Description

Durex Dur-A-Top SLU 25 is a cementitious self-leveling underlayment, well-balanced blend of selected aggregates and various types of cements to produce a pourable or pumpable cement compound which will self-level after screeding to the desired level of coverage. It is used in conjunction with Durex Dur-A-Top Acrylic Primer.

Advantages
  • Fast setting (can be walked on in  12 hours depending on Thickness and site conditions)
  • Excellent adhesion when used in conjunction with Durex Dur-A-Top Acrylic Primer.
  • Mix as required (no waste)
  • Minimum skill required for application
  • Mix as required (no waste).
  • Minimum skill required for application.
