Direction to Use

  • Always add powder to water & not other way round
  • Pot life of the product is 15mins, hence mix only as much material which can be consumed in 15mins
  • Do not alter contents of material which has already begun to set
  • Never keep bags open - Even while working, fold mouth of bag after removing required material, as gypsum being a hegroscopic material it attracts moisture
  • Setting time of the product is an inherent quality of the product & independent of the amount of water added. For longer setting time retarder may be used
