Water based concrete curing compound

Uses

For spraying on freshly cast concrete, or newly exposed concrete surfaces after removal of form work, to form a temporary membrane which will retain sufficient moisture for effective curing to take place. Used for concreting gener- ally but especially useful for large areas of concrete such as pavements, runways and bridge decks; also for vertical or sloping surfaces as on towers, chimneys, canal linings, columns and beams, where water curing is difficult or unreliable.

Advantages

1. Single application : Forms moisture barrier for whole of the curing period.
2. No other curing necessary : Eliminates use of water, hessian or sand completely.
3. Reliable : No risk of erratic or poor curing and ensures that cement hydrates efficiently.
4. Ensures hard-wearing surface : Minimises risk of drying shrinkage, cracks and dusty surfaces.
5. Easy and safe spray application: Non-toxic and nonflammable

Concure WB Clear is a white colour, low viscosity milk emul- sion which incorporates a special alkali reactive emulsion breaking system. It is supplied as a white emulsion which forms a white film on drying. This system ensures that the emulsion breaks down to form 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, 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 finishes are ensuring complete coverage of the surface. Rate of application depends on requirements but is typically within the range of 200 to 285 ml/m2.
