Sikagard®-75 EpoCem®

Sikagard®-75 EpoCem®
SUPERFINE EPOXY CEMENT SEALING MORTAR AND TEMPORARY MOISTURE BARRIER
DESCRIPTION
Sikagard®-75 EpoCem® is a 3-component epoxymodified cementitious sealing and levelling mortar,
suitable for application to most mineral based substrates.
Its specific balanced formulation ensures that the
properties of the hydrated cement are both complemented and enhanced by the integral epoxy mortar.
USES
Used on both vertical and horizontal surfaces of concrete, mortar or stone, the thixotropic mortar can be
applied as a thin layer coating,
0.5-2 mm thick or as a scraping/ levelling mortar to
fill in blow holes, shallow honey combing and other
surface irregularities. Its ability to provide a temporary moisture barrier provides and ideal substrate for
subsequent epoxy coatings.
CHARACTERISTICS / ADVANTAGES
Waterproof yet permeable to water vapour, allows
the substrate to “breath”
▪
▪ Excellent adhesion to dry or damp substrates
Fast and easy to apply to sound prepared substrates
▪
▪ Solvent free and virtually odourless
Ideal surface preparation with the minimum of
delay for the subsequent application of other appropriate Sika epoxy products
▪
▪ High abrasion resistance
▪ Free of chloride
▪ Similar thermal and elastic properties to concrete
▪ Good adhesion after long-term water immersion
▪ Suitable for interior or exterior use
