ATLAS POSTAR 80 - fast-setting, fast-drying cement-based floor (10 - 80 mm)
and contraction of wood resulting from its humidity changes.
The main characteristics
- fast-drying – work can be continued after 24 hours
- fast-setting - allows foot traffic after 3 hours
- limited linear shrinkage
- high compressive strength: >40 N/mm²
- high cohesion, under parquets and epoxy screeds
The main parameters:
- consumption: 20 kg /1 m² / 1 cm of thickness
- layer thickness: 10-80 mm
- compressive strength: min. 40 N/mm²
Types of finishing layers
- ceramic and stone tiles,
- PVC flooring,
- carpet flooring,
- floor panels.
Types of possible arrangements
- bonded floor - thickness 10 - 80 mm – substrate of good quality concrete, cement screed (with or without floor heating)
- on separation layer - thickness 35 - 80 mm – when the substrate is of poor quality, not guaranteeing proper adhesion - dusty, cracked, oil soaked, dirty, very absorbable; the separation layer can consist of, e.g. PE foil 0.2 mm thick
- floating - thickness 40 - 80 mm – installed onto thermal or acoustic insulation of: expanded polystyrene of proper hardness, floor hardened panels of mineral wool, etc.
- heating – the layer thickness over the heating layer should be at least 35 mm
- Fast-drying - the residual moisture content for subfloor thickness of 4 cm is reduced to less than 2.6% after 24 hours from application (in standard conditions)
- Fast-setting - rapid strength development during the first day of setting.
- Thick plasticity - the mortar is easy to spread, float and allows to reach even surface.
- High compressive strength ≥ 40.0 N/mm2 - recommended for any surfaces subject to medium or high loads.
- Flexural strength: ≥ 7.0 N/mm2.
- Abrasion resistance ≤ 9.5 cm³/50 cm2 - according to Böhme (Technical Approval AT-15-8642/2010).
- Very low linear contraction – minimum linear changes of the subfloor during drying (at 0.6 mm/rm) limit the possibility of cracking.
- Changes in residual moisture content with time. The results were obtained at normal conditions at ca. 20°C and 55-60% humidity. Every time prior to the application of flooring materials it is necessary to perform humidity tests (CM method).
