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 to fill the joints between pavers, creating a durable, stable surface that resists erosion and weed growth.

2. How Coverage is Calculated

Coverage depends primarily on joint width:

Where coverage per bag varies by joint width:

• Small joints (1/8 inch): 75-100 ft² per 50 lb bag
• Medium joints (1/4-3/8 inch): 30-60 ft² per 50 lb bag
• Wide joints (over 3/8 inch): 20-40 ft² per 50 lb bag

Note: The calculator uses conservative estimates to ensure you don't run short.

3. Importance of Proper Coverage

Details: Using the right amount of polymeric sand ensures proper joint filling, which prevents weed growth, insect infestation, and paver movement while allowing for proper drainage.

4. Using the Calculator

Tips: Measure your total paved area in square feet and the average width of your paver joints in inches. The calculator will estimate how many 50 lb bags you'll need.

5. Frequently Asked Questions (FAQ)

Q1: Why does joint width affect coverage so much?
A: Wider joints require more sand to fill the same area because there's more empty space between pavers.

Q2: Should I round up when ordering sand?
A: Yes, it's better to have a little extra than to run short mid-project. The calculator automatically rounds up.

Q3: Does paver pattern affect coverage?
A: Yes, patterns with more joints (like herringbone) will use more sand than those with fewer joints (like large-format pavers).

Q4: Can I use this for different bag sizes?
A: The calculator is for standard 50 lb bags. For other sizes, adjust proportionally (e.g., half the bags for 25 lb bags).

Q5: What if my joints vary in width?
A: Use the average width or the widest measurement to ensure you have enough sand.
