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.

Uses

• As a levelling layer over concrete and mortars in 0.5–3 mm 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 requiring dry substrates, for a lasting solution.
• As a pore sealer for the reprofiling, 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)
  * See Notes on Application / Limitations
