3-part cement and epoxy combination pore filler and leveling mortar Sikagard-720 EpoCem is a 3-part, epoxy modified, cementitious, fine textured mortar for levelling and finishing concrete, mortar or stone surfaces. - Improved chemical resistance compared to PCC mortars
- Good protection of concrete in aggressive environments
- Waterproof
- Application range 0.5-3mm on vertical and horizontal surfaces
- Good adhesion to damp or dry concrete
- Fast overcoating of Sika resin based finish products
- Good surface finishing
- Does not require overcoating
- Manual and machine application (wet spray technique)

21 kg unit Waiting Time / Overcoating Once Sikagard-720 EpoCem is tack free it is possible to apply vapour permeable resin finishes.
For the application of vapour tight resin finishes on Sikagard-720 EpoCem, allow the surface moisture to fall below 4 % and not earlier than: | Temperature | Time | | +10 °C | ~60 hours | | +20 °C | ~15 hours | | +30 °C | ~8 hours |
Times are approximate and will be affected by changing ambient conditions particularly temperature and relative humidity. Curing Treatment | Temperature | Full cure | | +10 °C | ~14 days | | +20 °C | ~7 days | | +30 °C | ~4 days |
Times are approximate and will be affected by changing ambient conditions particularly temperature and relative humidity. |
