ATLAS SMS 30 - fast-setting, self-leveling subfloor (3-30 mm)

Levels substrates in the range of 3 – 30 mm – both when the substrate has only local irregularities and when it is executed with a slight slope.
Elevates the floor level in the whole room – e.g. when necessary to equalize the level in two adjacent rooms.
May be used in dry and wet rooms – in living rooms, antechambers, halls, parlours, offices, corridors, waiting rooms, etc.
May be used in rooms of increased humidity, such as house bathrooms.
Recommended as subfloor under facings in offices, kindergartens, schools, apartments etc. –
due to fine aggregate it forms smooth surface.

The main characteristics

  • under parquet, tiles, panels, carpet flooring
  • foot traffic just after 4 hours
  • for equalizing levels in floor repairs
  • low linear contraction

The main parameters:

  • consumption: 20 kg / 1 m² / 10 mm of layer thickness
  • compressive strength: ≥ 30.0 N/mm²
  • layer thickness: 3 ÷ 30 mm

Types of finishing layers

  • tiles, 
  • PVC flooring, 
  • carpet flooring, 
  • floor panels,
  • parquet.

Types of possible arrangements

  • bonded - thickness 3 - 30 mm – good quality concrete, cement or anhydrite subfloor (with or without floor heating).


Perfect spreading – enables easy horizontal surface execution even in large rooms, without using guide strips and mass raking up with rules.
Fast-setting - rapid strength build-up enables foot traffic just after 4 hours of the subfloor application.
Compressive strength: ≥ 30.0 N/mm².
Flexural strength: ≥ 7.0 N/mm².
Very low linear contraction – minimum subfloor linear changes during setting (≤ 0.6 mm/rm) limit the possibility of its cracking and loosening of weak substrates (of low cohesion).
Suitable for manual and machine application – it can be easily and quickly applied both manually and with the use of machines equipped with helical pumps, obtaining high efficiency.

Super geklappt, sehr guter Preis, meine nächsten Bestellungen mache ich bestimmt wieder hier.
10qm Bad in 30min 10-30mm ausgeglichen. Tolles Ergebnis beim ersten Versuch. Sehr zufrieden mit dem Produkt. Es muß zügig gearbeitet werden.
Gute Fließeigenschaften, neigt kaum zu Blasenbildung, nach 30 Minuten merklich am fest werden.
Produkt von Preis/Leistung zu empfehlen. Die 40 Minuten Verarbeitungsdauer gelten aber nur bei optimalen Bedingungen. Mein Tipp: eher in 20 Minuten verarbeiten. Sonst super, es hat sich 24 Stunden später super darauf fliesen lassen
