Microröck Two-Component Epoxy Microcement Cemher
Microröck is Cemher's highest-performing microcement: a two-component epoxy system (ready-to-use aggregate + hardener) that is mass-impermeable, with 80 MPa compressive strength, high tensile strength, and chemical resistance. It is designed for high-traffic and high-humidity areas: commercial premises, professional kitchens, bathrooms, terraces, and swimming pools. It does not crack, fissure, or stain, with excellent adhesion to any substrate. Each kit includes the hardener in the exact proportion.
Twice the resistance of conventional cementitious microcement and suitable for submerged surfaces. Minimal stucco effect: uniform and very clean finish, perfect for the Mineral and Industrial Collections.
Granulometries and Yields
The granulometry determines the texture and use of each layer. Preparation and yield data are from the manufacturer (yield per layer; a complete system usually involves two base coats and two finish coats).
| Granulometry | Recommended Use | Preparation | Yield/Layer |
| Fine | Ultra fine. Horizontal and vertical. Continuous or stucco finish. CT-C40-F10. For finish only. | 10 kg + 1 L Hardener | 0.5 kg/m² |
| Medium | Medium. Horizontal and vertical, medium traffic, no stucco. CT-C40-F10. For finish only. | 10 kg + 1 L Hardener | 0.6 kg/m² |
| Base | Coarse, non-slip. High traffic. CT-C40-F10. Base and finish. | 10 kg + 1 L Hardener | 1 kg/m² |
| Coarse Base | Ultra coarse, non-slip and extremely hard. High traffic. CT-C40-F10. Base and finish. | 10 kg + 1 L Hardener | 1.5 kg/m² |
Why Choose Microröck
- ✅ 80 MPa compressive strength — the hardest in the Cemher range.
- ✅ Mass-impermeable — suitable for bathrooms, showers, exteriors, and swimming pools.
- ✅ Chemical and stain resistance — ideal for kitchens, hospitality, and retail.
- ✅ Does not fissure or crack — high tensile strength.
- ✅ Kit with hardener included — exact 10:1 ratio, no calculations needed.
Recommended Application System
- Preparation: clean, firm, and dry substrate. On tiles, marble, or mosaics, use Puente de Unión 100.
- Mixing: 10 kg of Microröck + 1 L of Hardener (5 kg + 0.5 L), mechanically stirred until homogenized.
- Fiberglass mesh embedded in the first layer of Microröck Base; second layer, sanding and cleaning.
- Two finish coats (Fine or Medium) pigmented with Cemher Toner; fine sanding between coats.
- Sealing: Impripox or Aquasell and two coats of polyurethane varnish Aquamax Extreme / Maxipur 100 % (for swimming pools, consult the specific sealing system).
• Cemher Microcement Effect Toner (125 / 250 / 500 ml) for coloring.
• Puente de Unión 100 for application on tiles, marble, or non-porous surfaces.
• Impripox + Aquamax Extreme or Maxipur 100 % for high-resistance sealing.
• Residential project without extreme demands? Microdur or Microduo are more economical.
