1. What is Techniseal EZ Sand?

Techniseal EZ Sand is a high-quality polymeric sand used for filling joints between pavers. It hardens when wet to prevent weed growth and insect infestation while allowing for proper drainage.

2. How Does the Calculator Work?

The calculator uses the following formula:

Where:

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

Explanation: The formula calculates the volume of joint space and converts it to pounds of sand needed based on standard density.

3. Importance of Proper Sand Calculation

Details: Accurate sand calculation ensures proper joint filling, prevents waste, and helps maintain the integrity of your paver installation. Too little sand leads to joint failure, while too much is wasteful and costly.

4. Using the Calculator

Tips: Measure your project area accurately. Typical joint widths range from 1/8" to 1/2". Joint depth is usually equal to the thickness of your pavers minus any bedding layer.

5. Frequently Asked Questions (FAQ)

Q1: What's the typical coverage rate for EZ Sand?
A: Coverage varies by joint size, but generally 1 lb covers 1-4 ft² depending on joint dimensions.

Q2: Should I round up my sand quantity?
A: Yes, it's recommended to add 5-10% extra to account for compaction and spillage.

Q3: How does joint width affect sand quantity?
A: Sand needs increase exponentially with joint width - doubling joint width more than doubles sand required.

Q4: Can I use this for irregular patterns?
A: Yes, but measure average joint width for best results. For very irregular patterns, add 15% extra.

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