KEIM Concretal MR 2.0 Concrete Repair Mortar
KEIM Concretal MR 2.0 Concrete Repair Mortar is used for restoration of spalling and decayed concrete. The mixed mortar hardens rapidly without shrinkage or cracking.
Also known as Keim CONCRETAL-MÖRTEL-R and Keim Concrete Repair Mortar.
Best Uses
KEIM Concretal MR 2.0 Concrete Repair Mortar is a single component, polymer modified, cement bound mortar, to be mixed with water. This concrete restoration mortar provides low shrinkage and crack free hardening even when exposed to dynamic loads during application.
- Frost resistant
- Resistant to de-icing salt
- Water impermeable, water vapour permeable
- Elevated carbonation resistance
- Non-flammable to DIN 4101, part 1, building material class A1.
KEIM Concretal MR 2.0 can be used on its own or as part of the KEIM Concrete Repair System.
Application
Remove loose material and old coats mechanically or with a water pressure jet. Mix one 25kg bag of KEIM Concretal MR 2.0 Concrete Repair
Mortar with 3.6 Litres of clean water for at least four minutes using a mechanical mixer until the mix is the consistency of moist earth. Materials can then be applied by trowel onto a pre-wetted surface and struck off to the required finish.
KEIM Concretal MR 2.0 Concrete Repair Mortar can be over-coated with KEIM Fine Finishing Mortar if required. Apply in thicknesses from 0.5 - 50mm. Setting time is 1 day per 1mm layer thickness.
