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:
|Curing Efficiency Index, BS 7542, 1992||
|Loss of Water In 72 Hours (kg/m2), ASTM C156-93||
|Liquid Membrane Forming Compound For Curing Concrete, ASTM C309-93||
|Specific Gravity at 25˚C||0.85 – 0.95|
|Dry Film Colour||Clear film|
|Dry Film @30 oC (approx.)||30min-1hrs|
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.
