About the product
Microdur Cemher Single-Component Microcement
Microdur is Cemher's single-component microcement: it mixes only with water, with no resins to dose. Formulated with high-performance cements, aggregates, additives, and synthetic resins, it simplifies mixing and application compared to resin systems (Microduo), and its faster hardening shortens project timelines. It does not crack, has compensated shrinkage, good UV resistance, and is applied in thicknesses of 0.3 to 5.5 mm on floors, walls, ceilings, furniture, countertops, and radiant heating floors, indoors and outdoors.
Open the bag, add the indicated amount of water with the already dissolved Cemher Toner, mix for 2 minutes at low revolutions, and apply. Fewer components to buy, transport, and control on site. Classified C40 according to UNE-EN 13813 and CE marked.
Granulometries and yields
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 layers and two finishing layers).
| Granulometry | Recommended use | Preparation | Yield/layer |
| Fine | Ultra fine. Vertical surfaces, stucco effect. For finishing only. | 10 kg + 4 L water | 0.5 kg/m² |
| Regular | Fine. Horizontal and vertical, light stucco effect. For finishing only. | 10 kg + 4 L water | 0.5 kg/m² |
| Medium | Medium. Horizontal and vertical, medium traffic, no stucco. For finishing only. | 20 kg + 6.5 L water | 0.6 kg/m² |
| Base | Coarse, non-slip. High traffic. Preparation and finishing layer. | 20 kg + 5 L water | 1 kg/m² |
| Coarse Base | Ultra coarse, non-slip, and extremely hard. High traffic and substrates with wide joints. Preparation and finishing. | 20 kg + 5 L water | 1.5 kg/m² |
Why choose Microdur
- ✅ Single-component — cement + water, no separate resin.
- ✅ C40 resistance — > 40 N/mm² compression, SH 200 surface hardness, and > 4 N/mm² adhesion (B 4.0).
- ✅ Does not crack — compensated shrinkage and high tenacity; thicknesses from 0.3 to 5.5 mm.
- ✅ Non-slip and safe — USRV 41 · Class 2 (CTE); fire reaction A1 / A1FL; indoor air emissions A+.
- ✅ Suitable for radiant heating floors and furniture with wheels — breathable with excellent adhesion to mineral substrates and old tiles.
Recommended application system
- Preparation: clean, grease-free, consolidated, and flat substrate. On tiles or non-porous surfaces, Puente de Unión 100; fiberglass mesh where there is a risk of cracking.

- Preparation layers: two layers of Base or Coarse Base with a metal trowel; sand with 40-grit sandpaper between layers.
- Finishing layers: two layers of Fine, Regular, or Medium with a rubber trowel, "wet on wet" or "wet on dry" (≈ 3 h between layers); sand with 220-grit sandpaper.
- Sealing after 24–48 h with humidity < 5%: pore-filler primer and Aquamax varnish (water-based) or Maxipur (solvent-based).
• Cemher Microcement Effect Toner (125 / 250 / 500 ml) for coloring.
• Puente de Unión 100 for application on tile, marble, or non-porous surfaces.
