Rock Glue Pro Trade Strength

Turn loose gravel, bark or decorative stone into a clean, bonded surface that looks sharp, stays in place, and resists shifting. Flow Rock Glue Pro is a premium water-based stabiliser from FlowChemUK, designed to lock loose materials in place, without the mess, fuss or harsh chemicals.

Available in 750 ml, 2 L, 5 L and 10 L formats to suit small garden jobs all the way up to full-site installations.

Why Rock Glue Pro Stands Out

• Dual-action adhesive & binder: Not just a binder, also acts as a jointing sealer, locking pavers, aggregates and mulch together so your surfaces resist erosion, weed intrusion, and wind displacement.

• Permeable & plant-friendly: Even as it holds surfaces in place, Rock Glue Pro allows water, air and nutrients to pass through to the soil below, ensuring healthy plant growth.

• Ready to use, no mixing required (spray method): Grab the 750 ml or 2 L and spray straight onto dry surface; for larger jobs, use 5 L or 10 L. No fuss, no thinning.

• Strong, flexible bond: Cures to a clear, invisible finish that stays strong under foot traffic, weather, washout and frost.

• Safe & low hazard: According to its Safety Data Sheet, Rock Glue Pro is not classified as hazardous under UK CLP rules. 

When to Use It & When Not to

Use Rock Glue Pro when you want:

• Clean, bonded decorative stone, gravel, or mulch beds

• Stabilised surfaces around patios, pathways, drives, borders

• To prevent aggregate washout on slopes or banks

• A tidy, low-maintenance garden look without loose chips

It’s less ideal when:

• You have heavy structural or vehicular load demands (for roads, drives with cars, etc.)

• You require extreme mechanical strength beyond what a binder can do

• There’s a need for permanent rigid surfacing (e.g. concrete, paving slabs)

In those cases, consider a structural surface (paving, concrete or a proper load-bearing sub-base): Rock Glue Pro is for stabilising loose finishes, not replacing structural surfaces.

Pack Formats & Suggested Uses

For example, a 5 L supply is commonly used for stabilising several square metres of loose stone or mulch. 

How To Apply Rock Glue Pro

1. Shake well before use.

2. First coat (spray option): Apply evenly over dry material (gravel, bark, slate).

3. Rake / loosen slightly to allow the product to reach lower layers.

4. Compact / level using a flat tool to ensure contact.

5. Second coat: Spray again over surface to reinforce bonds.

6. Cure time: Typically 24 hours, avoid rain, moisture, foot traffic until fully cured.

7. Optional top-up: After curing, inspect and spray any loose patches.
