Indian sandstone is a popular choice for outdoor paving due to its durability and attractive appearance. However, like any surface, it requires regular cleaning to maintain its beauty. One common question homeowners have is whether they can use a pressure washer to clean their Indian sandstone paving.
Indian sandstone can be pressure washed , but it is essential to take certain precautions to avoid damaging the surface. When pressure washing Indian sandstone, use a low-pressure setting and a wide spray nozzle to minimize the risk of etching or pitting the stone. It is also crucial to maintain a safe distance between the pressure washer nozzle and the sandstone surface.
How to Pressure Wash Indian Sandstone
- Begin by clearing the area of any furniture, potted plants, or other objects that may obstruct your cleaning process.
- Sweep the surface to remove loose debris, dirt, and leaves.
- Set your pressure washer to a low-pressure setting, ideally between 1200 to 1500 PSI, to prevent damage to the sandstone.
- Choose a wide spray nozzle, such as a 25-degree or 40-degree nozzle, to distribute the water pressure evenly across the surface.
- Maintain a distance of at least 12 inches between the pressure washer nozzle and the sandstone surface while cleaning.
- Work in a systematic pattern, starting from one end of the paved area and moving towards the other, to ensure you don’t miss any spots.
- For stubborn stains or algae growth, use a mild detergent specifically designed for stone surfaces and apply it using a soft-bristled brush before pressure washing.
- Rinse the surface thoroughly with the pressure washer to remove any remaining dirt, debris, or detergent.
- Allow the Indian sandstone to air dry completely.
Tips for Maintaining Indian Sandstone
- Regularly sweep the surface to prevent the buildup of dirt and debris.
- Address spills and stains promptly to avoid permanent discoloration.
- Apply a sealer to protect the sandstone from stains and enhance its color.
- Re-seal the surface every 1-2 years, depending on the level of foot traffic and exposure to the elements.
- Avoid using harsh chemicals or abrasive cleaning tools that can damage the sandstone surface.
When using a pressure washer on Indian sandstone, it is crucial to maintain the proper angle and distance between the nozzle and the surface. Hold the pressure washer nozzle at a 45-degree angle to the sandstone surface, as this allows the water to effectively remove dirt and grime without causing damage. Maintain a consistent distance of 12 to 18 inches between the nozzle and the surface, depending on the pressure setting and nozzle type. Regularly check the distance and adjust as needed to ensure even cleaning and to avoid concentrating too much pressure on one spot, which may lead to etching or pitting of the sandstone. Move the pressure washer in a slow, steady motion, overlapping each pass slightly to ensure thorough coverage. If you encounter stubborn stains, you may need to make additional passes or use a mild detergent, but always exercise caution to prevent damage to the sandstone surface.
By following these guidelines and tips, you can safely pressure wash your Indian sandstone paving and keep it looking beautiful for years to come.
