Welcome to Roman Building & Landscapes with over 40 years of experience.

Indian Sandstone is a popular choice for patios and walkways, known for its natural beauty and durability. However, like any outdoor surface, it requires regular maintenance to keep it looking its best. At Roman Building & Landscapes, we want to help you ensure that your Indian Sandstone paving remains as stunning as the day it was installed. Here are some tips on how to maintain your Indian Sandstone paving.

1. Regular Cleaning
Regular cleaning is essential to prevent the buildup of dirt, algae, and moss, which can make your sandstone look dull and slippery. Here’s how to do it:

– Sweeping: Sweep your sandstone paving regularly with a stiff broom to remove leaves, dirt, and debris.
– Washing: Use a garden hose or a low-pressure power washer to rinse off surface dirt. Avoid using high pressure, as it can damage the stone.
– Soapy Water: For a deeper clean, mix a solution of warm water and mild dish soap. Use a soft brush to scrub the surface gently. Rinse thoroughly with clean water to remove any soap residue.

2. Preventing Stains
Stains can mar the beauty of your sandstone. To prevent staining:

– Sealant: Apply a high-quality stone sealant to your sandstone paving. This will create a protective barrier against stains from oil, food, and other substances. Sealants should be reapplied every 1-2 years, depending on the wear and tear.
– Clean Spills Immediately: If you spill something on the sandstone, clean it up right away. Use a cloth to blot (not rub) the spill, then rinse the area with water.

3. Removing Stains
If your sandstone does get stained, here are some tips for removing common types of stains:

– Organic Stains (leaves, algae, etc.): Use a solution of water and bleach (1 part bleach to 10 parts water). Scrub the area with a brush, then rinse thoroughly.
– Grease and Oil Stains: Apply a poultice made from baking soda and water to the stain. Let it sit for a few hours, then rinse off with water.
– Rust Stains: Use a commercial rust remover that is safe for natural stone. Follow the product instructions carefully.

4. Preventing Algae and Moss Growth
Algae and moss can make your sandstone slippery and unsightly. Here’s how to keep them at bay:

– Sunlight: Algae and moss thrive in damp, shady areas. Trim back any overhanging branches or plants to allow more sunlight to reach the paving.
– Drainage: Ensure proper drainage to prevent water from pooling on the surface. This might involve adjusting the slope of the paving or improving the surrounding landscape.
– Algaecide: Apply a biodegradable algaecide to the sandstone to inhibit the growth of algae and moss. Reapply as recommended by the manufacturer.

5. Repairing Damage
Despite your best efforts, your sandstone paving might get damaged over time. Here’s what to do:

– Cracks and Chips: Small cracks and chips can be filled with a matching stone filler. For larger repairs, it’s best to consult a professional.
– Loose Pavers: If a paver becomes loose, it should be lifted, the area beneath it re-leveled, and the paver re-laid securely.

6. Seasonal Maintenance
Different seasons bring different challenges. Here’s how to care for your sandstone paving throughout the year:

– Spring and Summer: Regularly sweep and wash your paving. Apply a sealant if needed.
– Autumn: Clear away fallen leaves and other debris promptly to prevent staining.
– Winter: Avoid using de-icing salts on sandstone, as they can cause damage. Instead, use sand or grit to provide traction on icy surfaces.


Maintaining Indian Sandstone paving doesn’t have to be a daunting task. With regular care and the right techniques, you can keep your paving looking beautiful for years to come.
