Aardcure WHC is a blend of hydrocarbon resin and densifiers to create the highest performing curing compound in the Australian market. The advanced formulation Aardcure WHC combines the benefits found in effective curing while increasing the performance and lifespan of the concrete by introducing a specific catalyst that enhances the properties of concrete at the surface during curing and for the lifespan of concrete. This unique formulation offers many advantages over existing resin based curing compounds.
Due to its unique formulation and blend of resins, Aardcure WHC will begin to break down after 7 days and, if applied at the specified application rates, will totally oxidize and leave the surface, subject to UV exposure, within 45 – 55 days of the application. This reduces the need for surface stripping in preparation for after trades.

Drying time is dependent on the temperature. The sealer is usually touch-dry in approximately 1 hour at 25˚C.
Protect the sealed surface from rain, for a minimum of 4 hours. Accessible to foot traffic after 4 hours and vehicle traffic after a minimum of 12 hours.
Coverage to meet AS3799 moisture retention is 5m² per litre per coat. Coverage for a single coats application is 100m² per 20 litre drum.
The properties of the substrate such as porosity and profile will influence the coverage rate and number of coats required.
Areas to be treated must be clean, dry, free from sawcutting debris.
Apply Aardcure WHC undiluted to the surface.
After surface finishing the concrete must be free of bleed water and sufficiently set to be firm and able to be walked on without marking or damaging the surface.
To achieve stated curing efficiency Aardcure WHC must be applied on the day of the pour and not left overnight.
Assess the application area so that a fixed volume of mixed material can be applied over a fixed area to determine the correct application rate.
Agitate the material until thoroughly mixed to ensure effective curing properties.
Effective application temperatures are between 10ºC and 35ºC.
Application is recommended via low pressure spray unit. Spray at a sufficient rate to achieve consistent coverage in even coats. A short nap roller can also be used for smaller applications.
