Estocure P

Concrete Curing Compound

Download Data Sheet


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

Estocure P 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 P 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


  • 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

Application Instructions


Estocure P is supplied ready to use and should not be diluted with any forms of solvent / water. Stir well before use.

Estocure P is applied in a thin even coat using spray equipment to the fresh concrete immediately after the free surface water has evaporated. All loose particles should be removed and honeycomb to be repaired.

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

After application of Estocure P, 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 P film shall be removed.

Estocure P should not be applied to dry concrete particularly on vertical surfaces or soffit of concrete, which may have partially dried out by being retained in shuttering. It is imperative that the concrete be well wetted before applying Estocure P. If this is not done, permanent staining will result.
