1. What is Techniseal Polymeric Sand?

Techniseal polymeric sand is a jointing material for pavers that hardens when activated with water, creating a durable, weed-resistant surface. It's designed for joints between ⅛" and ⅜" wide.

2. How Does the Calculator Work?

The calculator uses the following formula:

Where:

• \( \text{Area} \) — Total area of the paved surface in square feet
• \( \text{Joint width} \) — Width between pavers (typically ⅛" to ⅜")
• \( \text{Joint depth} \) — Depth of the joints (typically 1" to 2")
• 144 — Conversion factor (square inches to square feet)
• 100 — Sand density (lb/ft³)

Explanation: The formula calculates the volume of all joints in cubic feet, then converts this to pounds of sand needed based on the density of polymeric sand.

3. Importance of Proper Sand Calculation

Details: Accurate calculation ensures you purchase the right amount of material - too little may leave joints incomplete, while too much is wasteful and expensive.

4. Using the Calculator

Tips: Measure your project area accurately. For joint width, measure several spots and use an average. Typical joint depth equals paver thickness minus any bedding layer.

5. Frequently Asked Questions (FAQ)

Q1: How many square feet does a 50 lb bag cover?
A: Coverage is 75-100 ft² per 50 lb bag for small joints (⅛"). Larger joints (⅜") may only cover 25-40 ft² per bag.

Q2: Can I use this for joints wider than ⅜"?
A: Techniseal recommends their HP (High Performance) product for joints up to 1.5". The calculation method remains the same.

Q3: Should I add extra for waste?
A: It's recommended to add 5-10% extra to account for spillage, uneven joints, or calculation errors.

Q4: How does joint depth affect the calculation?
A: Deeper joints require significantly more sand. A 2" deep joint needs twice as much sand as a 1" deep joint of the same width.

Q5: What if my pavers have irregular shapes?
A: For irregular patterns, calculate based on the average joint width. Complex patterns may require more sand than calculated.
