Today there is a growing demand for larger format ceramic and natural stone tiles. This necessitates proper specification and execution of floor surface preparation, particularly in relation to floor flatness, which is critical to any successful floor covering installation. To ensure a higher quality appearance and reduced life cycle cost, the ceramic tile industry has responded to large format tile trends with updated reference standards and guidelines that provide more specific definitions for large format tile as well as tighter tolerances for substrate flatness.

Substrate flatness is best achieved through the application of a flowable and cementitious self-leveling underlayments (SLU).

This presentation will review: 

  • Potential conditions in the floor subsurface and the industry’s requirements related to them
  • Proper specification and installation of a self-leveling underlayment over some common flooring conditions and substrate types
  • The benefits of specifying self-leveling underlayment and cement-based patching and leveling compounds for resilient tile and stone flooring products
  • The performance and cost efficiencies inherent in using self-leveling underlayment materials
