Additional information

Composition

Product based on special cements, selected aggregates and additives, reinforced with fibres.

Features and applications

  • Repair mortar class R3 according to EN-1504-3.
  • High adherence to concrete and medium modulus..
  • Thixotropic, without sagging in ceiling applications.
  • Water vapour permeable.
  • Balanced retraction to minimize risk of cracking.
  • Good chloride resistance.
  • Resistant to freeze-thaw cycles.
  • Excellent workability.
  • High resistance to carbonation.
  • Indoor and outdoor application.
  • Resistant to harsh weather.
  • Repairs to structural elements such as edges of balconies, roofs, parking lots, beams / pillars of commercial and residential buildings, prefabricated panels, building facades.
  • Regularization of concrete surfaces.
  • Linings of canals, tunnels, bridge cantilevers and balconies.
  • Rendering of lift shafts, manholes, etc.
  • Screeds and repair of pavements.

Substrates

  • The substrate must be sound, clean, and free of grease, oil, dust and badly-bonded parts.(minimum tensile strength of 1.5 MPa). 
  • If necessary, prepare the same preferably using mechanical means and leave the new concrete uncovered.
  • The absorbent substrates should be previously wetted until they are saturated, preventing waterlogging. Apply the product once the surface has a matt appearance.
  • If there are reinforcements, they should be clean of rust, grease, oil and other badly-bonded particles.
  • If they are rusty, they must be sandblasted or metal brushed.   Protect from corrosion with IMPLAREST C.
  • In vertical and horizontal wall joints, widen the joint by cutting it up to about 10 mm wide with a radial saw, removing the cut material afterwards.

Instructions for use

Mortar mix:

  • Add the prepared 2/3 parts water and progressively mix all of the powder while stirring.  Then add the remaining water and mix for another 2 minutes.  Do not prepare more material than what you are going to use for 30 minutes. (a +20ºC).

Application:

  • Apply MORCEMREST RF 15 with a trowel or projected with a gun, applying pressure to assure bonding and compact the material firmly.
  • MORCEMREST RF 15 can be applied in a few layers, the minimum layer thickness being 5 mm. Applications of up to 15 mm can be made on vertical surfaces without the help of formworks. The maximum thickness for horizontal surfaces is 50 mm.
  • Fill the joints completely.

Curing:

  • Protect from the wind, frost and sun during hardening.  To prevent excessive drying out, it is recommended to cover the surface with wet hessians or plastic during curing.
  • Observe protection procedures after application.

Cautions and recommendations

  • Do not add more than the recommended amount of water and do not re-knead.
  • Do not apply below 5ºC nor above 30ºC.
  • Do not add cement, sand or any other substance which will alter the product properties.
  • On substrates exposed to exceptional reasons it is advisable the employ of epoxi based bonding layer, IMPLAREST EPW.
  • Instruments and tools should be cleaned with water immediately after use to prevent material hardening, which has to be eliminated by mechanical means.
  • Contact the Technical Department for any application not specified in this data sheet.
  • For any information regarding the safe handling, transport, storage and use of the product please refer to the updated version of the Product Safety Datasheet.
  • If applied manually ensure the coats are strongly compacted; in areas of difficult compaction it is recommended its mechanical application.
  • For further information on how to prepare concrete or steel framework; consult the recommendations given by the UNE-EN-1504-10 guideline.

Packaging

MORCEMREST RF 15 comes in bags of 25 Kg of powder.
