How to Protect Sandstone from Harsh Weather Conditions
Sandstone is a beautiful, natural material often used in outdoor spaces to create a timeless and rustic aesthetic. Whether it’s used for patios, walkways, or retaining walls, sandstone can elevate the look of any property. However, being a porous and soft stone, it’s particularly susceptible to damage caused by harsh weather conditions. From relentless sun exposure to freezing temperatures and heavy rain, the elements can take a toll on your sandstone surfaces if they aren’t properly protected. Here’s how you can safeguard your outdoor sandstone from weather-related damage to ensure it remains in pristine condition for years to come.
Apply a High-Quality Sealer
One of the best ways to protect your sandstone from the elements is by applying a high-quality stone sealer. Sealing sandstone creates a barrier against moisture, dirt, and stains, preventing water from seeping into the pores of the stone and causing erosion. When choosing a sealer, opt for one designed for porous stone like sandstone and that provides UV protection, as prolonged sun exposure can cause fading and discolouration.
Ensure that the sealer is applied evenly, and always follow the manufacturer’s guidelines. Depending on the type of sealer, it may need to be reapplied every few years to maintain its protective qualities.
Prevent Frost Damage with Proper Drainage
If you live in an area where temperatures drop significantly in the winter, frost damage is a real concern for sandstone surfaces. When water enters the porous stone and freezes, it expands, leading to cracks and structural damage. To prevent this, make sure your outdoor areas have proper drainage to avoid water pooling on the surface. Regularly check for and clear any blockages in drainage channels, ensuring water can flow away from the sandstone, especially during heavy rain or melting snow.
Additionally, you may want to consider elevating sandstone features slightly to avoid direct contact with water on the ground, which can freeze during winter.
Protect Against Sun Damage
Australia’s strong sun can be particularly harsh on sandstone, causing it to fade over time. UV rays can bleach the natural colours of sandstone, making it look dull and worn. To protect against sun damage, ensure the stone is sealed with a UV-resistant product. For additional protection, you might consider incorporating shade features, such as pergolas or large umbrellas, to shield the sandstone during the hottest parts of the day.

Regular Cleaning and Maintenance
Keeping your sandstone clean is another important aspect of protecting it from harsh weather. Dirt and debris can trap moisture, leading to mildew growth and staining. Regularly sweep or wash your sandstone surfaces to remove loose dirt and leaves. For deeper cleaning, use a mild, pH-neutral cleaner specifically designed for natural stone. Avoid using harsh chemicals or high-pressure washers, as these can damage the surface.
In addition to cleaning, inspect your sandstone periodically for signs of wear and tear. Small cracks or chips should be addressed immediately to prevent them from worsening, especially if they’re exposed to rain or frost.
Use Sandstone-Safe Products
Whenever you’re maintaining your sandstone, it’s essential to use products that are specifically formulated for natural stone. Many common cleaners, especially acidic ones, can erode the surface of sandstone and accelerate weathering. Choose products that are gentle and designed to preserve the integrity of the stone. This applies to sealers, cleaners, and even brushes or tools used to clean the surface.
Final Thoughts
Sandstone is an investment in both beauty and function for your outdoor spaces, but it requires proper care and protection to withstand Australia’s diverse weather conditions. By applying a sealer, ensuring adequate drainage, protecting from UV rays, and maintaining regular cleaning, you can prolong the life of your sandstone and keep it looking stunning for years to come.
