Curing Compund


Mitchell’s Hardocure WB is an economical and highly efficient liquid compound for concrete curing. Hardocure WB is a white pigmented, slightly viscous liquid suitable for spray or brush application. When applied to freshly finished concrete it dries to form a continuous film providing a stain free surface resistant to dusting and penetration of oils, fats and other mild chemicals.


Hardocure WB complies with the requirements of ASTM C-309 and AASHTO M148.


Hardocure WB prevents the rapid evaporation of water from the surface thereby ensuring adequate hydration of cement required for strength development and prevention of drying shrinkage cracking. It is most suitable for mass concreting and applications where huge areas are involved such as industrial floors and roofs, canals, roads, bridges, tunnels, dams, water tanks, runways etc. Hardocure WB does not form a permanent film and as such is not required to be removed for subsequent surface applications such as paints, plasters, tiles etc.


Economical and Labour saving Improves concrete strength gain Reduces drying shrinkage cracking Improves surface impermeability Improves surface resistance against aggressive liquids Produces a resilient, dust free surface Fully compatible with further surface treatments.

Hardocure WB is simply applied, preferably by spray on fresh concrete, approximately 1 to 2 hours after finishing. To obtain maximum curing efficiency, Hardocure WB should be sprayed as soon as the bleed water disappears from the surface. Hardocure WB should be sprayed evenly over the entire surface leaving no untreated area. Puddles should not be allowed to form and special care may be exercised at corners and edges.
It is recommended that Hardocure WB may not be diluted or mixed with other materials.
If spraying is not possible then Hardocure WB may be applied using soft brush or roller. In this case though the concrete surface should be allowed to harden enough so that the brush bristles do not affect the surface finish or texture.


Depending on surface finish, temperature, humidity and other atmospheric conditions, Hardocure WB is applied at a rate of 40 – 60 sft per liter.


Hardocure WB is available in 210 Liter Drums.
