🌟 Key Benefits
✅ High chemical resistance – compatible with aggressive industrial environments
✅ Versatile application – flowable for leveling, tampable for slopes/covings
✅ Excellent substrate adhesion – ensures long service life without delamination
✅ Easy workability – optimized pot life and working time
✅ Strong foundation – supports heavy-duty or anti-corrosive epoxy topcoats
🧰 Application Guide
- Surface Preparation
- Shot-blast or grind concrete for mechanical anchor
- Clean and dry surface, free of oil, laitance, or debris
- Use primer suited to substrate: MR. JO Primer MVC, LVC, or UPS
- Mixing
- Mix resin (Part A) and hardener (Part B) until uniform
- Slowly add quartz filler (Part C) to form desired consistency
- Use low-speed drill with mixing paddle for uniform blend
- Laying the Underlay
- Flowable: Pour and spread using notched trowel or rake; finish with spike roller
- Tampable: Apply using trowel or hand tamper for slopes, vertical edges, or coves
- Curing Schedule
- Tack-free in 6–8 hours at 25°C
- Light foot traffic after 24 hours
- Topcoat application window: 24–48 hours
- Full cure in 7 days
⚠️ Cautions & Tips
- Apply only over properly prepared and primed surfaces
- Ensure consistent mix ratios; do not batch-part small quantities
- Avoid moisture contact during initial curing
- For vertical or curved sections, tampable grade gives better workability
