INSEE Poon Keaw
General Mixed Cement For General Bricklaying And Plastering
INSEE Poon Keaw is mixed cement that can be used for general bricklaying and plastering works.
Cement Qualification
INSEE Poon Keawis suitable for general bricklaying and plastering works which does not require high specific strength such as concrete column casting, small slab concrete, concrete pavement, concrete tiles, drain pipes and etc. Its specification conforms to the Thai Industrial Standard for Mixed Cement TIS 80 -2550
Recommedation
- 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 its compressive 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 with in 1-2 day
