ATLAS SAM 200 - self-leveling rough floor (25 - 60 mm)

Levels substrates in the range of 25 – 60 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.
Ideal for installation of electric or water floor heating system – very good heat conductivity, better than cement-based products; tightly covers heating pipes.
Recommended for leveling surfaces of existing subfloors with heating systems.
Element of the floor - ceilings acoustic insulation – in combination with elasticized EPS, ATLAS EXPANSION JOINT PROFILES and polyethylene foil.
Can be applied in dry rooms – as the substrate based on high quality anhydrite, it can be used only indoors in dry rooms: living rooms, hallways, halls, salons, offices, corridors, waiting rooms, etc.

The main characteristics

  • anhydrite-gypsum based
  • practically contractionless – no need of expansion joints for up to 50 m²
  • enables adjustment of the application consistency
  • conducts heat well – perfect for floor heating system
  • self-leveling – facilitates application

The main parameters:

  • consumption: 20 kg / 1 m²/ 10 mm of layer thickness
  • compressive strength: min. 16 N/mm²
  • layer thickness: 25 ÷ 60 mm

Types of finishing layers

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

Types of possible arrangements

  • bonded - thickness 25 - 60 mm – when substrate is a good quality concrete, cement or anhydrite subfloor (with or without floor heating)
  • on separation layer - thickness 30 - 60 mm – when the substrate is of poor quality, not guaranteeing proper adhesion - dusty, cracked, oil soaked, dirty, very absorptive; the separation layer can consist of, e.g. PE foil 0.2 mm thick
  • floating – thickness 35 – 60 mm – applied 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.


Spreading properties – enables easy horizontal surface execution even in large rooms, without using guide strips and mass raking up with rules.
Compressive strength: ≥ 16.0 N/mm².
Flexural strength: ≥ 5.0 N/mm².
Limited contraction – the possibility of contraction cracking during setting is reduced to the minimum – this enables execution of working fields of up to 50 m² in area without expansion joints.
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.
