MR. JO Inject – VL : Very Low Viscosity Epoxy Injection Grout for Fine Cracks and Precision Repairs
MR. JO Inject – VL : Very Low Viscosity Epoxy Injection Grout for Fine Cracks and Precision Repairs
MR. JO Inject – VL is a specially formulated, two-component very low viscosity epoxy grout engineered for hairline crack repairs, micro-void sealing, and structural rehabilitation. This solvent-free system penetrates the finest of cracks, flows deeply into concrete capillaries, and forms a chemically bonded, watertight seal.
Its quick-curing properties and exceptional flowability make it ideal for structural applications where early strength, durability, and deep penetration are essential.
🔍 Key Features
✅Ultra-Thin Flow – Penetrates hairline cracks (<0.3 mm) with ease
✅Solvent-Free – No shrinkage or harmful vapors
✅Fast Reactivity – Cures quickly for urgent repairs
✅High Bond Strength – Long-lasting concrete restoration
✅Ideal for Precision Injection – Excellent for grouting under low pressure

🛠️ Applications
- Fine hairline cracks in beams, columns, slabs, RCC tanks
- Grouting of tight structural voids and capillaries
- Injection of wall, slab, or column cracks <0.3 mm wide
- Sealing cracks that can lead to moisture ingress
- Structural repairs in sensitive environments or precision components
💡 When to Choose MR. JO Inject – VL
When cracks are too fine for LV or MV grouts, Inject – VL is the ideal solution. It’s especially useful in:
- Water-retaining structures (like tanks or sumps)
- Fine cracking in factory floors, foundations, or walls
- Architectural concrete where aesthetics matter
- Cases demanding deep penetration without surface flooding
⚠️ Precautions
- Ensure crack surfaces are dry and free of oil/grease
- Do not apply over actively leaking cracks—use sealing grout first
- Wear gloves and avoid skin contact with mixed product
- Clean tools with an epoxy-safe cleaner immediately after use
- Cure time depends on ambient temperature – do not disturb the surface until fully set
🧰 Typical Use Case
A concrete water tank wall develops a network of fine hairline cracks that could lead to seepage. Conventional grouts can’t reach or seal them. Inject – VL flows into even the narrowest cracks, bonds deeply, and restores watertightness and integrity—without demolishing a single tile.
🔄 System Recommendations
- Use MR. JO Inject – MV for wider cracks (0.5–3 mm)
- Use MR. JO Inject – UPS for damp or moisture-laden conditions
VL can also serve as a base treatment before applying coatings in sensitive infrastructure (like pharma or food units)
MR. JO Inject – VL is your trusted solution for precision structural repairs, hairline crack injections, and tight space grouting. With ultra-low viscosity, high strength, and excellent penetration, it delivers unmatched performance—where it matters most.
