1. What Is HP Nextgel Jointing Sand?

HP Nextgel is a high-performance polymeric jointing sand used for filling paver joints. It hardens when wet to prevent weed growth and insect infestation while allowing for proper drainage.

2. How the Calculator Works

The calculator uses the standard polymeric sand formula:

\[ \text{Sand Needed (lbs)} = \frac{\text{Area} \times \text{Joint Width} \times \text{Joint Depth}}{12} \times 1.65 \]

Where:

\( Area \) — Paving area in square feet
\( Joint Width \) — Width between pavers in inches
\( Joint Depth \) — Depth of joints in inches
1.65 — Conversion factor (lbs per linear foot of 1"x1" joint)

3. Importance of Proper Calculation

Details: Accurate calculation ensures you purchase the right amount of material - too little means incomplete coverage, too much means wasted money.

4. How to Use This Calculator

Tips: Measure your paved area accurately. Typical joint widths are 1/4" to 1/2". Joint depth is usually equal to paver thickness minus 1/2".
