How to Remove Polymeric Sand
Polymeric sand, also known as polymeric concrete sand or polymeric bedding sand, is a popular choice for laying pavers due to its ability to prevent water from seeping beneath the pavers, thereby minimizing the risk of weed growth and soil erosion. However, over time, the polymeric sand may need to be removed for various reasons, such as repairs, re-laying, or a complete overhaul of the paver installation. In this article, we will discuss the steps and methods on how to effectively remove polymeric sand from your paver project.
Step 1: Prepare the Area
Before you begin the removal process, it is crucial to prepare the area. Start by clearing the pavers of any debris, leaves, or other foreign objects. Next, remove any plants or grass growing around the pavers, as they can interfere with the removal process. If necessary, use a herbicide to kill the grass roots and ensure they do not regrow after the sand is removed.
Step 2: Apply a Concrete or Masonry Remover
To break down the polymeric sand, apply a concrete or masonry remover to the affected area. Follow the manufacturer’s instructions for the proper application and allow the remover to sit for the recommended duration. This solution will help to soften the polymeric sand, making it easier to remove.
Step 3: Use a Pressure Washer
Once the polymeric sand has been softened, use a pressure washer to blast away the sand. Ensure that the pressure washer is set to a low-pressure setting to avoid damaging the pavers. Start from one end of the affected area and work your way across, paying close attention to the corners and edges where the sand may be more firmly packed.
Step 4: Sweep and Collect Debris
After using the pressure washer, sweep the area to collect any remaining polymeric sand and debris. This can be done with a stiff-bristled broom or a leaf blower. Be sure to dispose of the debris properly, as it may contain hazardous chemicals.
Step 5: Clean the Pavers
Once the polymeric sand has been removed, it is essential to clean the pavers thoroughly. Use a stiff-bristled brush and a suitable cleaning solution to remove any dirt, grime, or stains. Rinse the pavers with water and allow them to dry completely before proceeding with the next steps.
Step 6: Re-lay the Pavers (if necessary)
If you need to re-lay the pavers after removing the polymeric sand, follow the manufacturer’s instructions for laying new pavers. Ensure that the base is properly prepared and compacted before laying the pavers. Apply a fresh layer of polymeric sand, and use a tamper or roller to pack it into the gaps between the pavers.
Conclusion
Removing polymeric sand from pavers can be a challenging task, but with the right tools and techniques, it can be done effectively. By following these steps, you can ensure a successful removal and prepare your paver project for a fresh start. Always remember to take proper safety precautions when working with chemicals and machinery, and consult a professional if you are unsure about any aspect of the process.
