One-step weed protection for up to 12 months

Roundup Dual Action 365 Weed & Grass Killer Plus 12 Month Preventer Refill delivers a single, fast-acting solution for non-lawn spaces. This refill supports both killing existing weeds and preventing new growth for up to a full year when used as directed. It targets a wide range of common weeds and grasses, including clover, dandelion, large and smooth crabgrass, poison ivy, and other broadleaf or grassy varieties, plus brush. The formula is designed to work in hardscape areas like cracks and crevices, driveways, sidewalks, patios, paths, and spaces under decks, as well as gravel zones and other non-lawn areas.

Fast-acting performance you can see and feel

Expect rainfast protection in as little as 30 minutes, with visible results in hours depending on weed type and conditions. This gives you the flexibility to plan maintenance around your schedule and weather. While results vary, many users notice improvement soon after application as the product moves from foliage to root systems.

Two clear bulleted lists for quick use and planning

  • What it kills and protects against: clover, dandelion, large and smooth crabgrass, poison ivy, other broadleaf weeds, grassy weeds, and brush.
  • Where and how to apply for best results: treat cracks and crevices in driveways, sidewalks, patios, paths, and under decks; apply to non-lawn areas such as gravel zones; ensure you spray the entire area you want to control, not just emerged weeds.
  • Refill and coverage: pour into an empty container with no added water; one 1.25 gal container covers up to 375 sq ft.
  • Usage tip: for long-lasting control, treat the full area you want to protect and reapply as needed according to label directions.

With its straightforward refill process and targeted action, this Roundup refill makes it easy to keep walkways, driveways, and other non-lawn spaces cleaner for longer—without requiring lawn-specific products. Always follow the product label for application instructions and safety guidelines.
