The total paved surface area to fill with jointing sand.
Use the same area as the Paver Calculator.
Check your specific product's coverage rating — this varies with joint width and paver size.
Wider joints or smaller pavers (more total joint length per unit of area) reduce coverage per bag; narrow joints with large pavers increase it. Enter the figure for a 50 lb (22.7 kg) bag — where the answer is counted in 20 kg metric bags, that rate is scaled down to the smaller bag for you.

4 x 50 lb bags
Always check your specific product's coverage chart, since it varies significantly by joint width and paver size — this default assumes a common mid-range residential setup.

How this was calculated
Formula source(s)
- Polymeric sand coverage varies with joint width and paver size, but a 50 lb bag commonly covers roughly 80-100 sq ft (7.4-9.3 m²) for standard residential joint widths; the 20 kg bag sold in metric markets holds about 12% less sand and so covers roughly 6.5-8 m²
Inputs used
- Paved Area
- 320 sq ft
- Coverage per 50 lb (22.7 kg) Bag
- 90 sq ft
Intermediate steps
- Area to fill
- 320 sq ft

What this calculation does not cover
- The bag count is nothing more than your area divided by the coverage rate you enter. Joint width, joint depth and paver size are not inputs — a field of small block pavers with wide joints and a field of large-format slabs with tight joints have wildly different sand demand at the same area, and the coverage figure is the only place that difference can enter.
- No waste allowance is added. The result is the exact number of bags to cover the entered area at the entered rate, rounded up to a whole bag; it does not allow for sand lost while sweeping and blowing off the faces, spillage, or the second fill the joints usually need after they consolidate.
- This is jointing sand only. It does not cover the bedding course under the pavers or the compacted sub-base beneath that, and polymeric sand is not a substitute for either.
- The count assumes the standard bag for your selected unit system — 50 lb in imperial, 20 kg in metric. If your supplier stocks another bag size, or a wide-joint product rated differently, work the total out from the weight rather than reading the bag count straight off.
- Nothing here checks that polymeric sand is right for the joint. Manufacturers set a minimum and maximum joint width, a minimum fill depth below the paver surface, and temperature, dryness and curing conditions for the binder; none of those are inputs, so the calculator will happily return a bag count for a joint the product should not be used in. Permeable paving takes a specified open-graded jointing aggregate instead, not this.

Tools and safety for this job
To lay paving. Generic types, no brands, no prices.
Protection this work requires
- Cutting or grinding concrete, masonry, screed, tile or fibre-cement board releases respirable silica: cut wet or extract at the tool, and wear a P2/N95 respirator at minimum — a nuisance dust mask does not filter it.
- Saws, grinders and breakers run above 85 dB, where hearing damage accumulates and does not recover: defenders or plugs for every cut, not just the long ones.
- Breakers and grinders cause permanent nerve damage: limit continuous trigger time, keep hands warm, and stop if fingers tingle or blanch.
- Boards, blocks and bagged material cause most lasting back injuries on small sites: two people or a lifter for full sheets, and never a bag on one shoulder up a ladder.
