Comparison
Polymeric Sand vs Joint Sand
Conventional joint sand is cheap, easy to top up, and lets the field breathe. Polymeric sand hardens when wetted, so it resists washout, weeds and ants — but it costs more, demands exact installation and cleanup, and must never be used in permeable joints.
Polymeric sand
- —Resists washout on slopes and pressure washing
- —Limits weeds and insect activity
- —Requires precise activation and cleanup
- —Never for permeable systems
Conventional joint sand
- —Lowest cost, simple top-up
- —Forgiving to install
- —Can wash out on slopes or with heavy hosing
- —Weeds germinate in surface debris
Side by side
| Criterion | Polymeric sand | Conventional joint sand |
|---|---|---|
| Washout resistance | High | Moderate |
| Weeds | Reduced | Possible |
| Install risk | Haze if cleaned incorrectly | Low |
| Permeable systems | Not allowed | Use open-graded joint stone instead |
The verdict
Use polymeric sand on slopes, pool decks and surfaces that get pressure washed. Use conventional sand elsewhere — and open-graded joint stone in any permeable assembly.
Frequently asked
- Can polymeric sand be used with permeable pavers?
- No. It seals the joints and defeats the infiltration the system exists to provide; use clean angular joint stone.
