Indian sandstone is one of the most admired natural stones across the world. Known for its timeless charm, durability, and versatility, this stone has become a favourite for patios, gardens, wall cladding, pool surrounds, and even decorative stepping stones. Its natural colours and textures create an elegant, earthy look that never goes out of style. However, like all natural materials, sandstone requires proper care to maintain its beauty and strength for years to come.
At Runjhun Export, we not only supply and export premium sandstone, limestone, flagstone, circular stone, and stepping stone varieties across the globe, but we also guide our customers on how to look after them. With the right cleaning and maintenance practices, your natural stone will stay strong and attractive for decades, even when exposed to outdoor elements.
Why Indian Sandstone Needs Proper Care
Sandstone, sometimes referred to as sand stone, forms naturally over millions of years. Its slightly porous nature means it can absorb moisture, dust, and dirt if not maintained properly. Outdoor installations are especially prone to rain, algae growth, moss, and pollution. Without care, this can dull its surface over time.
The good news is that sandstone is relatively easy to clean and maintain with simple, consistent care.
Whether you’ve installed paving slabs, flagstone pathways, wall cladding, or circular stones, these methods will help you preserve their natural beauty.
Step 1: Regular Cleaning with Water
The simplest way to care for sandstone is by rinsing it regularly with clean water. A garden hose or a bucket of water will remove dust, pollen, and light dirt before it settles deep into the pores.
- For patios or courtyards: Rinse once or twice a week.
- For wall cladding: Wipe down occasionally with a damp cloth.
Avoid using harsh chemicals, as they can damage the natural finish.
Step 2: Gentle Soap Cleaning for Stubborn Dirt
For stains caused by food, footprints, or grease, use a mild soap solution. Mix pH-neutral soap with warm water and scrub gently using a soft brush. Rinse thoroughly afterwards to prevent soap residue.
Tip: Never use acidic cleaners such as vinegar, bleach, or strong chemicals, as they can erode both sandstone and limestone.
Step 3: Removing Algae, Moss, and Lichen
In damp or shaded areas, sandstone and flagstone may develop green patches of algae or moss. To clean:
- Scrub gently with a stiff brush.
- Rinse with warm water and mild soap.
- For recurring growth, use a stone-safe algae remover.
This helps maintain a clean, non-slippery surface, especially on outdoor paving and stepping stones.
Step 4: Pressure Washing (With Care)
A pressure washer can be effective for deep cleaning patios, pathways, or circular stones, but it must be used carefully:
- Always choose the lowest pressure setting.
- Hold the nozzle at a safe distance to avoid surface damage.
- Avoid using it on delicate, hand-cut stones.
Limit this method to once or twice a year.
Step 5: Sealing Sandstone for Extra Protection
Applying a sealant is one of the best ways to extend the life of sandstone, limestone, or flagstone. A breathable sealant prevents water absorption, algae growth, and staining.
- Apply sealant after installation.
- ARe-seal every 3–5 years, depending on usage.
- Choose colour-enhancing sealants for outdoor areas to preserve the vibrancy of the stone.
Step 6: Stain Removal Techniques
Even with sealing, stains may occur. Here’s how to handle them:
- Food and drink stains: Clean with mild soap and water.
- Oil stains: Apply baking soda paste, leave for a few hours, then rinse.
- Rust stains: Use a stone-safe rust remover (avoid acids).
- Organic stains (leaves, plants): Scrub with warm water and a soft brush.
Always test cleaners on a small, hidden area first.
Step 7: Seasonal Maintenance
Outdoor sandstone, limestone, or flagstone installations benefit from seasonal care:
- Summer: Rinse frequently to prevent dust build-up.
- Monsoon: Watch for algae growth and clean promptly.
- Winter: Avoid using de-icing salts directly on sandstone, as they can cause damage.
Preventive Tips for Long-Lasting Beauty
A few simple practices can go a long way:
- Use mats in high-traffic areas to reduce scratches.
- Sweep outdoor paving regularly.
- Wipe up spills immediately to avoid stains.
- Trim overhanging plants to reduce organic staining.
