ATLAS POSTAR 20
fast drying cement screed
- foot traffic after 24 hours
- under tiles, panels, epoxy coatings
- for making sloping layers on terraces and balconies
- perfect for underfloor heating
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. Types of finishes - ceramic and stone tiles, PVC and carpet flooring, panels, epoxy coatings.
Types of arrangements that can be created:
- bonded to substrate - thickness 10-80 mm - substrate is good quality concrete, cement base (with or without underfloor heating) - on a separating layer - 35-80 mm thick - when the substrate is of poor quality, not guaranteeing proper adhesion - dusty, cracked, oily, dirty, highly absorbent; the separating layer may be, for example, PE foil with a thickness of 0.2 mm thick
- Floating - 40-80 mm thick - laid on thermal or sound insulation made of: polystyrene boards of the appropriate hardness, underfloor hardened mineral wool boards, etc.
- heating installation - the thickness of the screed over the heating installation should be at least 35 mm

Properties
- ATLAS POSTAR 20 is produced as a dry mixture of Portland cement, quartz fillers and modifying additives.
Thick-plastic - the working consistency of the mortar allows easy spreading of the mix, blending in and achieving an even surface (hor- izontal or with a slope).
Compressive strength: ≥ 20.0 N/mm².
Flexural strength:4.0 N/mm².
It has very low linear shrinkage - minimal linear changes in the screed during drying (on the order of 0.6 mm/mb) reduce the possibility 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
