Planitop Smooth & Repair R4
Description

Structural R4-class, quick-setting, shrinkage compensated, thixotropic, fibre-reinforced, cementitious mortar, applied in a single layer from 3 to 40 mm thick, for repairing and skimming concrete.

Residual GreenHouse Gas emissions measured throughout the life cycle of this product using Life Cycle Assessment (LCA) methodology, verified and certified with EPDs, have been offset for the year 2026 through the acquisition of carbon credits in support of forestry protection projects.

Key Features
  • Structural repair.
  • Quick-setting.
  • Can also be applied at low thickness.
  • Natural fine-grained finish.
  • High crack resistance.
  • Can be painted directly.
  • Once hardened, Planitop Rasa & Ripara R4 features the following characteristics:
  • Excellent adhesion to both existing concrete ( ≥ 2 MPa), if pre-wetted with water, and to steel reinforcement, particularly when treated with Mapefer or Mapefer 1K anti-corrosion and re-alkalising cementitious mortars, certified EN 1504-7 “Reinforcement corrosion protection”;
  • High dimensional stability, and therefore a low risk of cracking and crazing both during the plastic phase and after hardening;
  • Thermal compatibility with freeze/thaw cycles, measured as bond strength according to EN 1542;
  • High resistance to carbonation;
  • Impermeability to water.
  • Planitop Rasa & Ripara has very low emissions of VOC to protect the health of both applicators and end users, and is certified EC1 Plus by the German association GEV.
  • Planitop Rasa & Ripara R4 contributes to the achievement of important LEED credits.
  • Planitop Rasa & Ripara R4 complies with the principles in EN 1504-9 (“Products and systems for the protection and repair of concrete structures: definitions, requirements, quality control and evaluation of conformity. General principles for use of products and systems"), and the minimum requirements of EN 1504-3 ("Structural and non-structural repair") for R2-class non-structural mortars and with the requirements of EN 1504-2 standard coating (C), according to principles MC and IR ("Concrete surface protection systems”).
Scope of Use

Structural repair and skimming of horizontal and vertical concrete surfaces, both indoors and outdoors. It is suitable for repairing structures exposed to the elements or in permanent contact with water.

Some application examples:

  • Rapid repair of damaged concrete in beams, columns, in fill walls, cornices, balcony edges, and other structural elements where a high-performance mortar is required.
  • Rapid smoothing of defects in cast concrete, such as deep honeycombing areas, spacer holes, and construction joints, before subsequent painting.
  • Repair and structural reinforcement of concrete by adding mortar.
  • Repair of precast concrete elements.
  • Repair of concrete damaged by oxidation of reinforcing bars due to carbonation.
Limitations on Use
  • Do not add water to the mix once it has started to set in an attempt to make it workable again.
  • Do not add cement or admixtures, with the exception of Mapetard ES.
  • Do not apply Planitop Rasa & Ripara R4 on smooth substrates: the surface must be roughened.
  • Do not apply Planitop Rasa & Ripara R4 on dry substrates.
  • Do not use Planitop Rasa & Ripara R4 for precision anchoring (use Mapesill or Mapesill R).
  • Do not leave bags of Planitop Rasa & Ripara R4 exposed to direct sunlight before use.
  • Do apply Planitop Rasa & Ripara R4 if the temperature is lower than +5°C.
  • Do not use Planitop Rasa & Ripara R4 if the bag is damaged or has been previously opened. 
Statement of Building Code Compliance

B1 Structure, B2 Durability and C6 Structural Stability 

  • Planitop Smooth & Repair R4 complies with the principles defined in EN 1504-9 (“Products and systems for protecting and repairing concrete structures: definitions, requirements, quality control and conformity assessment. General principles for the use of products and systems”) and the minimum requirements of EN 1504-3 (“Structural and non-structural repairs”) for structural R4-class mortars and the requirements of EN 1504-2 coating (C) according to principles MC and IR (“Concrete surface protection systems”) 
  • A suitably qualified Structural Design Engineer should specify this product based on the structural requirements of the degraded concrete structure. 
  • A Structural Design Engineer should review the NZ Building code clauses with reference to EN 1504-3, SAA/SNZ HB84:1996 and NZS 3101:2006 to confirm compliance for each specific application. 
  • Planitop Smooth & Repair R4 has an A1 rating for Fire as per euro class EN 13501-1 F2 Hazardous Building Materials: F2.3.1 
  • Planitop Smooth & Repair R4 contains a mix of cement, sand, fibres, and additives. When the product is being applied it therefore has the same hazards as fresh concrete and appropriate health and safety precautions should be undertaken. Read the products Safety data Sheet and wear the required personal protective equipment. Once this product is set and hard Planitop Smooth & Repair R4 is a non-hazardous product and does not emit any harmful gases or substance.
Other Performance Attributes
  • Residual GreenHouse Gas emissions measured throughout the life cycle of this product using Life Cycle Assessment (LCA) methodology, verified and certified with EPDs, have been offset for the year 2026 through the acquisition of carbon credits in support of forestry protection projects.
