ATLAS POSTAR 80

fast setting cement floor

ATLAS POSTAR 80

Most important features

  • fast drying – further works just after 24 hours
  • fast setting - foot traffic after 3 hours
  • limited linear shrinkage
  • high compressive strength ≥ 40.0 N/mm²
  • excellent cohesion, under parquets and epoxy floors

Product description

Forms screed or floor 10 - 80 mm thick - layer thickness depends on the expected structural arrangement.
Recommended for quick repairs – fast setting - rapidly reaches the operational parameters, therefore the technological breaks are shorter and application of subsequent layers quicker: foot traffic just after 3 hours; fixing the tiles - just after 24 hours.
Can form screed for top flooring layers e.g. parquet, epoxy floors and coats - characterised by high cohesion and resistance to setting forces, which occur within the joint with flooring layer, e.g. during expansion and contraction of wood resulting from the changes of humidity.
Forms floor characterised by high abrasion resistance – recommended for residential housing, warehouses, industrial premises, on driveways, terraces, etc.
Can be installed as screed with heating system – does not require elastifying admixtures, conducts heat well.
Enables forming a slope and repairs of concrete surfaces, stairs, slabs, floors.

Main properties

  • Fast-drying - the residual moisture content below 2.6% for screed approx. 4 cm thick after 24 hours since application (in standard conditions).
  • Fast setting – rapid strength build up within the first day of setting.
  • Thick plasticity - mortar consistency makes it easy to spread, float and to form even surface.
  • Compressive strength ≥ 40.0 N/mm² - recommended for any surfaces exposed to medium and high load.
  • Flexural strength ≥ 7.0 N/mm².
  • Abrasion resistance ≤9.5 cm³/50 cm² - acc. to Böhme (Technical Approval AT-15-8462/2010).
  • Low linear shrinkage - minimum changes in linear dimensions during screed drying (approx. 0.6 mm/rm) limit the risk of cracking.

Main parameters

  • Mixing ratio (water/dry mix): approx. 0.08 l/1 kg
  • Min./max. screed or floor thickness: 10 mm / 80 mm
  • Pot life: min. 30 minutes
  • Foot traffic:after approx. 3 hours
