Self-levelling screed ATLAS MMS 60 20-60mm 25kg

ATLAS MMS 60 - Hybrid, self-levelling floor screed (20-60 mm)

• as substrate for tiles, laminate flooring, wooden floorboards, carpet and PVC flooring
• for all rooms with underfloor heating, including "damp" rooms
• high thermal conductivity for improved heating system efficiency
• perfectly smooth surface, no sanding required
• IQ colour – the colour changes and makes it possible to check the progress of the work

Product description:
It is the ideal material for embedding underfloor heating, electric or water-based, and for heating systems installed on the screed surface – it has very good thermal conductivity, better than cement-based products; and completely envelops the heating pipes. It heats up quickly after the heating system is switched on.
MMS 60 is also suitable for levelling existing screeds with unevenness of 20-60 mm – both if the substrate only has local irregularities and if it has already formed a continuous slope.
Raising of the floor level in the whole room – e.g. in order to level two adjacent rooms.
Recommended as a substrate for floor coverings and carpets in offices, kindergartens, schools, flats, etc.. – thanks to the smooth surface created by the fine aggregates contained in the screed.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:
The mixture of mineral binders and the addition of graphene ensure:
- a fast heat transfer from the heating system to the screed,
- heat storage in the screed,
- the maintenance of a high level of thermal comfort in the room.
Thanks to a structural 3D reinforcement, the screed can be laid on areas of up to 70 m² without expansion joints.However, it is essential to create expansion joints at wall junctions and thresholds.

Compression strength:≥ 20 N/mm².
Bending strength:≥ 4 N/mm².
Can be laid manually or mechanically- the material can be laid easily and quickly both manually and with screw pump devices and offers high efficiency during application.
