Cement Qualification
INSEE Dang is suitable for masonry and plastering works where minimal mortar shrinkage and smooth finishing are required. The INSEE dang is also suitable for ordinaryconcrete works such as general housing works, concrete pavement, concrete tiles, piers, drain pipes, septic tanks, water tanks, etc.
Recommendations
  • Clean the surface before plastering for better adhesion.
  • Moisten the wall before plastering to avoid cracks from rapid water absorption.
  • Do not directly expose the just finished plastered wall to sunlight to avoid cracks from heat and rapid water loss
  • For plastering works, curing is highly recommended especially 1-3 days after plastered (in this period plastered walls should be kept damp)
    in order to avoid cracks and to help concrete to develop itscompressive strength.
  • Keep the cement under shade and cool-dry area.
  • Do not store cement for more than 2 months and once opened should be finished within 1-2 day
