Regular sand is cheaper upfront
Standard jointing sand is the low-cost option. It is easy to install and easy to replace, but it usually washes out faster and allows more weed growth over time.
Polymeric sand costs more but reduces maintenance
Polymeric sand contains binders that harden after activation. That makes it better at resisting washout, weeds, and insect activity in the joints.
Driveways usually benefit more from polymeric sand
Paver driveways see more vibration and water movement than patios. That is one reason driveway projects often justify heavier-duty polymeric sand products.
Regular sand is still useful for simple projects
If the project is temporary, budget-driven, or easy to maintain, regular sand can still be reasonable. Just expect to top up the joints more often.
Use the calculator before buying
The price difference between regular and polymeric sand matters most after you know how many bags the project needs. Use the paver sand calculator to estimate volume and bag count first.
