| MR. JO Bondkot – UPS | 100:50 | 80–100 mins | Medium | Damp / underprepared | Primer for wet substrates, bonding, sealer | Medium liquid | Pale yellow, translucent |
🔧 How to Choose the Right Bondkot?
| If you need… | Go for… | Why? |
| Bonding on vertical or damp surfaces | MR. JO Bondkot –HV | Sag-resistant, bonds under difficult orientation, thick consistency |
| Fast cure bonding for site repairs | MR. JO Bondkot-STD | Short pot life, economical, usable with filler |
| Long pot life for grout, foundation prep | MR. JO Bondkot-MVC | Highly flowable, fills deep cavities, best for old-to-new concrete bond |
| Low viscosity system for screed or sealer | MR. JO Bondkot-LVC | Better pore penetration, easy mixing with fillers |
| Reliable bond on damp or semi-dry surfaces | MR. JO Bondkot-UPS | Moisture-tolerant, versatile primer + adhesive |
Typical Use Areas
| Application | Recommended Grades |
| Old to new concrete bonding | MVC, STD, UPS |
| Precast segment bonding | HV, UPS |
| Crack sealing | STD, LVC, MVC |
| Primer before epoxy coatings | LVC (dry), UPS (damp), STD (quick) |
| Vertical/overhead applications | HV |
| Epoxy grout/foundation repair | MVC |
| Moist concrete / site constraint | UPS |

🔩 Real-World Example Use Cases
| Site Application | Bondkot Used | Why it Worked |
| Segmental precast bridge joint | HV | Vertical, damp surface; thick epoxy holds in place |
| Crack sealing before flooring in a warehouse | STD | Fast cure and good flow into cracks |
| Waterproofing underlayment bonding | UPS | Moisture-tolerant primer helped avoid rework |
| Large area floor bonding | MVC | Long pot life ensured consistent application |
| Screed base coat in chemical plant | LVC | Penetrated fine concrete pores, great filler blend |
🔗 Compatible Systems
- Primers for epoxy floorings – works with MR. JO FloorKot and MR. JO EcoFloor
- Coatings & overlays – pairs well with MR. JO Protectokot and MR. JO Teckot range
- Screeds – combine with MR. JO EcoUnderlay for build-up flooring solutions
