No Grow Stone Dust For Paving Wide Joints 20kg

No Grow Stone Dust is a premium-grade jointing material specially formulated for filling wide joints in block paving, patios, driveways, and landscaping projects. Unlike conventional jointing sands, this product offers a unique weed inhibition system designed to prevent the growth of weeds between paving joints, significantly reducing maintenance efforts and prolonging the lifespan of your paved surfaces.

It is important to note that No Grow Stone Dust is not a weed killer — it does not eliminate existing weeds. Instead, it acts as a weed inhibitor, creating an environment within the joints that discourages weed germination and growth once all existing weeds have been thoroughly removed prior to application.

The stone dust features a natural grey colour that complements various paving materials and contrasts attractively with traditional sand-coloured block paving. The product also incorporates a polymeric binding agent which activates upon moistening, causing the sand to harden and form a flexible yet durable joint that resists erosion, movement, and weed invasion.

Key Benefits

• Effective Weed Inhibition: Reduces future weed growth by forming a barrier that discourages seed germination and root penetration in paving joints.
• Not a Weed Killer: All existing weeds must be removed before application for optimal results.
• Durable, Flexible Joints: The polymeric binder hardens the stone dust after activation with water, creating joints that can flex slightly under pressure without cracking or crumbling.
• Weather Resistant: The hardened joints resist washout from rain, wind, and everyday wear and tear.
• Wide Joint Compatibility: Specifically designed for wide joint applications where traditional sands may fail or wash away.
• Aesthetic Finish: The natural grey colour enhances the look of patios, driveways, and landscaping areas without detracting from the paving stones' appearance.
• Low Maintenance: Helps keep your paved areas looking neat and weed-free, reducing the need for costly and time-consuming weed control measures.

Ideal Applications

• Block Paving: Perfect for wide joints in residential and commercial block paving projects.
• Patios and Garden Paths: Enhances the appearance and durability of wide jointed patios and outdoor walkways.
• Driveways: Provides strong, weed-resistant joints suitable for vehicle traffic areas.
• Landscaping Projects: Suitable for various landscaping features requiring stable and weed-inhibiting joint material.

How It Works

No Grow Stone Dust contains specially engineered polymeric additives that activate when the product is lightly moistened during installation. This activation causes the sand particles to bind together firmly, locking the joint material in place. This hardened but flexible joint prevents loose sand from being washed out and reduces the space where weeds can take hold.

Application Instructions

1. Remove Existing Weeds: Thoroughly clear all existing weeds, roots, and debris from the paving joints. This step is critical as No Grow will not kill weeds already present.
2. Clean Joints: Sweep or use a pressure washer (if appropriate) to ensure joints are clean and free from dust or loose material. Allow joints to dry completely before proceeding.
3. Apply Stone Dust: Evenly spread the No Grow Stone Dust over the paved surface, brushing it into the joints with a stiff broom until joints are fully filled.
4. Compact Joints: Lightly compact the sand into the joints to ensure no gaps remain.
5. Activate Binding Agent: Mist the area gently with water to activate the polymeric binder. Avoid over-wetting which can wash away the product.
6. Cure Time: Allow joints to dry and harden over 24-48 hours without disturbance for best results. Avoid heavy traffic during this curing period.
7. Maintenance: Regularly inspect joints for any damage or sand loss, replenishing if necessary to maintain joint integrity.

Technical Specifications

Safety & Storage

• Store in a cool, dry place away from moisture before use to prevent premature activation.
• Use gloves and dust masks during application to avoid skin irritation and inhalation of dust particles.
• Keep out of reach of children and pets until fully cured.
• Dispose of empty bags responsibly according to local regulations.
