Sikafloor® EpoCem® ES-14 AP
Epoxy-cement hybrid self-smoothing floor screed and smooth finish flooring system
Sikafloor® EpoCem® ES-14 AP is an epoxy-cement hybrid, fine textured screed followed by epoxy scratch coat for a smooth finish industrial flooring system. It provides a hard wearing, seamless, low maintenance smooth wearing layer. Thickness 2.0–3.0 mm. Internal use.
- Can be top coated with resin based floors after 24 hours (at +20 °C / 75 % r.h.)
- Impervious to liquids but permeable to water vapour
- Prevents osmotic blistering of resin based coatings over damp substrates
- Economical and fast, easy application
- Water-based, solvent-free and odourless
- Good levelling properties
- Frost and de-icing salt resistant
- Good chemical resistance
- Thermal expansion properties similar to concrete
- Excellent bond to green or hardened concrete whether damp or dry
- Excellent early and final mechanical strengths
- Excellent resistance to water and oils
- Ideal preparation for smooth surface finishes
- For internal use
- Does not corrode reinforcement steel
- Class R4 of EN 1504-3
System Structure
Usage
As a Temporary Moisture Barrier (TMB) (min. 2 mm thick) under epoxy, polyurethane and PMMA resin floors, over high moisture content substrates, even green concrete. As a self-smoothing screed for:- Levelling or patching horizontal concrete surfaces, in new work or repairs, particularly in aggressive chemical environments
- Floor topping on non-ventilated damp substrates without particular aesthetic requirements
- Levelling layer under epoxy, polyurethane and PMMA floor coatings / screeds, tiles, sheet floors, carpets or wooden floors
- Repair and maintenance of monolithic and vacuum concrete floors
- Under epoxy, polyurethane and PMMA floor coatings / screeds for multi-storey and underground car parks, maintenance hangars and for wet process areas, e.g., beverage and food industry for areas where slip resistance and easy cleanability is required

Application
Ambient air temperature
+10 °C min. / +35 °C max.
Relative air humidity
80 % max.
Dew point
Beware of condensation.
The substrate and uncured applied floor material must be at least +3 °C above dew point to reduce the risk of condensation or blooming on the surface of the applied product. Be aware that the substrate temperature may be lower than the ambient temperature.
Substrate temperature
+10 °C min. / +35 °C max.
Substrate moisture content
Can be installed on substrates with a moisture content of ≤ 6 % (measured by Sika®-Tramex meter). The substrate must be visibly dry with no standing water and have a tensile strength of ≥ 1.5 N/mm2.
Can also be applied on green or damp concrete with no standing water. Although the system can be applied onto green concrete surfaces (> 7 days), 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 | 3 days |
| +20 °C | 06 hours | 2 days |
| +30 °C | 04 hours | 1 day |
Sikafloor®-81 EpoCem® can be overcoated with vapour tight scratch coat when the surface moisture falls below 4 %. Before applying Sikafloor®-161 HC/-264 HC N on Sikafloor®-81 EpoCem® allow:
| Substrate temperature | Minimum |
| +10 °C | 2 days |
| +20 °C | 1 day |
| +30 °C | 1 day |
Times are approximate and will be affected by changing ambient conditions particularly temperature and relative humidity.
