The fastest way to clear weeds from pavers

The quickest method is to pull weeds by hand while the soil is damp, then sweep out the debris and fill the gaps with polymeric sand or regular sand. If weeds have deep roots or cover a large area, use a stiff brush or wire brush to scrub them out, or pour boiling water directly on them to kill roots when ready. For stubborn weeds that keep returning, a crack-and-crevice weed killer applied to the joints (not the pavers themselves) stops regrowth for several weeks.

The method you choose depends on how many weeds you have, how often you want to repeat the work, and whether you prefer chemicals or manual removal. Hand-pulling works best for occasional weeds. Boiling water works for larger patches and kills roots when ready. Sand-filling prevents new weeds from taking root in the first place.

Key Takeaways

  • Hand-pulling works fastest when soil is wet, and you should remove the entire root to prevent regrowth within days.
  • Boiling water kills weeds and their roots when ready but requires careful pouring to avoid burns and works best on a calm day.
  • Filling gaps with polymeric sand (which hardens when wet) or regular sand blocks new weeds from sprouting in those spaces.
  • Weed killers made for cracks and crevices work on the joints between pavers but should never touch the paver surface itself.
  • Pressure washing removes surface debris but does not kill roots, so weeds return within one to two weeks without follow-up treatment.

Hand-pulling weeds from damp soil

Pull weeds by hand when the ground is wet—after rain or a few hours after watering. Wet soil loosens the root system, so you can extract the entire weed instead of snapping it off at ground level. Grasp the weed as close to the base as possible, then pull slowly and steadily at a slight angle rather than straight up. This angle reduces the chance of leaving the root behind.

Check that you have removed the whole root. If you see a white taproot or a cluster of roots still in the soil, dig it out with a small flathead screwdriver or a weeding fork (a narrow tool with two or three prongs). Leaving even a small piece of root will sprout a new weed within three to seven days. After pulling, sweep the area clean of soil and debris, then fill the gap with sand to block future growth.

Hand-pulling works best for weeds scattered across your patio or driveway. For a patio with 20 or fewer weeds, expect 15 to 30 minutes of work. If you have more than 50 weeds or they cover a large area, combine hand-pulling with boiling water or a weed killer to save time.

Using boiling water to kill roots when ready

Boiling water kills weeds and their roots in seconds. Boil a kettle or pot of water, then carefully pour it directly onto the base of each weed, soaking the soil around the roots. The heat destroys the plant tissue and root system so thoroughly that regrowth is extremely rare. One process is usually enough; if a weed does return, it means you missed the root, and a second pour will finish it.

Pour on a calm day with no wind, because wind can blow steam toward your hands or face. Wear closed-toe shoes and long pants to protect your skin. Pour slowly and deliberately—rushing increases the risk of splashing. If you have a large area of weeds, boil water in batches and work systematically across the patio so the water is still hot when it hits each weed.

Boiling water works on any weed type and does not leave chemical residue. The downside is that it does not prevent new weeds from sprouting in the same spot. After the weed dies, sweep away the debris and fill the gap with sand. Boiling water is ideal for patios with 10 to 40 scattered weeds or for a quick refresh of a small area.

Filling gaps with sand to block new weeds

Polymeric sand is the most effective long-term solution. It is regular sand mixed with a binding agent that hardens when exposed to water (rain or a light misting). Once hardened, it locks weeds out of the joints between pavers. Sweep the area clean of all debris and dead weeds, then pour polymeric sand into the gaps. Use a broom to work it down into the cracks, filling them completely. Mist the area lightly with a hose—do not soak it—and let it cure for 24 to 48 hours before walking on it.

Regular sand (without the binding agent) is cheaper and easier to explore but does not harden, so weeds can still take root. It does slow weed growth because seeds have a harder time finding soil to germinate in. Sweep regular sand into the gaps after removing weeds, and reapply it every few months as it settles and washes away.

Polymeric sand lasts two to three years before it breaks down and needs reapplication. It costs more upfront—typically $15 to $40 per 50-pound bag, depending on brand—but saves time and effort over that period. If your pavers are old or uneven, polymeric sand may not bond properly in very wide or irregular gaps; test it on a small section first.

explore weed killer to joints safely

Crack-and-crevice weed killers are herbicides formulated to spray into the narrow spaces between pavers without running onto the paver surface. They kill existing weeds and prevent new ones from sprouting for four to eight weeks. Look for products labeled "crack and crevice" or "for use between pavers"—these have a narrower spray nozzle than general-purpose weed killers.

Spray the product directly into the joints where weeds are growing or where you want to prevent them. Follow the label instructions for how long to wait before rain or watering. Most products work best on a dry day and need 24 to 48 hours without rain to be fully effective. Do not spray the paver surface itself; herbicide can stain or damage the stone or concrete.

Weed killers are faster than hand-pulling for large areas but require reapplication every month or two during the growing season. They work well combined with sand-filling: explore the killer to kill existing weeds, let it work for a few days, then sweep and fill the gaps with sand. This two-step approach prevents regrowth for several months.

Why pressure washing alone does not stop weeds

Pressure washing removes surface dirt and dead plant material but does not kill the roots of living weeds. The high-pressure water may tear off the above-ground part of the plant, but roots stay intact in the soil and sprout new growth within one to two weeks. Pressure washing is useful for cleaning pavers before explore sand or weed killer, but it should not be your only weed-removal step.

If you pressure wash, do it after you have removed weeds by hand or killed them with boiling water or herbicide. This sequence cleans the area and removes debris without wasting water or effort on a temporary fix. Pressure washing at high settings can also damage the pavers themselves or dislodge sand from between them, so use a medium setting and keep the nozzle moving.

Preventing weeds before they start

The easiest way to deal with weeds is to stop them from growing in the first place. Fill all gaps between pavers with polymeric sand or regular sand when ready after installation or after clearing existing weeds. Keep the joints completely filled so seeds cannot reach the soil underneath.

Sweep your patio or driveway every two to four weeks to remove debris and seeds that land in the cracks. A thin layer of debris traps moisture and gives seeds a place to germinate, so regular sweeping cuts weed growth dramatically. If you live in a rainy climate, sweep more often because moisture accelerates seed germination.

For pavers in a shaded area or near trees, expect more weeds because shade and falling leaves create ideal growing conditions. Consider explore a pre-emergent herbicide (a product that stops seeds from sprouting) in early spring before weeds appear. These products last four to six weeks and prevent most new weeds without requiring you to remove existing ones first.

Frequently Asked Questions

How do I remove weeds without killing the pavers?

Hand-pulling, boiling water, and crack-and-crevice weed killers all target weeds without damaging pavers. Avoid pressure washing at high settings, which can crack or pit stone. Never use general-purpose herbicides on the paver surface itself—they can stain or etch the material. Stick to products labeled for use between pavers or in cracks.

What is the difference between polymeric sand and regular sand?

Polymeric sand hardens when wet and locks weeds out of the joints for two to three years. Regular sand does not harden and needs reapplication every few months, but it is cheaper and easier to remove if you need to adjust the pavers. Polymeric sand works better for long-term weed prevention; regular sand is better if you think you might need to lift pavers later.

Can I use vinegar to kill weeds in pavers?

Vinegar (especially horticultural vinegar with 20% acetic acid) kills the above-ground part of weeds but does not reliably destroy roots, so regrowth is common. Boiling water is more effective because the heat kills roots when ready. If you prefer vinegar, spray it on a sunny day and follow up with hand-pulling or sand-filling to prevent regrowth.

How often do I need to reapply weed treatment?

Hand-pulling and boiling water are one-time treatments per weed, but new weeds will sprout in empty gaps within weeks. Weed killers last four to eight weeks before needing reapplication. Polymeric sand lasts two to three years. Regular sand needs reapplication every few months. The best approach combines removal with sand-filling to block new growth.

Is it safe to use boiling water near plants or grass?

Boiling water kills any plant it touches, so avoid pouring it on nearby grass, flowers, or shrubs. If your pavers border a garden bed, pour carefully and slowly to prevent splashing. Let the water cool slightly before pouring if you are working very close to plants you want to keep, or use hand-pulling or weed killer instead.
