Polymeric sand is a popular choice for filling the joints between pavers and bricks, providing stability and preventing weed growth. Over time, however, it can wear down or wash away due to weather conditions, heavy rainfall, or improper installation. If you’ve noticed that your polymeric sand needs replacement, this guide will walk you through the process of removal and installing polymeric sand step by step.
Why Replace Polymeric Sand?
Before diving into the removal and replacement process, it’s important to understand why polymeric sand might need to be replaced:
- Washing Away: Heavy rains or improper drainage can wash away sand, leaving joints exposed.
- Cracking or Crumbling: Aging or exposure to harsh weather over the years can cause the sand to break down.
- Weed Growth: If you notice weeds starting to pop up between your pavers, it’s a sign that the sand may no longer be effective.
Step-by-Step Guide to Replacing Polymeric Sand
Step 1: Gather Your Materials
Before you begin, make sure you have the following materials and tools for installing polymeric sand:
- New polymeric sand
- Broom
- Pressure washer or hose
- Jointing tool or trowel
- Safety goggles and gloves
- Wet saw (if needed for cutting pavers)
- Plastic sheet or tarp (to protect surrounding areas)
Step 2: Remove Existing Sand
- Clear the Area: Start by removing any furniture or obstacles from the area you’ll be working on.
- Old Sand Removal: Use a broom to sweep away the existing polymeric sand. If it’s compacted, you may need a jointing tool or trowel to help dislodge it. Make sure to get into the joints thoroughly.
- Dust Precaution: Some old sand may create dust, so wearing a mask can help prevent inhalation.
Step 3: Clean the Joints and Pavers
- Rinse the Area: Use a pressure washer or hose to thoroughly rinse the joints and the surface of the pavers. This helps remove any remaining dust and debris.
- Let it Dry: Allow the area to dry completely before proceeding. Wet surfaces can prevent the polymeric sand installation from setting properly.
Step 4: Apply New Polymeric Sand
- Spread the Sand: Pour the new polymeric sand onto the paver surface. Use a broom to spread it evenly across the pavers, ensuring it fills the joints completely.
- Compact the Sand: Use a jointing tool or a compactor to press the sand into the joints. This step is crucial for achieving a tight fit and ensuring stability in your patio, garden, or other hardscape areas.
Step 5: Activate the Polymeric Sand
- Mist with Water: Once the joints are filled, lightly mist the sand with water using a hose. Be careful not to over-saturate it; a light spray is enough to activate the binding agents in the sand.
- Follow Manufacturer Instructions: Always refer to the specific instructions on your polymeric sand packaging, as activation techniques may vary. We recommend using Gator Maxx G2. Water the sand for 30 seconds per 30 square feet until the water begins to reject, pool, or pond.
Step 6: Allow to Cure
- Let It Set: Allow the polymeric sand to cure according to the manufacturer’s recommendations. This usually takes about 24 hours, but it may vary based on the product and weather conditions.
- Avoid Heavy Traffic: During the curing period, avoid walking on or placing any heavy items on the pavers to ensure proper bonding.
Step 7: Final Clean-Up
- Sweep Excess Sand: Once the curing time is complete, use a broom to sweep away any excess polymeric sand that may be sitting on the surface of the pavers.
- Inspect the Joints: Take a moment to inspect the joints to ensure they’re filled correctly. If you notice any gaps, you can apply more sand as needed.
