MORTAR MIX Quick Repair Mortar

Application

MORTAR MIX is a multifunctional quick-repair mortar suitable for concrete repair, stucco and plaster repair, single-layer exterior plaster, levelling layers, formwork work and for the repair of roadways. Can be used indoors and outdoors, even in wet areas. MORTAR MIX can be processed horizontally, vertically and overhead.

Sustainable construction

The use of MORTAR MIX reduces the CO2 footprint, increases energy and resource efficiency and conserves natural resources. The production of Rapid Set cement requires 30% less CO2 emissions than conventional Portland cement. For further information (e.g. LEED values) contact KORODUR Contact

Properties

In the case of high grinding wear, MORTAR MIX is also available in the quality MORTAR MIX SVS 5 with wear carrier in accordance with DIN 1100 Group A (KORODUR VS 0/5) for floor renovations > 15 mm on request.

• Substrate: Clean the substrate, remove loose components, cement sludge, dust, acids, oil and grease. For a force-fit composite, the surface must be crack-free, even, rough and open-pored. The surface tensile strengths required in the regulations must be observed (1 N/mm2 must not be less than 1 N/mm2). Before processing, the substrate must be thoroughly pre-wetted. In the case of highly absorbent surfaces, pre-wetting may have to be repeated several times*. A film of water or puddles should be avoided. * If necessary, an acrylate-based primer must be integrated.

• Processing: Sufficient personnel and suitable equipment or tools should be available before the work begins. Mix MOTAR MIX with the specified amount of water for approx. 1 - 3 minutes in a suitable forced mixer or agitator, depending on the type of processing. To mix, first add water to the mixing container. Then add MOTAR MIX with the mixer or stirring whisk running. If less water is added, the strengths increase, whereby the maximum water addition must NOT be exceeded. MOTAR MIX can be processed using conventional methods. Finishing should be done as soon as possible. MOTAR MIX can be smoothed, grated or textured. Installation should be carried out in a complete layer, i.e. not in layers and as evenly as possible. No installation on frozen surfaces. During compaction, air voids should be prevented as far as possible. At temperatures > 20 °C, the processing time is shortened, at temperatures < 20 °C, the development of strength can be delayed. To extend the processing time, Rapid Set SET CONTROL (retardant) or Rapid Set FLOW CONTROL (plasticizer) for increased flowability, as well as the additive FAST to accelerate the setting time, can be added (see CONCRETE PHARMACY data sheet).

After-treatment

with water must be carried out immediately as soon as the surface has lost its damp shine and should be carried out repeatedly within one hour until the product has reached sufficient strength. If longer setting times occur, if temperatures are too low or if a retardant agent is used, longer post-treatment times may be necessary.
