How to Apply Polymeric Sand to Interlock Pavers
Interlock pavers are a popular choice for outdoor paving due to their versatility, durability, and aesthetic appeal. To ensure that your interlock paver installation remains stable and looks its best, applying polymeric sand is a crucial step. Polymeric sand is a specialized sand that binds together the joints between pavers, preventing weeds, dirt, and water from infiltrating the gaps. In this article, we will guide you through the process of how to apply polymeric sand to interlock pavers, ensuring a long-lasting and attractive paving surface.
Materials Needed
Before you begin, gather the following materials:
– Polymeric sand
– A stiff-bristled push broom
– A garden hose
– A trowel or a flat-edged tool
– A bucket or wheelbarrow
– A leaf blower or a broom
Preparation
1. Clean the pavers: Start by sweeping away any debris, leaves, or dirt from the paver surface. This will ensure that the polymeric sand adheres properly to the pavers.
2. Check the weather: Apply polymeric sand on a dry day with no rain forecasted for at least 24 hours. This will allow the sand to set and bind effectively.
3. Mix the polymeric sand: Follow the manufacturer’s instructions for mixing the polymeric sand with water. Typically, you will need to mix one part sand with approximately two parts water to create a slurry.
Application Process
1. Apply the slurry: Using a trowel or a flat-edged tool, spread the polymeric sand slurry over the paver joints. Ensure that the slurry fills the gaps completely, but avoid over-applying, as excess sand can wash away or settle unevenly.
2. Brush the sand into the joints: Use a stiff-bristled push broom to brush the polymeric sand into the joints. This will help to remove any excess sand from the paver surface and ensure that the sand is evenly distributed in the gaps.
3. Remove excess sand: After brushing, use a leaf blower or a broom to remove any excess polymeric sand from the paver surface. This will prevent the sand from washing away or settling unevenly.
4. Water the pavers: Lightly water the pavers to activate the polymeric sand. This will help the sand to bind and harden in the joints. Ensure that the water does not wash away the sand from the joints.
5. Wait for the sand to set: Allow the polymeric sand to set for at least 24 hours before walking on the pavers. This will ensure that the sand has had enough time to bind and harden properly.
6. Clean the pavers: Once the polymeric sand has set, sweep the pavers to remove any remaining debris or dirt.
By following these steps, you can successfully apply polymeric sand to your interlock pavers, ensuring a stable and attractive paving surface that will last for years to come.
