Enter your Patio Length, Patio Width, Paver Thickness, and Joint Width into the Polymeric Sand Calculator to find exactly how many 50 lb Bags (or 27.5 lb Pails) you'll need, along with your Total Area and Sand Volume Required — so you can buy the right amount without a wasteful second trip to the store.

The amount depends on your patio area, paver thickness, and joint width. Typically, you'll need 1-2 bags of polymeric sand per 100 square feet of paving area.
Both contain polymeric sand, but pails are easier to handle and store. 50 lb bags are more economical for larger projects, while pails are convenient for smaller areas or touch-ups.
Joint width is the gap between pavers. Common widths are 1/8 inch (0.125) for tight joints and 1/4 inch (0.25) for wider joints. Use a ruler or measuring tape for accuracy.
Yes, it's recommended to purchase 10-15% extra sand to account for waste, compaction, and future touch-ups. Our calculator rounds up to ensure you have enough material.
Yes, this calculator works for all paver types including concrete, brick, and natural stone. Just ensure you input the correct paver thickness and joint width for your specific pavers.
Polymeric sand should fill the entire joint depth but stay about 1/8 inch below the paver surface. This prevents sand from washing out while allowing proper activation.
Coverage depends on paver size, joint width, paver thickness, and surface texture. Rougher pavers and wider joints require more sand per square foot.
Installation typically takes 1-2 hours per 100 square feet, including sweeping, compacting, and watering. Allow 24 hours for full curing before heavy use.
