REPAIR MORTAR FINE
Formerly 160 j
Thick-layer finishing repair and sanation mortar for concrete structures.
Simplifies repairs up to 15mm depth: Needs one material only!
- Suitable as a finishing layer in thickness of 2-15 mm.
- R3: >30MPa for statically relevant repairs.
- Exceeds the norm requirements for compressive strengths: Strongly resistant to abrasion.
- Low water absorption: High resistant to frost and chemical de-icing agents.
- Contains plasticizing additives: thixotropic. Ideal for manual repairing work.
- 1,0mm grain size: Creates smooth finishing surfaces.
- Good adhesion to concrete and steel: suitable for repair of concrete, reinforced concrete structures and precast concrete.
- Dimensionally stabile: crack-reducing.
- One-component: Only add water.
Area of application
- Outdoor: floor + wall + ceiling
- Indoor: floor + wall + ceiling
Processing method
- For hand processing
- Fine PCC mortar suitable as a final layer for the repair of concrete and reinforced concrete structures or precast concrete in a layer from 2 to 15 mm.

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
Remove any disturbed, hollow-sounding, dirty or otherwise contaminated concrete and low pH concrete so as not to create micro-cracks in the substrate. Pressure wash the entire surface to be repaired to remove loose particles, dust and dirt, and open the surface completely. Before applying the material, moisten the substrate well by soaking it several times for at least one hour before application. Just before application, remove excess water from the surface of the area to be repaired to achieve a matt concrete appearance.
Preparation of the mixture
Směs připravíte tak, že nejprve smícháte 2/3 suché směsi s plným objemem vody. Míchejte ji 2 min. a poté za stálého míchání přidejte zbývající suchou směs a míchejte 3 min. do požadované konzistence. Smíchejte do homogenní směsi bez hrudek. Směs nechte odpočinout. Poté znovu krátce promíchejte. K míchání použijte pomaloběžný pádlový mixér s maximální rychlostí 800 otáček za minutu. K míchání směsi použijte pitnou vodu nebo vodu odpovídající normě EN 1008.

Processing instructions
Apply the mortar with a stainless steel trowel and smooth the surface. Apply the material in such a way that no air is trapped under the trowel or around the reinforcement. Allow the layer to set before finishing the surface with a foam trowel. Wet the smoother slightly and roll the surface. If a smooth surface is required, polish afterwards. Each subsequent coat (if necessary) should be applied immediately after the previous coat has set. For all types of applications, each coat should be finished with a consistent unbroken surface and protected temporarily from rapid drying (e.g. by covering with PVC sheeting or damp cloth).
