Multifunctional mortar for challenging situations
Rough repair mortar for concrete structural defects
- R3 rated and therefore also suitable for repairing structural elements, high adhesion and compressive strength
- Low tendency to cracking and high PH value ensures corrosion protection of reinforcing steel
- Due to its dimensional stability and good adhesion, it is suitable for large continuous surfaces (e.g.: terrace floors)
- Suitable for heavy duty flooring, e.g. industrial floors
Area of application
- Outdoor: floor + wall + ceiling
- Indoor: floor + wall + ceiling
- For plinth
Heating and cooling area
- Floor + Wall
Processing method
- For hand processing
- Fiber-reinforced PCC (polymer-cement-concrete) mortar suitable for repairing concrete and ferro-concrete structures or precast concrete on vertical, horizontal and walking surfaces in a layer thickness of 10-40 mm. It can be used to ensure adequate concrete coverage and rough leveling of the surface. It can also be used for forklift loads. Its surface must be provided with a wear-resistant coating.

Substrate requirement
The substrate must comply with the applicable standards, must be solid, free of loose particles, free of dust, paint, residues of demoulding agents and efflorescence. It must be sufficiently rough, dry and evenly absorbent. The surface shall not be frozen and water-repellent. The minimum substrate cohesion shall be 1,5 MPa and the concrete quality C 20/25. Coat the exposed and cleaned reinforcement with Cemix protective coating.
Substrate preparation
Apply the adhesive bridge to the surface in a thin layer using a brush or broom. The repair mortar is applied to the wet adhesive bridge (wet on wet) in the required layer thickness using a steel trowel or an aluminum slat. We should always pre-treat only as much surface as we can cover with repair mortar before it dries. If the adhesive bridge dries out, another layer must be applied. If the repair mortar has to be applied in several layers, the following layers must be formed either before the lower layer dries or by using an adhesive bridge.
Preparation of the mixture
Prepare the material by pouring the dry mixture into the prescribed amount of water and mixing it. Use potable water to mix the mixture. Mix using a slow-speed mixer. Mix to a homogeneous, lump-free mixture and leave to rest. Then mix again briefly.

Processing instructions
Contaminated, damaged, decaying and dusty parts must be removed. The reinforcing bars must be exposed to the necessary extent and their surface must be mechanically cleaned of corroded parts. Both steel and concrete surfaces must be pretreated with Kontakt ZE / CT adhesive bridge and rebar passivator.
