Cementaid Calcure C30 is a sprayable, water-based wax emulsion concrete curing compound designed to help retain moisture in freshly placed concrete. By forming a temporary membrane over the concrete surface, Calcure C30 reduces rapid moisture loss and supports proper cement hydration during the critical early curing period.

Supplied in a 20-litre container, Calcure C30 is particularly suited to large concrete slabs and exposed areas where traditional water curing, ponding or wet-hessian methods may be difficult, labour-intensive or costly.

Key Features & Benefits

• Effective moisture retention: Forms a membrane over fresh concrete to reduce rapid evaporation and moisture loss.

• Water-based formulation: Supplied as a water-based wax emulsion for spray application.

• Easy spray application: Designed for efficient application across large concrete areas.

• High-efficiency curing: Helps provide the moisture retention required for effective cement hydration.

• Large-area coverage: Suitable for extensive concrete slabs and exposed concrete surfaces.

• Standards compliant: Conforms to AS 3799 requirements for liquid membrane curing compounds and RTA 3202 specifications.

• Versatile application: Can also be used as a temporary de-bonding agent when applied in multiple cross-coats.

Common Applications

Calcure C30 is particularly suitable for curing:

• Large concrete slabs

• Industrial floors

• Commercial concrete slabs

• Roads and pavements

• Exposed concrete structures

• Large-scale concrete pours

• Concrete surfaces where water curing is impractical

• Projects where wet-hessian curing would be labour-intensive or costly

How Calcure C30 Works

Fresh concrete needs adequate moisture during the early stages of curing to allow cement hydration to continue. If water evaporates too quickly from the surface, the concrete may not achieve its intended performance and can become more susceptible to surface defects and shrinkage-related problems.

Calcure C30 forms a temporary wax-based membrane over the fresh concrete surface. This membrane helps reduce evaporation, allowing the concrete to retain moisture during the curing period.

This makes Calcure C30 particularly useful on large or exposed concrete surfaces where maintaining continuous wet curing can be difficult.

Additional Use as a De-Bonding Agent

Calcure C30 may also be used as a temporary de-bonding agent when applied in multiple cross-coats.

This can provide an additional application option on suitable projects. Always confirm compatibility with the intended substrate, subsequent materials and project specifications before using the product for this purpose.

Important Considerations

Because Calcure C30 is a wax-based curing membrane, the cured surface may not be suitable for direct application of certain subsequent finishes.

The membrane can interfere with the adhesion of:

• Tile beds

• Paint coatings

• Adhesive systems

• Soft floor coverings

• Other bonded finishes

Where subsequent finishes are required, the curing membrane may need to weather sufficiently or be mechanically removed before the next coating, adhesive or flooring system is installed.

Always check compatibility and the manufacturer's recommendations before applying subsequent finishes.

Why Choose Cementaid Calcure C30?

For large-scale concrete projects, maintaining adequate moisture during curing can be challenging. Traditional methods such as water ponding, water spraying and wet hessian can require significant labour and ongoing monitoring.

Cementaid Calcure C30 provides a practical spray-applied alternative by creating a temporary moisture-retaining membrane over fresh concrete. Its high coverage rate and suitability for large exposed slabs make it a useful solution for contractors working on commercial, industrial and civil concrete projects.
