Sikafloor® MultiDur WS-10 ECC
Sikafloor® MultiDur WS-10 ECC is a 2-part, water based epoxy coloured resin floor coating system that can provide a hard wearing, seamless, low maintenance, slip resistant semi-gloss finish on damp substrates. For normal up to heavy wear conditions. Thickness 2,0–4,0 mm. Internal use.
- Seamless
- Good chemical and mechanical resistance
- Temporary moisture barrier
- Easy application
- Water vapour permeable
- Water thinnable
- Odourless
- Easy cleanability
- Low maintenance
- Good bond to green or hardened damp/dry concrete
Usage
- As a temporary moisture barrier (TMB) on cementitious substrates
- On concrete and cementitious screeds for normal up to medium heavy wear e.g. storage and assembly halls, maintenance workshops, garages
- For production, processing areas, warehouses, car park decks.

Application
Ambient Air Temperature
+10 °C min. / +30 °C max.
Relative Air Humidity
75 % r.h. maximum. Adequate fresh air ventilation must be provided to remove excess moisture during curing.
Dew Point
Beware of condensation!
The substrate and uncured floor must be at least 3 °C above 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 |
Before applying Sikafloor®-2540 W on Sikafloor®-2540 W allow:
| Substrate temperature | Minimum | Maximum |
| +10 °C | 48 hours | 7 days |
| +20 °C | 20 hours | 6 days |
| +30 °C | 10 hours | 3 days |
Times are approximate and will be affected by changing ambient conditions particularly temperature and relative humidity.
If relative air humidity is ≥ 75 % the waiting time is increased by at least 24 hours.
Applied Product Ready for Use
