1. What is Polymeric Sand?

Polymeric sand is a mixture of fine sands combined with additives that form a binding agent when activated with water. Gray polymeric sand is commonly used between pavers to lock them in place and prevent weed growth while allowing proper drainage.

2. How Does the Calculator Work?

The calculator uses the standard polymeric sand formula:

Where:

• Area — Total area of the paved surface in square feet
• Joint Width — Width between pavers in inches
• Joint Depth — Depth of the joints in inches
• 162 — Conversion factor (cubic inches per pound of sand)

Explanation: The formula calculates the volume of joints in cubic inches and converts it to pounds of sand needed.

3. Importance of Proper Calculation

Details: Accurate calculation ensures you purchase the right amount of polymeric sand - too little won't properly fill joints, while too much is wasteful and can cause hazing on paver surfaces.

4. Using the Calculator

Tips: Measure your paved area accurately. Typical joint widths range from 1/8" to 1/2". Joint depth is usually equal to the paver thickness minus 1/4" to allow for proper compaction.

5. Frequently Asked Questions (FAQ)

Q1: Why use gray polymeric sand?
A: Gray blends well with most paver colors and provides a neutral, natural-looking joint filler.

Q2: How much extra should I buy?
A: It's recommended to purchase 10-15% more than calculated to account for settling and waste.

Q3: Can I use this for different joint sizes?
A: Yes, the formula works for any joint size, but ensure consistent measurements across your project.

Q4: Does temperature affect application?
A: Ideal application temperature is between 50-90°F. Avoid application in extreme heat or if rain is expected within 24 hours.

Q5: How often should polymeric sand be replaced?
A: Properly installed polymeric sand can last 5-10 years before needing replacement, depending on weather and usage.
