For spraying on freshly cast concrete, or newly exposed concrete surfaces after removal of form work, to form a temporarymembrane which will retain suffi cient moisture for eff ective curing to take place. Used for concreting generally but especiallyuseful for large areas of concrete such as pavements, runwaysand bridge decks; also for vertical or sloping surfaces as ontowers, chimneys, canal linings, columns and beams, wherewater curing is diffi cult or unreliable. The curing compound isused for the curing of Dry Lean Concrete.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 thatcement hydrates effi ciently. Ensures hard-wearing surface : Minimises risk of dryingshrinkage, cracks and dusty surfaces. Easy and safe spray application: Non-toxic andnonfl ammable.Standards complianceCuring effi ciency : Concure WB Std curing agent complies withASTM C309-90 standard.Description :Concure WB Std is a white, low viscosity wax emulsion whichincorporates a special alkali reactive emulsion breaking system. This system ensures that the emulsion breaks downto form a non penetrating continuous fi lm immediately uponcontact with a cementitious surface. This impervious fi lmprevents excessive water evaporation which in turn permitsmore effi cient cement hydration, thus reducing shrinkage andincreasing durability.Once formed, the membrane will remain on the concretesurface until eventually broken down and eroded by naturalweathering. Where it is required to apply a further treatmentto such concrete surface, it may be necessary to remove themembrane remaining after curing by wire brushing or othermechanical means.The use of curing membranes on internal floor slabs isgenerally to be avoided where additional surface fi nishes areto be applied. Concure WB Std is however ideal where theconcrete surface of a fl oor slab is to be left as ‘fi nished’.
