Coverage depends on joint size far more than patio size. Enter your joints for a realistic bag count.

How it works

Joint share of the surface × joint depth × area. A typical 100 pounds per cubic foot converts that to bags.

Before you order

  • Install only when the forecast and pavers are dry, as the bag directs.
  • Blow all dust off paver faces before you wet it.
  • Follow the manufacturer’s joint width limit.

Common questions

How much area does a 50 lb bag cover?

It varies widely with paver size and joint width, which is why this calculator asks for both.

Can polymeric sand go in wide joints?

Only up to the limit printed on the product. Beyond it, choose a wide-joint product.
