Polymeric sand is an essential material for paver installations, providing a strong, durable, and weed-resistant joint filler. Whether you’re working on a patio, walkway, or driveway, choosing the best polymeric sand can make a significant difference in the longevity and stability of your paver project.
In this guide, we will explore what makes a great polymeric sand, the top options available, and how to use it properly for the best results.
1. What Is Polymeric Sand?
Polymeric sand is a specialized sand mixture used to fill the joints between pavers. It contains fine sand and polymer additives, which create a firm, interlocking bond when activated with water.
Unlike regular sand, polymeric sand hardens when wet, preventing issues like:
✔ Weed growth between pavers
✔ Ant infestations
✔ Erosion and shifting of pavers
✔ Water washout during heavy rain
Because of these benefits, polymeric sand is a superior choice for both residential and commercial paver installations.
2. How to Choose the Best Polymeric Sand?
Not all polymeric sands are created equal. Here are key factors to consider when selecting the best polymeric sand for your project:
2.1 Joint Size Compatibility
✔ Narrow Joints (1/8″-1/4″) → Choose a fine-grain polymeric sand.
✔ Wider Joints (Up to 4″) → Opt for coarse-grain polymeric sand for better stability.
2.2 Strength & Durability
✔ High-quality sands contain strong polymer blends that resist cracking and erosion.
✔ Some brands offer extra durability for high-traffic areas.
2.3 Color Options
Polymeric sand is available in various colors to match your pavers, including:
✔ Tan – Ideal for warm-toned pavers
✔ Gray – Complements cool-toned stone
✔ Black & Charcoal – Creates a bold, modern look
2.4 Water Resistance & Drainage
✔ Some polymeric sands are highly water-resistant, making them great for rain-prone areas.
✔ Others allow for better drainage, preventing water buildup and mold growth.
2.5 Ease of Application
✔ Fast-setting sands dry quickly, reducing downtime.
✔ Low-dust formulations make for a cleaner installation.

4. How to Apply Polymeric Sand Correctly
To ensure maximum durability, follow these steps when applying polymeric sand to your pavers.
4.1 Preparation
✔ Ensure pavers are completely dry before applying sand.
✔ Remove any dirt, dust, or debris from joints.
✔ Use a leaf blower to clear excess ptopics.
4.2 Spread the Sand
✔ Pour polymeric sand over the pavers.
✔ Use a broom to sweep the sand into the joints.
✔ Tap the surface lightly with a rubber mallet to settle the sand.
4.3 Remove Excess Sand
✔ Sweep off any remaining sand from the paver surface.
✔ Use a leaf blower on low power to clear fine dust.
4.4 Activate with Water
✔ Use a gentle mist setting on a garden hose.
✔ Wet the surface gradually, avoiding puddles.
✔ Allow the sand to fully cure for 24 hours.
5. Common Mistakes to Avoid
❌ Applying on Wet or Damp Pavers
Polymeric sand requires a dry surface for proper bonding.
❌ Overwatering the Sand
Too much water can wash away the polymers, weakening the bond.
❌ Not Removing Excess Sand Before Wetting
If extra sand is left on the pavers, it can create a hazy residue.
❌ Ignoring Joint Size Recommendations
Using fine-grain sand in wide joints can lead to cracking and shifting.
❌ Walking on Freshly Applied Sand
Avoid stepping on the pavers until the sand has fully hardened.
6. FAQs About Polymeric Sand
6.1 How Long Does Polymeric Sand Last?
With proper installation, polymeric sand can last 5-10 years before needing a refresh.
6.2 Can I Pressure Wash Polymeric Sand?
No, high-pressure washing can erode the joints. Use a gentle setting if necessary.
6.3 Is Polymeric Sand Waterproof?
Some brands are highly water-resistant, while others allow for better drainage.
6.4 Can I Use Regular Sand Instead of Polymeric Sand?
