SikaEmaco® N 5200

(former MEmaco N 5200)

Universal, fast setting, polymer modified, fibre reinforced repair and levelling mortar from 3 to 100 mm thickness

SikaEmaco® N 5200 is a universal, one component, polymer modified, fast setting repair, reprofiling and levelling mortar that meets the requirements of class R2 according to EN 1504-3. SikaEmaco® N 5200 is a ready-to-use material that contains sulphate resistant cement (HSR LA), hydraulic binders, well graded sands, carefully selected polymers and fibres to improve physical and application properties. Applied nanotechnology has been used to significantly reduce shrinkage. When mixed with water, it forms a highly thixotropic mortar that can easily be hand or trowel applied in thicknesses from 3 up to 100 mm in one layer.

  • Formulated with nanotechnology to minimise shrinkage and crack tendency.
  • Superb application properties and feel on the trowel.
  • Smooth, creamy but non-slump mortar.
  • Excellent high build capacity - can be applied 80 - 100 mm in horizontal or vertical applications in one layer, or even 70 – 80 mm overhead.
  • Easy to create profiles and corners without formwork.
  • Can be used as cosmetic and patch repair mortar in one.
  • It can be overcoated in only 4 hours (at +20 °C)
  • Good strength development exceeding the requirement of class R2 according to EN 1504-3
  • Low modulus of elasticity.
  • Basically self-curing

Consumption

Consumption

Approx. 1,600 kg powder is needed to prepare 1 m³ of fresh mortar.

One 20 kg bag will yield approximately 12.5 litres of mortar.
Application steps

SUBSTRATE PREPARATION

Concrete must be fully cured, clean and sound to ensure good adhesion. All loose traces of concrete or mortar, dust, grease oil, etc. must be removed.

Damaged or contaminated concrete should be removed to obtain a keyed surface. Non-impact/vibrating cleaning methods, e.g. shot blasting, sandblasting or high-pressure water jetting are recommended. Aggregate should be clearly visible on the surface of the concrete structure after surface preparation.

Cut the edges of the repair vertically to a minimum depth of 3 mm.

If reinforcing steel is visible, clean to a minimum grade of Sa 2 according to ISO 8501-1 / ISO 12944-4. Ensure back of rebar is also clean. Apply 2 coats of SikaEmaco® P 5000 AP on the prepared reinforcement.

The prepared substrate should be pre-soaked, preferably for 24 hours, but at least 2 hours before applying SikaEmaco® N 5200. The surface must be mat-damp, but without standing water.

 

MIXING

Pour the minimum amount of mixing water into a clean vessel. Mixing water needed: 3.5 to 4.0 litres per 20 kg bag depending upon consistency required. Only use clean uncontaminated water.

Add the SikaEmaco® N 5200 powder rapidly and continuously and mix with a suitable paddle attached to a powerful, slow speed electric drill (max. 400 rpm) for 3 minutes until plastic consistency is achieved without any lump in the mortar.

Allow the mortar to rest for 2 - 3 minutes and then remix briefly, adjusting the consistency when required.

Only in exceptional conditions (e.g. hot climate) remix the mortar within its pot life when early stiffening occurs.

APPLICATION

For optimum curing of the product the temperatures during application of SikaEmaco® N 5200 must be between +5 °C and +30 °C.

First apply a thin scrape coat directly to the prepared damp substrate. Then apply SikaEmaco® N 5200 wet on wet up to the required thickness. SikaEmaco® N 5200 can be hand or trowel applied between 3 to max. 100 mm thickness.

Smoothing with a trowel or finishing by float or sponge can be done as soon as the mortar has begun to stiffen, typically after approximately 45 to 60 minutes at 20°C.

CURING TREATMENT

SikaEmaco® N 5200 is basically self-curing. In case dry, hot and windy conditions protect the freshly applied mortar for at least 4 hours.

Protect the freshly applied material against rainfall for minimum 24 hours.

CLEANING OF TOOLS

Tools and mixer must be cleaned immediately after use with water. Cured material can only be removed mechanically.
