The fastest way to deal with weeds between pavers is to pull or scrape what’s growing now, then rebuild the joints with polymeric sand so new seeds can’t take hold. That two-part approach — remove, then reset — beats any single spray or home remedy because it fixes the actual problem: loose, organic-rich joint sand that acts like a planter box for windblown seeds.

Here’s the quick version:

  1. Kill what’s there — hand-pull, scrape, or spot-treat before weeds flower and drop seed.
  2. Rebuild the joints — strip old sand, dry the joints, and install polymeric sand.
  3. Maintain seasonally — sweep, spot-check, and reseal so the cycle doesn’t restart.

Treat this as ongoing management, not a one-time fix. Even a flawless installation will need occasional touch-ups, and if weeds keep pushing through fresh sand, you may be looking at a drainage or base issue worth a professional look.

Pro Tip: Catch weeds before they flower. A weed that never sets seed can’t reinfest your joints next spring, and that alone cuts your workload dramatically.

How to Get Rid of Weeds Between Pavers Right Now

Start with the lowest-effort option and work up. Most paver weeds are shallow-rooted annuals, so hand-pulling and joint scraping handle the majority of cases without any product at all.

Fast wins (5 to 10 minutes per patch):

  • Hand-pull weeds after a rain, when soil is soft and roots come out whole.
  • Scrape joints with a flathead screwdriver, hori-hori knife, or purpose-built joint weeder.
  • Wear gloves and eye protection, especially around brick edges that chip.

Household methods work, but with real limits. Boiling water scalds top growth on contact and is safe around pavers, though it rarely kills deep taproots. A vinegar-and-dish-soap mix (the soap breaks surface tension so the acid clings to leaves) does similar damage to foliage but can also harm nearby ornamentals and soil microbes if you overuse it. Baking soda and salt are the riskiest of the bunch: both raise soil salinity, and repeated applications can sterilize the joint or leach into surrounding beds. The University of Illinois Extension flags all of these as non-selective, meaning they don’t distinguish weeds from your hostas.

Mechanical and heat options step things up. A pressure washer on a fan-tip nozzle can blast small weeds and grime out of joints, but hold it at an angle and moderate distance. Too much pressure strips the joint sand along with the weed, which just invites the next seed in. Propane flame weeders scorch foliage fast but demand real caution near mulch, dry grass, or wood fencing.

Chemical options make sense for stubborn perennial weeds or larger areas. Glyphosate remains the most common non-selective herbicide sold for this purpose, and it’s worth understanding what it is before you spray. Glyphosate works by disrupting a plant enzyme pathway, but it doesn’t discriminate between weeds and desirable plants, so drift onto lawn or garden beds is a real risk. Follow the label exactly, apply on a calm, dry day, and keep pets and kids off the area until it’s dried.

Fix the Joints So Weeds Stop Coming Back

Most weeds between pavers start as seeds that blow or wash into loose joint sand, then germinate in the organic debris that collects there over time. That’s why joint quality matters more than any single removal method. Polymeric sand hardens into a firm, semi-flexible bond that resists both washout and seed germination, unlike plain mason sand, which stays loose enough for roots to settle in.

Resetting joints, step by step:

  1. Remove old, degraded sand with a stiff brush, joint tool, or low-pressure washer.
  2. Let joints dry completely. Wet joints prevent proper polymeric sand activation.
  3. Sweep in new polymeric sand, working it fully into the joint with a compactor or hand tamper.
  4. Mist with water per the manufacturer’s activation instructions. Too much water washes the polymer out; too little leaves it chalky.
  5. Keep foot traffic off the area until fully cured, usually 24 hours.

A sealer applied over cured joints adds another layer of protection against moisture and seed lodging, and most manufacturers recommend resealing every 2 to 3 years depending on sun and traffic exposure.

Common mistakes:

  • Skipping the drying step before applying sand.
  • Overwatering during activation, which leaves haze or washes the binder away.
  • Sanding over heavily infested joints without removing roots first.

Pro Tip: Test polymeric sand on one small section before doing the whole patio. Climate and paver type both affect cure time, and a test patch saves you from redoing a full driveway.

When Weeds Signal a Bigger Paver Problem

Sometimes weeds aren’t a joint issue at all. If you’re pulling grass out of the same spots every few weeks, or pavers feel like they’re rocking or sinking underfoot, the problem is likely below the surface.

Watch for:

  • Wide colonies of grass or weeds spreading across multiple joints, not isolated sprouts.
  • Pavers that shift, lift, or feel uneven when you walk across them.
  • Standing water or damp patches that linger long after rain.
  • Weeds returning within days of a fresh resand.

These patterns usually point to a compromised subbase, poor compaction, incorrect slope, or landscape fabric installed under the pavers instead of a proper aggregate base. Unilock notes that ponding water in particular creates ideal weed habitat and often traces back to drainage that was never corrected during installation. Fixing that usually means pulling the affected pavers, rebuilding the base, and correcting slope before any new sand goes in.

Pro Tip: Before spending money on repeated resanding, check whether water pools on the surface after rain. If it does, you’re treating a symptom, not the cause.

Building a Weed Prevention Routine That Actually Works

A simple seasonal rhythm keeps weeds from reestablishing once you’ve reset the joints. Skip this step and you’ll be back to hand-pulling within a season.

Maintenance schedule:

  1. Sweep or blow debris off pavers weekly during high-pollen and leaf-drop seasons.
  2. Spot-check joints monthly for early sprouts and pull them before they flower.
  3. Rinse with a gentle pressure wash twice a year, avoiding a setting strong enough to strip sand.
  4. Inspect after major storms for washout or shifting.
  5. Reseal joints every 2 to 3 years alongside a fresh polymeric sand top-up where needed.

Cleaning notes: a stiff broom and leaf blower handle most debris without disturbing joint sand. Save the pressure washer for stubborn grime, and keep the nozzle wide and the distance generous.

For wide joints or low-traffic paths, a living groundcover can outcompete weeds entirely. Sedum, Corsican mint, and bugleweed all tolerate light foot traffic and fill space weeds would otherwise claim, though it’s worth checking hardiness for your region before planting.

Pro Tip: Pair polymeric sand with regular sweeping and periodic sealing. Each piece covers a gap the others miss, and together they outlast any single fix.

When to Call a Professional Paver Contractor

Call a pro when weeds keep returning within weeks of a resand, when pavers noticeably shift or rock, or when you’re seeing standing water after every rain. Those are base and drainage problems, not joint problems, and DIY resanding won’t fix them.

Ask a contractor:

  1. What’s the current subbase depth and compaction, and does it meet local standards?
  2. Is the slope correct for drainage, and would it need regrading?
  3. How much experience do they have installing and activating polymeric sand?

Budget differs sharply between a joint reset and a full base rebuild, so get more than one estimate before committing. A solid inspection should include photos of the current condition and a written scope, plus some warranty on the completed work.

An installer’s take on realistic weed control

Permanent weed-proofing is a myth we hear about constantly, and it’s the wrong goal to chase. The realistic target is management: a stable base, tight joints, and moisture that drains instead of sitting. Get those three right, and weeds stop being a weekly chore.

Budget for occasional re-sanding and resealing as routine upkeep, not a sign something failed. Even a well-installed patio needs joint attention every few years, and gardening professionals agree that catching growth early beats any promise of a permanent solution.

  • Correct base and compaction first.
  • Joint stability second.
  • Moisture control third.

Our take on long-term paver care

We’d rather see homeowners invest in a proper base and polymeric sand than chase every new spray on the shelf. It’s the difference between a patio that needs light upkeep for years and one that reopens the same fight every spring. If you want the process explained in more detail, our guide on cleaning and sealing patio pavers walks through it, and yes, we do account for Texas heat and clay soil when we spec materials.

FAQ

How do you permanently get rid of weeds between pavers?

There’s no truly permanent fix, but rebuilding joints with properly activated polymeric sand and removing weeds before they seed comes closest to lasting results.

What’s the best way to remove weeds already growing between pavers?

Hand-pull or scrape them out roots and all, then treat any remaining growth with boiling water or a labeled herbicide before resanding the joint.

What’s the best product to kill weeds between pavers?

For localized, stubborn weeds, a labeled glyphosate product applied per instructions is among the most reliable chemical options, but always weigh it against household methods for smaller patches first.

What can you put between pavers to stop weeds?

Polymeric sand is the standard answer, since it hardens into a joint that resists both seed germination and washout better than loose sand.

When should I call a professional instead of fixing joints myself?

Call a contractor if pavers shift, water pools after rain, or weeds return within weeks of resanding, since those signs usually mean a base or drainage problem beyond a DIY fix.
