  • Work at an ambient temperature between 5° C and 25° C.
  • Ambient temperature can actually affect application time as follows:
    • about 5°C: < 90 minutes
    • about 20°C: < 45 minutes
    • about 25°C: < 5 minutes
  • In hot weather, store bags at a temperature below the ambient air and mix cold water to extend workability time.
  • Ensure that all mould/formwork joints are properly sealed to prevent leakage; in case they are not, use silicone joints to fill leaks, if any.
  • All surfaces in contact with i.design EFFIX CREA should be clean and coated with a thin layer of highgrade formwork/mould release oil. The use of clean, proper brushes or clothes is absolutely necessary for this step.
  • Provide effective protection against desiccation (dryingout), especially when manufacturing thin and long elements (i.e. those featuring a significant exposed surface/volume ratio). The use of wet non-woven fabrics and plastic sheets or the even distribution of an antievaporation agent has been shown to provide an adequate solution to the problem.
  • Protect from frost, wind and direct sun during setting and hardening.
  • Removal of formwork/mould can be performed after 18-24 hours.
  • After demoulding, elements must be kept wet or be immersed in water at 20°C for at least 7 days. During early curing, avoid storage in hot, dry and windy weather.
  • The use of a suitable surface protection product is highly advisable.
