Sikafloor® MultiDur EB-12 ECC
Sikafloor® MultiDur EB-12 ECC is a 2-part epoxy coloured resin based floor coating system that can provide a hard wearing, seamless, low maintenance, slip resistant gloss finish when broadcast with different aggregate grades on damp substrates. For medium - heavy wear conditions. Thickness 2.0 – 4.0 mm. Internal use.
- Seamless
- Good chemical and mechanical resistance
- Easy application
- Waterproof
- Gloss finish
- Easy cleanability
- Low maintenance
- Good bond to green or hardened damp/dry concrete
Usage
- On concrete and cementitious screeds with normal up to medium heavy wear e.g. storage and assembly halls, maintenance workshops, garages and loading ramps.
- On multi-storey and underground car park decks and for wet process areas, e.g. beverage and food industry

Application
Ambient Air Temperature
+10 °C min / +30 °C max
Relative Air Humidity
80 % r.h. max.
Dew Point
Beware of condensation!
The substrate and uncured floor temperature must be at least 3 °C above the dew point to reduce the risk of condensation or blooming on the floor finish.
Substrate Temperature
+10 °C min. / +30 °C max.
Substrate Moisture Content
Can be applied on green or damp concrete, with no standing water.
Although the system can be applied onto green concrete surfaces (> 24 hours), it is advised to allow at least 3 days for early concrete shrinkage to occur in order to prevent shrinkage cracks from appearing on the wearing surface.
Waiting Time / Overcoating
Before applying Sikafloor®-81 EpoCem® on Sikafloor®-80 EpoCem® Primer allow:
| Substrate Temperature | Minimum | Maximum |
| +10 °C | 12 hours | 24 hours |
| +20 °C | 6 hours | 12 hours |
| +30 °C | 4 hours | 6 hours |
Sikafloor®-81 EpoCem® can be overcoated with vapour impermeable coatings when the surface humidity falls below 4%
Not earlier than :
| Substrate Temperature | Waiting Time |
| +10 °C | 2 days |
| +20 °C | 1 day |
| +30 °C | 1 day |
Applied Product Ready for Use
| Temperature | Foot Traffic | Light Traffic | Full Cure |
| +10 °C | ~ 72 hours | ~ 6 days | ~ 10 days |
| +20 °C | ~ 24 hours | ~ 4 days | ~ 7 days |
| +30 °C | ~ 18 hours | ~ 2 days | ~ 5 days |
