CONCURE WB STD

Concure WB is a white, low-viscosity wax emulsion which incorporates a special alkali reactive emulsion breaking system. This system ensures that the emulsion breaks down to form a nonpenetrating continuous film immediately upon contact with a cementitious surface.

This impervious film prevents excessive water evaporation which in turn permits more efficient cement hydration, thus reducing shrinkage and increasing durability. Once formed, the membrane will remain on the concrete surface until eventually broken down and eroded by natural weathering.

Where it is required to apply a further treatment to such concrete surface, it may be necessary to remove the membrane remaining after curing by wire brushing or other mechanical means. The use of curing membranes on internal floor slabs is generally to be avoided where additional surface fi nishes are to be applied. Concure WB is however ideal where the concrete surface of a fl oor slab is to be left as ‘fi nished’

Advantages:

• Single application : Forms moisture barrier
• No other curing necessary : Eliminates use of water, hessianor sand completely.
• Reliable : No risk of erratic or poor curing and ensures that cement hydrates effi ciently
• Ensures hard-wearing surface : Minimises risk of drying shrinkage, cracks and dusty surfaces.
• Easy and safe spray application: Non-toxic and nonflammable.

Standards compliance
Curing efficiency : Concure WB Std curing agent complies withASTM C309-90 standard.
