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 suffi cient moisture for effective curing to take place. Used for concreting generally 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 diffi cult or unreliable. The curing compound is used for the curing of Dry Lean Concrete.

Advantages

 Single application : Forms moisture barrier

 No other curing necessary : Eliminates use of water, hessian or sand completely.

 Reliable : No risk of erratic or poor curing and ensures that cement hydrates efficiently.

 Ensures hard-wearing surface : Minimises risk of drying

shrinkage, cracks and dusty surfaces.

 Easy and safe spray application: Non-toxic and nonflammable.

Description :

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 non penetrating continuous fi lm immediately upon contact with a cementitious surface. This impervious film prevents excessive water evaporation which in turn permits more effi cient 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 to be applied. Concure WB is however ideal where the concrete surface of a fl oor slab is to be left as ‘finished’.

Coverage rate

The recommended coverage rate is between 3.5 and 5.0 sq.m / litre ( 0.200 to 0.285 litres/sq.m). Coverage rates outside this recommended range may be used if necessary and suitable to meet specific requirements.

Application instructions

Application

Exposed concrete slabs : Concure WB should be spray applied on to the newly placed concrete slab as soon as possible after it is free from visible surface water, e.g. typically 1 to 2 hours after placing.

Shuttered and precast concrete : Concure WB curing agent should be spray applied to all surfaces as soon as formwork has been removed or the element demoulded.

In all cases the nozzle of the spray should be held approximately 450mm from the concrete surface and should be passed back and forth to ensure complete and even coverage. The pump pressure should be maintained at a level to produce a fine spray ensuring complete coverage of the surface.

Rate of application depends on requirements but is typically within the range of 200 to 285 ml/m2.
