Polymeric Sand Calculator
Estimate polymeric jointing sand from paved area and product coverage, then check joint width and depth against the bag coverage table.
Estimate polymeric jointing sand from paved area and product coverage, then check joint width and depth against the bag coverage table. Use finished project dimensions and product-specific data where available rather than generic defaults. The most sensitive assumption here is joint width and depth. Polymeric-sand coverage varies dramatically with the joint geometry. Use the bag's coverage chart for the closest paver size and joint width.
What you need to enter
The Polymeric Sand Calculator uses the following project information to calculate the result.
- Area
- Coverage per unit
- Extra allowance (%)

How the Polymeric Sand Calculator works
Core method: area ÷ coverage × allowance. On the Polymeric Sand Calculator, this relationship is applied specifically to polymeric jointing sand for installed pavers. Compatible measurements are converted to a common internal unit before calculation, then the result is returned in the selected unit system. The main variable to verify is joint width and depth.
Polymeric Sand Calculator worked example
Polymeric Sand Calculator example: If polymeric jointing sand for installed pavers covers 24 m² and the chosen product is rated at 5 m² per unit, a 10% allowance takes the theoretical 4.8 units to 5.28. The buying quantity would therefore be rounded up to the next whole bag, tub or cartridge where applicable. Before relying on that figure, check joint width and depth; the final decision should also follow the actual product or project specification.
Important calculation assumptions
For polymeric jointing sand for installed pavers, polymeric-sand coverage varies dramatically with the joint geometry. Use the bag's coverage chart for the closest paver size and joint width.
Frequently asked questions
How should I collect the measurements for the Polymeric Sand Calculator?
The quality of the result starts with the inputs. Use the measured area plus the exact product coverage. Where joint width, depth or trowel size changes coverage, use the manufacturer table. They are used here to estimate polymeric jointing sand for installed pavers.
How does the Polymeric Sand Calculator use joint width and depth?
A sensible Polymeric Sand Calculator result depends on getting joint width and depth right. Polymeric-sand coverage varies dramatically with the joint geometry. Use the bag's coverage chart for the closest paver size and joint width.
Should I order exactly the amount shown by the Polymeric Sand Calculator?
Use the Polymeric Sand Calculator result with the coverage table for the exact jointing product. Paver size, joint width, joint depth and compaction method can change bag yield substantially, so round only after applying the manufacturer's rate.
