Fosroc Concure WB30 Curing Compound 20L

Product Description

Concure WB30 is a water-based wax emulsion curing compound that conforms to AS3799. It forms a non-penetrating continuous film immediately upon contact with a cementitious surface. This impervious film prevents excessive water evaporation, which in turn permits more efficient cement hydration. This reduces shrinkage and increases durability.

Features:

• Reduces surface shrinkage and cracking by eliminating moisture loss from exposed surfaces
• Increases concrete strength and dusting resistance
• Eliminates the need for damp hessian, sand or polythene
• Rapid film formation
• Enables concrete to hydrate more efficiently
• Non-flammable; non-toxic
• Suitable for potable water applications
• Complies with requirements of AS/NZS 4020:2005

Ideal for:

• Curing large areas of concrete construction such as runways, motorways or bridgeworks

APPLICATION

Mixing:

Concure WB30 should be thoroughly mixed prior to use.

Placement:

Concure WB30 should be spray applied to the surface of newly placed concrete. The compound should be applied as soon as possible after the concrete is free from surface water. The nozzle of the spray should be held approximately 450 mm from the concrete surface and should be passed back and forth to ensure complete coverage. The pump pressure should be maintained at a level producing a fine spray.

Concure WB30 should not be continuously re-circulated through high shear gear pumps when used in concrete train application. If continuous re-circulation is essential the sprayer should be fitted with a low shear diaphragm pump. Rate of application should be 5 metres square per litre.

Clean Up:

Immediately after use the spraying equipment should be cleaned out with water. If the spray nozzle becomes blocked with wax particles these can be easily removed using white spirit or similar fluid.

Storage:

Shelf life of 18 months when stored at moderate temperatures. Containers should be kept airtight.

Yield:

Coverage rate 5sqm per litre
