EPOMAX-CMT is a thixotropic mortar for walls and floors, based on cement and water-based epoxy resins, offering the following advantages:
- Simlified and affortable application
- High early and final mechanical strength
- Superior bonding to the substrate
- High vapour permeability
- Non-corrosive (safe for the steel reinforcement)
Certified according to EN 1504-3 and classified as a PCC R 4 repair mortar for concrete. CE marked. EPOMAX-CMT is used for:
- repairing,
- smoothing and
- leveling
of concrete walls and floors that will be covered with:
- epoxy coating
- polyurethane coatings
- plastic floorings,
- carpet,
- wooden parquet, etc.
It is also applied when concrete is relatively fresh to create the proper substrate-at least 2 mm thick-for the application of epoxy layers to avoid problems of detachment etc. Also, it is suitable for use as a final layer, at a thickness of up to 3 mm, for smoothing, leveling and increasing surface resistance to mechanical loads in corrosive environments.
Substrate preparation
The surfaces to be treated must be:
- Stable and slightly wet, without standing water.
- Clean, free of materials that prevent bonding, such as dust, loose particles, grease, etc.
EPOMAX-CMT may be applied on relatively fresh concrete. However, the concrete should be at least 3 days old, in order to avoid cracks, due to concrete shrinkage. Before applying EPOMAX-CMT, the surface has to be well dampened with water.
Mixing of EPOMAX-CMT
Components A,B and C are packaged in separate containers at a predetermined mixing ratio. At first, component A must be stirred well in its container. Then, it should be put in a clean container of approx. 30 l. Subsequently, the whole quantity of component B should be added to component A. The two components should be mixed for approx. 30 seconds, with a low speed mixer (300 rpm). It is important to stir the mixture thoroughly near the sides and bottom of the container, to achieve uniform dispersion of the hardener. Finally, component C is added under continuous stirring. Mixing is done with a low-speed mixer and should go on until a fully homogeneous mixture is obtained. No water should be added to the mixture.
Application process
EPOMAX-CMT should be applied at a thickness of up to 3 mm with a trowel or spatula.
