Smoothing & Levelling Mortars for Cooling Towers

Before a protective coating can be added to the cooling tower or chimney, the surface must be uniform and free of defects. Adequate surface preparation comes in the form of smoothing mortars.

Sikagard® 720 EpoCem®

Product Description

Sikagard®-720 EpoCem® is a three part, epoxy modified cementitious, thixotropic, fine textured mortar for levelling and finishing of concrete, mortar or stone surfaces. 



  • As a levelling layer over concrete and mortars in 0.5-3mm on vertical or horizontal surfaces.
  • Application in new works or damaged concrete in aggressive chemical environments 
  • Application over high moisture content substrates, even green concrete 
  • As a Temporary Moisture Barrier (TMB) (min. 2 mm thick) allowing the application of Epoxy, Polyurethane and PMMA* resin coatings or floors requiring dry substrates for a lasting solution. 
  • As a pore sealer for the re-profiling, smoothing and levelling of concrete surfaces 
  • Suitable for moisture control (Principle 2, method 2.3 of EN 1504-9) 
  • Suitable for restoration work (Principle 3, method 3.1 and 3.3 of EN 1504-9).
  • Suitable for physical resistance (Principle 5, method 5.1 of EN 1504-9) 
  • Suitable for preserving or restoring passivity (Principle 7, method 7.1 and 7.2 of EN 1504-9) 
  • Suitable for increasing resistivity (Principle 8, method 8.3 of EN 1504-9)
