Grano Dust 6mm – 25kg Bags & Bulk Bags

A clean, screened granite fines aggregate (typically 0–6mm) that compacts hard while staying permeable. Ideal as a firm, smooth blinding layer for block paving, porcelain/stone patios, gravel paths and artificial grass.

Pack sizes:

• Grano Dust 25kg – handy bags for small areas and top-ups
• Grano Dust Bulk Bag – great value for larger projects

Coverage (guideline at 50mm depth):

• Bulk bag: ~8m²
• 25kg bag: ~0.25m² (about 500 × 500mm)

Why choose grano dust?

• Locks tight under compaction – angular particles interlock for a stable, even surface.
• Permeable by design – helps surface water drain, reducing puddling and frost heave.
• Consistent finish – screened fines give a smooth, level bed that’s kinder to porcelain edges than coarse aggregates.
• Clean and low-mess – minimal oversized particles; easy to level and screed.

Typical uses

• Blinding/levelling layer over a consolidated sub-base (e.g., Type 1) for block paving or porcelain/stone slabs.
• Artificial grass bases – creates a stable, smooth upper layer before laying membrane and turf.
• Pathways & seating areas – compact, tidy finish that still drains.

Practical note: use MOT Type 1 (or similar) for your primary sub-base, then apply grano dust as the top levelling/blinding layer. It’s not a substitute for the main load-bearing sub-base.

How to lay (quick guide)

1. Prepare sub-base: Install and compact Type 1 to required depth and falls.
2. Add grano dust: Spread to ~30–50mm (projects with porcelain often prefer the cleaner, tighter finish at ~30–40mm).
3. Level & compact: Screed to level, lightly mist if dusty, then compact with a plate compactor.
4. Final checks: Re-screed high spots, keep falls for drainage, then lay slabs/blocks/turf.

How much do I need?

• At 50mm, allow 0.05m³ per m².
• Bulk bag ≈ 8m²; Grano Dust 25kg ≈ 0.25m².
  Add 5–10% for waste, edges and minor level corrections.

Specification

• Material: Crushed granite fines
• Grading: Typically 0–6mm (may vary slightly by source; fines-rich for tight compaction)
• Finish: Clean, screened aggregate
• Permeability: High (when not over-compacted to full closure)
• Applications: Blinding/levelling layer; not a structural sub-base
