Ambient Air Temperature
+10 °C min. / +35 °C max.
Layer Thickness
~25 μm per coat dry film thickness (dft)
Relative Air Humidity
85 % 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.
Substrate Temperature
+10 °C min. / +35 °C max.
Substrate Moisture Content
Can be applied on matt, damp concrete when overcoating with the Sikafloor® EpoCem® range.
Pot Life
Temperature | Time |
+10 °C | ~120 minutes |
+20 °C | ~90 minutes |
+30 °C | ~45 minutes |
Curing Time
Substrate temperature | Foot traffic |
+10 °C | ~12 hours |
+20 °C | ~6 hours |
+30 °C | ~4 hours |
No specific additional curing measures are required.
Times are approximate and will be affected by changing ambient conditions particularly temperature and relative humidity.
Waiting Time / Overcoating
Before applying Sikafloor®-81 EpoCem® / Sikafloor®-82 EpoCem® onto Sikafloor® EpoCem® Modul allow:
Substrate temperature | Minimum | Maximum |
+10 °C | 12 hours | 24 hours |
+20 °C | 4 hours | 12 hours |
+30 °C | 3 hours | 6 hours |
Times are approximate and will be affected by changing ambient conditions particularly temperature and relative humidity.
Consumption
1–2 coats × 0,2–0,3 kg/m2
These figures are theoretical and do not include for any additional material required due to surface porosity, surface profile, variation in level or wastage, etc.
EQUIPMENT
Mixing Tools
- Single paddle electric stirrer (300–400 rpm).
MIXING
Prior to mixing all parts, mix part A (resin) using a low speed single paddle electric stirrer. Add part B (hardener) to part A and mix part A + B continuously for 3.0 minutes until a uniform mix has been achieved. To ensure thorough mixing pour materials into a clean container and mix again for at least 1.0 minute to achieve a smooth consistent mix. Excessive mixing must be avoided to minimise air entrainment. During the final mixing stage, scrape down the sides and bottom of the mixing container with a straight edge trowel or spatula at least once to ensure complete mixing. Mix full units only. Mixing time for A+B = ~4.0 minutes
APPLICATION
Reference must be made to further documentation where applicable, such as relevant method statement, application manual and installation or working instructions.
Prior to application, confirm substrate moisture content, relative air humidity and dew point.
Pour mixed primer onto the prepared substrate and apply by brush, roller or squeegee then back roller in two directions at right angles to each other. Ensure a continuous, pore free coat covers the substrate. If necessary, apply two priming coats.
Confirm primer waiting /overcoating time has been achieved before applying subsequent products.
CLEANING OF TOOLS
Clean all tools and application equipment with water immediately after use. Hardened material can only be removed mechanically.
