Tampable Power – Heavy-Duty Underlay for Covings, Ramps & 5–8 mm Screeds
When your epoxy floor demands extra thickness, edge protection, or load resilience, Mr. JO Underlay TMP steps up as your trusted base layer. Unlike flowable underlays, TMP is a tampable epoxy screed, designed to be pressed, packed, and built to shape.
Whether you’re shaping a ramp, forming a coving, or building a thick epoxy base layer, TMP offers a tough, dense, and highly durable platform ready for topcoat finishing.
🧱 What Makes TMP Unique?
- Tampable consistency – Designed for compacting and shaping, not self-leveling
- Quartz-loaded formulation – Ensures compressive strength and volume fill
- Versatile thicknesses – Easily builds 5–8 mm or more in one pass
- Edge-friendly – Perfect for covings, wall junctions, and termination zones
- Compatible with Mr. JO topcoat and coating systems
📦 Composition & Mixing
Recommended Mixing Ratio (by weight):
- Part A (Resin): 5 kg
- Part B (Hardener): 2.5 kg
- Part C (Quartz Sand): 32.5 kg
→ Total mix batch: 40 kg
This high-fill blend is designed for tamping with a trowel — ideal for manual or mechanical pressing applications.
🔧 Ideal Applications
- Covings along wall-floor junctions
- Ramps and slope formation
- 5–8 mm base screeds in heavy-duty zones
- Step nosings, terminations & toe walls
- Patch repair of potholes, undulations, and worn-out sections
- Industrial loading bays and transition joints
⚙️ Product Highlights
✅ High Build & Strength – Easily forms thick layers without sag or shrinkage
✅ Manual Finish Control – Can be compacted and shaped using trowels, floats, or hand tools
✅ Crack-bridging Base – Covers undulations, joints, or shallow damage before topcoat
✅ Superior Compatibility – Works seamlessly under all Mr. JO flooring & coating ranges
✅ Moisture-Tolerant Bonding – Pairs well with UPS primer if substrate is damp
🛠️ Application Guidelines
- Surface Preparation
- Clean surface thoroughly; remove laitance, oil, dust
- Mechanically prepare concrete via grinding or shot blasting
- Apply primer: MR. JO Primer-MVC or UPS depending on moisture and substrate condition
- Mixing Process
- Pre-mix Part A & Part B (5 + 2.5 kg) for 1–2 minutes
- Slowly add 32.5 kg of graded quartz sand while stirring
- Mix until uniform, non-lumpy, and workable
- Use within 30–45 minutes depending on ambient temperature
- Application
- Lay mix using trowel or hand scoop
- Tamp with a wooden float or roller for compaction
- Shape edges, corners, and junctions with appropriate trowels
- Smooth top surface for better adhesion with next coat
- Allow 24 hours curing before applying epoxy topcoat
🧩 Compatible Topcoats
- SL Systems – MR. JO Floor SL1, SL2, EcoFloor 1–2 mm
- Protective Coatings – Floorkot-HB, Protectokot CR/CRH
- ESD or Antistatic Finishes – MR. JO Floor-ASL (on request)
- Chemical Zones – Floor CRSL series or Protectokot-CSA
⚠️ Precautions :
- Do not apply below 15°C surface temperature
- Use calibrated quartz fillers (0.1–0.6 mm) for ideal packing
- Avoid over-troweling or working past pot life
- Protect from foot traffic, moisture, or dust during curing
- If temperature is low, warm up components before use
🏗️ Built to Last Where It Matters
MR. JO Underlay TMP isn’t just another layer — it’s the load-bearing core, the ramp former, the coving builder, and the leveling master for heavy-duty epoxy floors.
Use TMP wherever strength, shape, and long-life support matter most.
