Application

For the smoothing and levelling of uneven subfloors before laying decorative floor coverings. It can be laid over most common substrates including:

  • Concrete.
  • Sand/ cement screeds.
  • Stone.
  • Anhydrite screeds.
  • Terrazzo and quarry tiles.
  • Asphalt.
  • Strong, rigid subfloors.


It should not be used over old tackifer or water soluble residues.

Description

A two-part, protein and casein free, cementitious underlayment with improved flow for smoothing uneven floors prior to laying decorative floor coverings. It is suitable for use with warm water underfloor heating installations, provided a maximum surface temperature of 27°C is not exceeded.

The levelling compound is not affected by glazed areas. Heating must be switched off at least 48 hours before and after applying the compound.

Features and benefits:

  • Can be used under a surface damp-proofing membrane (DPM).
  • Good workability and flow characteristics, is self-smoothing and can be trowelled to a feather edge.
  • Protein and casein free, making it suitable for use in biologically sensitive areas.
  • The low odour formulation makes it suitable for use in occupied buildings.
  • The moisture tolerant formula enables it to be used to smooth rough, textured subfloors prior to the application of DPMs in buildings incorporating a base DPM.
