General guidelines on storage and application

  • STORAGE - Keep dry in a damp proof shed on raised platform or wrapped in plastic sheeting. Cement must be fresh and not lumpy. Do not keep cement for more than three [3] months.
  • MIXING - Use the same size of the container for measuring all the materials in a batch and follow guidelines on proportions. Mix thoroughly to achieve uniform colour. Add water as you mix but avoid adding excess.
  • WATER - Use minimum amount of water required to make the mix workable. Excess water will make the concrete or mortar weak.
  • PLACING - For concrete, place as close to the target as possible. Compact using rod, spade or tamper to remove all air. Finish to desired levels and texture.
  • CURING - Concrete or plaster: Keep moist for at least seven days to allow good strength development. Protect plaster from direct sunshine and strong winds by covering with plastic sheeting or damp sand.
  • HEALTH AND SAFETY-Full protective clothing must be worn when handling cement; that is gloves, dust masks, gumboots.
  • FIRST AID-Immediately rinse eyes and skin with copious amounts of water and seek medical attention if necessary.
