Novamix Repair Mortar RC 340

Repair mortar RC 340 from the company Novamix

  • RC 340 is a ready-to-use fibre-reinforced, thixotropic cementitious-based mortar
  • Easily applied to horizontal and vertical surfaces for structural concrete repairs
  • It has high mechanical strength with adhesion to most construction materials with a very good aesthetic result
  • CE marked with Declaration of Performance (DoP) C04378-CPR-2020402 as a mortar for structural repairs of concrete structures in buildings and civil engineering works, Class R3 according to EN 1504-3:2005
  • RC 340 is according to EN 1504-9 suitable for
  • Concrete restoration works on horizontal or vertical surfaces, Principle 3, Methods 3.1 & 3.3
  • Structural repairs of concrete and increase of the load-bearing capacity of the structure by adding mortar to columns, beams, load-bearing walls, etc. Principle 4, Method 4.4
  • Repair of carbonated concrete, maintenance and restoration of passivity, Principle 7, Methods 7.1 & 7.2
  • Levelling 5 - 30mm thick in one layer, on ceilings, horizontal and/or vertical surfaces
  • Spot restoration up to 50 mm - filling gaps, niches and small imperfections
  • As a substrate for decorative coatings of PLANOCOLOR SYSTEM on walls, floors and ceilings

Application

  • Substrate preparation - Remove loose and loose parts of concrete or cement mortar until the substrate is compact and rough with a minimum tensile strength of > 1.5 N/mm²
  • Surfaces shall be free from dust, oils, grease, rust and generally from elements that would adversely affect adhesion
  • Rusted rebars should be treated with NOVAFER , but after the use of RUST CONVERTER or cleaned by sandblasting or wire brushing on small surfaces
  • Cracks in concrete should be bonded with the two-component epoxy adhesive EPO FLUID
  • Soak the substrate with water
  • Before repairing with RC 340 remove excess water using air or a sponge
  • For further information please refer to the respective Product Data Sheets
  • Preparation of the mixture
  • Add to a suitable container water corresponding to the required quantity of powder. For 25 kg RC 340 add 4,0 - 4,5 lt of water depending on the desired workability
  • Slowly and with stirring add RC 340 to the water. Mix with an electric mixer for at least 3 minutes until complete homogenisation of the mixture without aggregates is achieved. For small quantities, mixing can also be done by hand
  • The mixture is ready for use

Method of application

  • The mixture shall be applied using a flat trowel, trowel or suitable spraying systems to ceilings, horizontal and vertical surfaces, applying sufficient pressure and thoroughly compacting the material on the surface.
  • The maximum permissible thickness is 30 mm per layer, 15 mm for ceilings
  • When a greater thickness is required, apply successive coats when the previous one starts to set and does not stick to the hand
  • The mortar must be applied under normal conditions within 60 minutes from the start of mixing
  • After this period do not attempt to mix again with water
  • Low temperatures extend the life of the mortar, while high temperatures drastically reduce its workability
  • Protect the fresh mortar from rapid drying by suitable means
  • For smoothing surfaces before applying decorative coatings PLANOCOLOR MICROCEMENT or PLANOCOLOR GRANIT, a waiting period of 3 - 10 days is recommended, depending on the thickness of the filling
  • For coating applications such as ceramic pool tiles, usually 24 - 48 hours is sufficient
