About the product
Microduo Bi-component Microcement Cemher
Microduo is Cemher's traditional microcement: a bi-component lime + Resincem resin system that offers the widest variety of finishes and adapts to almost any surface. It stands out for its easy trowel application thanks to a very long hardening time (more than 5 hours of mixture life), which makes it very user-friendly for both professionals and those new to microcement. Each kit includes the powder and the necessary Resincem resin.
You don't have to buy the resin separately. With more than 5 hours of open time, you can work large surfaces without the mixture drying, correcting textures and blending calmly.
Granulometries and coverage
The granulometry determines the texture and use of each layer. The preparation and coverage data are those of the manufacturer (coverage per layer; a complete system usually involves two base layers and two finish layers).
| Granulometry | Recommended use | Preparation | Coverage/layer |
| Fine | Ultra fine. Vertical surfaces, stucco effect. CT-C30-F9. Only as a finish. | 10 kg + 5 L of Resincem | 0.5 kg/m² |
| Medium | Medium. Horizontal and vertical, medium traffic, no stucco. CT-C40-F10. Only as a finish. | 20 kg + 8 L of Resincem | 0.6 kg/m² |
| Base | Coarse, non-slip. Horizontal and vertical, high traffic. CT-C40-F10. Base and finish. | 20 kg + 5 L of Resincem | 1 kg/m² |
