fast drying cement screed

ATLAS POSTAR 20

Most important features

  • fast drying – further works just after 5 days
  • foot traffic after 24 hours
  • limited linear shrinkage
  • high compressive strength ≥ 20.0 N/mm²
  • for places exposed to permanent dampness

Product description

Forms screed 10 - 80 mm thick - layer thickness depends on the expected structural arrangement (see table below).

Recommended for installation of screeds in residential housing, public access buildings, 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 3% for screed approx. 4 cm thick after 5 - 6 days since application (in standard conditions).
  • Thick plasticity - mortar consistency makes it easy to spread, float and to form even surface (horizontal or sloped).
  • Compressive strength ≥ 20.0 N/mm².
  • Flexural strength ≥ 4.0 N/mm².
  • 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. 0.11 l/1 kg
  • Min./max. screed thickness: 10 mm / 80 mm
  • Pot life: min. 30 minutes
  • Foot traffic: after approx. 24 hours
