ATLAS SMS 15 Self-Levelling Compound 25kg
ATLAS SMS 15 25kg Rapid-Setting Self-Levelling Compound
ATLAS SMS 15 is a rapid-setting, cement-based self-levelling compound designed to create smooth, even floor surfaces ready for a range of floor finishes. Suitable for interior renovation and new flooring projects, it levels uneven substrates in thicknesses from 1mm to 15mm.
With excellent flow properties and low linear shrinkage, ATLAS SMS 15 helps produce a smooth, level surface with minimal effort. Its rapid-setting formulation allows foot traffic after approximately 3 hours and ceramic tile installation after approximately 8 hours under suitable conditions.
Key Features
1–15mm application thickness: Ideal for correcting minor floor irregularities and levelling existing screeds.
Rapid setting: Suitable for projects where reducing waiting times is important.
Excellent flow: Spreads readily to help achieve a smooth, level finish.
Low linear shrinkage: Helps reduce the risk of cracking and separation during setting.
Strong finished surface: Compressive strength of at least 25 N/mm².
Versatile floor finishes: Suitable beneath ceramic tiles, carpet, PVC flooring, panels, parquet and epoxy resin flooring.
Underfloor heating: Suitable for levelling appropriate existing heated cement and anhydrite screeds.
Interior applications: Suitable for residential and commercial rooms, including kitchens and domestic bathrooms, subject to the specified installation requirements.
Suitable Applications
ATLAS SMS 15 is ideal for preparing floor surfaces before installing new floor coverings, correcting unevenness and bringing adjacent rooms to a more consistent floor level.
It can be applied manually or mechanically using suitable floor-screed pumping equipment.
