Estocure R90

High Efficiency Concrete Curing Compound


Estocure R90 curing compound is a liquid curing compounds for the prevention of premature water loss in concrete.

Estocure R90 is applied to fresh concrete surfaces to form a fast dry, thin flexible and tough, impervious membrane which protects the concrete from rapid water evaporation during initial curing stages, thereby assisting towards obtaining maximum strength, durability and helping towards the elimination of shrinkage cracks and surface dusting

Estocure R90 have been tested by SIRIM BHD, in accordance to BS 7542:1992, on Curing Efficiency Index and complied with the specification in this data sheet.


Estocure R90 is particularly useful in large areas of exposed concrete such as:

  • Roof & bridge decks
  • Aprons, hard standing & retaining walls
  • Pre-stressed beams and piers, etc
  • Highways, runways and taxiways
  • Column, beam & precast unit


  • High curing efficiency enable cement to hydrate better
  • One time application reduces labour cost
  • Reduce surface shrinkage & cracking
  • Save time and eliminates need for damp Hessian and polythene sheet
  • Disintegrated under ultra violet light or abrasion.
  • Proven and predictable performance

Standards Compliance

  • BS 7542:1992
  • ASTM C156-93
  • ASTM C309-93 Type 1
  • BS 5750

Application Instructions


Estocure R90 products are supplied ready to use and should not be diluted with any forms of solvent.  Stir well before use.

All loose particles should be removed and honeycomb to be repaired. Estocure R90 is applied in a thin even coat using spray equipment to the fresh concrete immediately after the  free surface water has evaporated. Do not apply if bleed water is forming, or is present on the concrete surface.

The nozzle of the spray should be held approximately 500mm from the concrete surface and passed back and forth to ensure complete coverage.

After application of Estocure R90, it should be protected from rain for at least 3 hours.

Total disintegration of the membrane normally occurs after 5 weeks of application if the application rate is correct (5m2/litre).

Where subsequent surface treatment is to be undertaken before total disintegration of the membrane, Estocure R90 film shall be removed.

Estocure R90 should not be applied to dry concrete. It is imperative that the concrete be wet before applying Estocure R90. If this is not done, permanent staining will result.
