MMA repair mortar vs epoxy.
Boydur® M12 outperforms epoxy systems in rapid-curing industrial floor repair — especially at low temperatures and in time-critical environments.
MMA vs Epoxy — Performance Comparison
✅ Boydur® M12 — MMA Mortar
- Traffic-ready in ~60 minutes at 20°C
- Applies at temperatures down to −10°C
- No downtime for critical operations
- Resistant to thermal cycling & shock
- Year-round indoor & outdoor use
❌ Typical Epoxy System
- Requires 24+ hours to cure
- Fails or becomes brittle below +5°C
- Long operational downtime
- Poor thermal cycling resistance
- Limited to controlled environments
How to apply Boydur® M12.
Five steps to correctly apply Boydur® M12 MMA repair mortar for industrial floor repair, anchoring, or floor topping.
Surface Preparation
Clean the repair area thoroughly. Remove all loose material, dust, oil, and contamination. Surface must be dry and structurally sound. Mechanical preparation — grinding or sandblasting — recommended for best adhesion.
Priming
Apply a compatible MMA primer to the prepared surface. Allow primer to become tacky before applying mortar — typically 10–20 minutes depending on ambient temperature.
Mixing
Add 1.5% Part B catalyst into Part A resin. Mix mechanically for approximately 3 minutes until a homogeneous, flowable mortar is achieved. Do not mix by hand.
Application
Apply mixed mortar within the working time of approximately 25 minutes at 20°C. Spread evenly and compact to required thickness — minimum 4–5 mm for floor repair and topping applications.
Curing
At 20°C, traffic-ready in approximately 60 minutes. At lower temperatures, allow additional curing time. At −10°C, full cure takes approximately 2–3 hours.

Frequently asked questions.
How fast does Boydur M12 cure?
At 20°C, traffic-ready in approximately 60 minutes. Working time ~25 minutes. At −10°C, full cure takes approximately 2–3 hours.
What temperature range can it be applied in?
−10°C to +40°C — suitable for year-round use indoors and outdoors. Unlike epoxy systems that fail below +5°C, MMA maintains performance at sub-zero temperatures.
How is Boydur M12 different from epoxy?
Epoxy requires 24+ hours and fails below +5°C. Boydur M12 cures in ~60 minutes and performs reliably at −10°C with better resistance to thermal cycling and mechanical shock.
What is the minimum application thickness?
Minimum 4–5 mm for floor repair and topping applications. For anchoring, thickness depends on project-specific requirements. Contact Boytorun Kimya for guidance.
Is Boydur M12 suitable for outdoor and airport use?
Yes. UV-resistant, withstands freeze-thaw cycles and wide temperature fluctuations. Used in airports, seaport terminals, bridge decks, and outdoor logistics areas. Reference projects include DHM Adana Airport and Gölcük Naval Shipyard.
What is the shelf life of Boydur M12?
12 months when stored unopened at approximately 20°C in a dry, dark location.
What are the compressive and flexural strength values?
Compressive strength ~34 N/mm², flexural strength ~24 N/mm², ball pressure strength 41 N/mm², elastic modulus 4,350 N/mm², surface hardness Shore D ≥ 75.
