Grass between patio stones is more than a nuisance—it’s a sign of compromised joint integrity. By sealing your pavers, you create an impermeable barrier that stops regrowth and protects your investment.
Every spring, homeowners confront a relentless invader: grass sprouting between patio stones. Unlike weeds in garden beds, these blades anchor deep into paver joints, resisting simple pulling and threatening the stability of your hardscape. Left unchecked, they root beneath the surface, causing uneven stones and costly repairs.
The definitive answer isn’t more herbicides or endless digging—it’s a proactive sealing strategy. This method eradicates existing growth and prevents future germination by blocking water and seeds from entering the sand joints. Sealing also defends against sun damage, cracking, and stains, effectively extending the life of your patio.
To achieve lasting results, follow this three-phase process grounded in expert landscaping practice.
Essential Tools and Materials
- Narrow weeding tool or flat-head screwdriver
- Scrub brush
- Garden hose with sprayer
- Dish detergent
- Broom
- Penetrating water-based paver sealer
- Sprayer or paint roller
- Optional: Grass-specific herbicide, pressure washer
Phase 1: Eradicate Existing Grass
Start by removing all current growth. For isolated weeds, use a narrow weeding tool like a CobraHead or an old flat-head screwdriver to scrape roots from each crack. Kneel on a cushion to avoid strain and work systematically.
For heavy infestations, apply a herbicide labeled for both grass and broadleaf weeds. Spray on a dry, clear day, wait 48 hours, and reapply if necessary. Hand-pull any survivors, then rake away dead material. Crucially, avoid vinegar; its acidic properties can etch, discolor, and weaken stone and concrete [1].
Phase 2: Prepare the Surface
Thorough cleaning is non-negotiable. Use a low-pressure washer or scrub with soapy water to remove dirt, algae, and mildew. Rinse completely and let the patio dry fully. Next, sweep fresh sand into all gaps and low spots, using a broom to work it deep into joints. Mist lightly to settle the sand, then allow another 24 hours of drying time. Any residual moisture will trap under the sealer and promote new growth.
Phase 3: Apply a Penetrating Sealer
Select a water-based, penetrating sealer formulated for pavers. These products seep into the stone and sand, creating an internal barrier that blocks water and seeds. Apply during a two- to three-day stretch of mild, dry weather. Using a sprayer or roller, coat the surface evenly. Observe the manufacturer’s cure time—typically 24 hours—before walking on or furnishing the patio.
Long-Term Maintenance
Sealing isn’t a one-time fix. Reapply every two to three years, or sooner if you notice wear, discoloration, or new weed sprouts. Porous materials like brick may need more frequent treatment. Incorporate routine sweeping and immediate removal of any new seedlings to maximize longevity.
This process transforms your patio from a constant battle zone into a low-maintenance sanctuary. The initial effort yields years of saved time and preserved beauty.
