Products Substrate-Preparation DU CEM


Normal-setting and fast-drying hydraulic binder for interior and exterior use


Dubond's DU CEM is a specially engineered product to be mixed with aggregates of particle size from 0 to 8 mm and water that develops hydro elasticity at a fast pace and unparallel dimensional stability to all kind of Screed such as P.C.C., R.C.C the continuous hygrometric balance generated by it,makes a fast and complete laying of ceramic tiles, possible within 24 hours and parquet in 5 days. The high resistance binding of screeds happens to the heat radiant slabs. And the unique features of DU CEM screed are Normal Setting, Rapid Drying, High Thermal Conduction and Compensated Shrinkages. There after the Usage of ceramic, Porcelain, Vitrified, Homogenous tiles, natural stones, resilient materials and parquet to such a ready base, possible in least time.


  • Suitable for floating or bonded screeds in both interiors and exteriors. Ideal for fast laying of:
  • Ceramic tiles after 24 hours
  • Natural stone after 3 days
  • Parquet, PVC,linoleum, carpet after 2 weeks
  • Also suitable for screeds with incorporated heating coils.
