UC Leveller to ensure successful installation of large format tiles


With the popularity increasing for large format floor tiles it is important to consider how tiling over uneven floors can cause each large tile to become uneven and end up with corners and edges higher than the surrounding tiles.

The best way to overcome this issue and provide a flat surface to tile over is to use a levelling compound prior to tiling.

MDC tiles and Mosaics recommends UC Leveller made by Mapei.


At a glance UC Leveller is

    • •A fast hardening smoothing compound – flooring can be installed after 24-48 hrs (depending on thickness and drying conditions)
    • •For thicknesses from 3mm to 70mm in interiors applications – More than one application can be made without significant shrinkage that might cause cracks.
    • •Suitable for use where resistance to heavy loads and traffic is required


UC Leveller is used when

  • •Tiling over existing ceramic tile, Natural Stone and Terrazzo
  • •Smoothing for underfloor heating installations
  • •Smoothing of concrete slabs
  • •Smoothing of cement-based and anhydrite screeds


Best practice tips when using UC Leveller

  • •Must be used within 20-30 minutes of mixing each batch (at 23 degrees C.)
  • •Use clean water and continually mix until lump free mix is obtained.
  • •Let the mix sit for a few minutes and then mix again briefly.
  • •Do Not use as a leveller over timber substrates
  • •Do Not use in a thickness less than 3mm
  • •Cracks and crazing in cement substrates must be repaired prior to application
  • •All surfaces must be solid and clean of materials which may interfere with bonding.
