieties of sandstone are indeed more susceptible to salt damage, but this does not apply to all sandstone. When selecting the correct grade of sandstone and following best practices for sealing, installation and maintenance:

✅ High-quality sandstone can withstand pool environments with ease. 

✅ Penetrating, consolidating sealers create a protective barrier against saltwater and pool chemicals.

✅ Proper cleaning and maintenance prevent chemical buildup, ensuring longevity.

Myth 3: “Sealing Does Not Make Sandstone Salt-Safe”

🔎 Reality: High-performance sealers significantly enhance sandstone’s durability, reducing moisture absorption and salt penetration.

A common argument is that sealers don’t make sandstone salt-safe. While it’s true that sealers don’t chemically alter the stone, they play a crucial role in reducing porosity, binding the stone particles together, reinforcing the stone, and preventing surface damage.

✅ Penetrating and consolidating sealers are an invisible barrier, reinforcing the stone and limiting water and salt absorption.

✅ High-quality sealers protect against staining, chemical damage, and efflorescence.

✅ Resealing, per sealer manufacturer recommendations, enhances sandstone’s longevity and appearance.

Myth 4: “Sandstone Deteriorates Quickly in Wet Environments”

🔎 Reality: Sandstone has been used for centuries in high-exposure areas, proving its resilience.

Some claim that sandstone cannot handle prolonged exposure to water, but this ignores its long history of use in outdoor structures, coastal buildings, and public spaces.

✅ Australian sandstone, which is constantly exposed to moisture, has been used in fountains, harbour walls, and historical landmarks.

✅ Correct maintenance and sealing ensure that sandstone remains structurally sound and visually stunning.

✅ Choosing a premium-grade sandstone ensures superior longevity in pool environments.

Best Practices for Using Sandstone Around Pools

How to Ensure Sandstone Performs Beautifully for Years

We’ve established that high-quality sandstone is durable, safe, and aesthetically stunning for pool surrounds. However, like any natural material, proper selection, installation, and maintenance are crucial in ensuring its longevity and performance.

Here’s everything you need to know about correctly using sandstone around your pool.

1. Choose the Right Type of Sandstone

Not all sandstone is the same – density, porosity, and natural resistance vary across quarries and stone grades. The right high-quality, salt-resistant sandstone is essential for optimal performance in wet environments.

What to Look for in Pool-Safe Sandstone

✅ Dense, low-porosity sandstone to minimise water absorption.

✅ Tougher, higher-quality sandstone varieties that withstand salt exposure.

✅ A well-tested and proven supply from a reputable quarry. 

✅ Natural slip-resistant finishes for enhanced poolside safety.

2. Install Sandstone Correctly to Prevent Damage

Correct installation is just as important as choosing the right stone. A poorly installed sandstone pool surround can lead to moisture issues, shifting, and premature wear.

Best Practices for Sandstone Installation Around Pools

✅ Use high-quality adhesives and grout designed for wet environments.

✅ Ensure proper drainage to prevent water from pooling beneath the stone.

✅ Allow for adequate expansion joints to accommodate temperature fluctuations.

✅ Work with experienced professionals who specialise in natural stone pool installations.

3. Seal the Sandstone to Enhance Its Longevity

Sealing sandstone is one of the most effective ways to protect it from moisture, stains, and salt exposure. While premium-quality sandstone is naturally resilient, sealing provides an added layer of defence, ensuring decades of beauty and durability.

How to Seal Sandstone for Pool Areas:

✅ Use a high-quality, penetrating consolidating sealer designed for natural stone.

✅ Apply the consolidating sealer before and the general sealer after installation for maximum protection.

✅ Reapply the sealer as directed by the Sealant manufacturer to maintain protection and care of the stone.

✅ Choose a breathable sealer that allows the stone to release trapped moisture while keeping out excess water.

4. Maintain Your Sandstone to Keep It Looking Pristine

Like all outdoor materials, sandstone benefits from regular care to maintain its original beauty. Fortunately, sandstone is low maintenance and requires basic cleaning and occasional resealing.

Best Practices for Sandstone Pool Maintenance

✅ Use a pH-neutral cleaner to prevent chemical damage.

✅ Avoid using high-pressure tools to clean. Instead, sweep and rinse regularly to remove debris and prevent buildup.

✅ Avoid harsh, acidic cleaners, as they can degrade natural stone.

✅ Inspect the sealer every few years and reapply if needed.

Fact: Sandstone is a Long-Lasting and Elegant Choice for Pools

When properly selected, installed, and maintained, sandstone remains one of the best choices for pool coping. It offers a stunning, durable, and safe solution for modern and traditional outdoor designs.

Key Takeaways

✅ Choose high-quality, dense sandstone for superior durability.

✅ Install sandstone correctly with proper drainage and adhesive solutions. 

✅ Apply a high-quality penetrating consolidating sealer to protect against moisture and salt exposure.

✅ Regular cleaning and maintenance will ensure sandstone looks pristine for decades.
