  • pot life up to 45 minutes

Product description

ATLAS SMS 80 is manufactured as a dry mix based on cement.
Levelling of substrates within a range of 25-80 mm – both when the substrate has only local irregularities and when the entire substrate has a slight slope.
Raising of the floor level in the whole room – e.g. in order to level two adjacent rooms.
Suitable for all types of rooms - in “wet” rooms the screed requires waterproofing before laying the floor top coat.
Types of floor top coats – tiles, laminate flooring, epoxy floors as well as PVC and carpet coverings.
It is a universal product and can be used as:
- levelling layer bonded to the substrate – thickness 25 - 80 mm – when the substrate is of good quality, e.g.: concrete (with or without underfloor heating), terrazzo, etc.
- self-supporting screed on a separating layer – thickness 35-80 mm – when the substrate is of poor quality and does not ensure proper adhesion - e.g.: dusty, cracked, oily, dirty, highly absorbent; the separating layer may be e.g. PE foil 0.2 mm thick,
- floating screed - thickness 40-80 mm - laid on thermal or sound insulations made of: polystyrene foam boards of adequate hardness, hard floor boards made of mineral wool, etc.
- screed on underfloor heating – thickness over the heating layer or jus pipes should be at least 35 mm - it does not require additional reinforcement.

Packaging:
Foil bags 25 kg.

Main properties

  • Perfect spreading – ensures perfectly smooth and levelled surfaces even in large rooms, no battens nor screeding level needed.
  • Suitable for manual and mechanical application – easy and quick application manually and mechanically. High application efficiency is reached with helical pump units.
  • Very low linear contraction - minimum change in linear dimensions during screed drying (≤ 0.6 mm/rm) limits the risk of cracking and loosening of weakened substrates.
  • A long pot life (45 minutes) ensures comfort of application, particularly on large surfaces.

Main parameters

  • Compressive strength: ≥ 20.0 N/mm².
  • Flexural strength: ≥ 5.0 N/mm².

  • Consumption:
    Average consumption is 18 kg of mortar for 1 m²/10 mm layer thickness.
