1. What is Polymeric Sand?

Polysweep polymeric sand is a mixture of fine sands combined with additives that form a binding agent when activated with water. It's used to fill the joints between pavers, creating a durable, weed-resistant surface.

2. How Does the Calculator Work?

The calculator uses the following formula:

Where:

• \( \text{Area} \) — Total paving area in square feet
• \( \text{Joint width} \) — Width between pavers in inches
• \( \text{Joint depth} \) — Depth between pavers in inches
• \( 144 \) — Conversion factor (square inches to square feet)
• \( 100 \) — Density factor (lb/ft³)

Explanation: The equation calculates the volume of joints and converts it to weight based on standard density.

3. Importance of Proper Coverage

Details: Using the correct amount of polymeric sand ensures proper joint filling, prevents weed growth, and maintains the structural integrity of your paved surface.

4. Using the Calculator

Tips: Measure your area accurately in square feet. For joint width and depth, take several measurements and use the average. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: How accurate is this calculator?
A: The calculator provides a good estimate, but actual requirements may vary based on paver pattern, compaction, and waste factors.

Q2: Should I order extra sand?
A: It's recommended to order 10-15% more than calculated to account for variations and spillage.

Q3: What's the standard joint width for pavers?
A: Typically 1/8" to 1/4" (0.125-0.25 in), but always check your specific paver requirements.

Q4: Can I use this for different brands of polymeric sand?
A: Yes, but density may vary slightly between brands (typically 90-110 lb/ft³).

Q5: How should I prepare the area before applying sand?
A: Ensure joints are clean, dry, and free of debris. Pavers should be firmly set in place.
