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. It's used for filling joints between pavers, providing stability and preventing weed growth.

2. How Coverage is Calculated

Coverage depends on two main factors:

Joint Width: Narrower joints require less sand per square foot
Application Method: Proper sweeping and compaction affect coverage

Standard Coverage Rates:

Small joints (1/8"): 75-100 sq ft per 50 lb bag
Wide joints (1/4"-3/8"): 30-60 sq ft per 50 lb bag

3. Importance of Proper Coverage

Details: Using the correct amount ensures joints are properly filled without waste. Too little sand leads to unstable pavers, while too much can cause hazing and poor activation.

4. Using the Calculator

Tips: Measure your actual joint width before calculating. Account for 10-15% extra for irregular patterns or spillage. Always round up when purchasing bags.

5. Frequently Asked Questions (FAQ)

Q1: Why does coverage vary so much?
A: Coverage depends on joint depth, compaction, and how thoroughly you sweep sand into joints.

Q2: Can I use this for larger joints?
A: For joints over 3/8", consider polymeric gravel or alternative solutions.

Q3: Does brand affect coverage?
A: Slightly - always check manufacturer specifications for the product you're using.

Q4: How should I store unused sand?
A: Keep in original bag in a dry place. Once opened, use within 6 months.

Q5: Can I use this for irregular stone patterns?
A: Yes, but coverage will be closer to the "wide joint" estimate due to varying joint sizes.
