Application
Mixing Ratio
Part A : B : C = 1 : 1 : 4 (packaging size = 5 : 5 : 20) by weight
Mix full units only.
Ambient Air Temperature
+10 °C min. / +35 °C max
Layer Thickness
Scratch coat: 0.5–1.5 mm
Base- and wear coat: 3–6 mm
Relative Air Humidity
80 % max
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 other disturbance of the surface on the floor finish.
Substrate Temperature
+10 °C min. / +35 ºC max
Substrate Moisture Content
Can be installed on substrates with higher moisture content (6% checked by Tramex). The substrate needs to be visibly dry and have adequate pull-off strength min 1.5 N/mm2 No ponding water. Check rising moisture.
Pot Life
| Temperatures | Time |
| +10 °C | ~ 35 - 40 minutes |
| +20 °C | ~ 22 - 25 minutes |
| +30 °C | ~ 15 – 18 minutes |
| +35 °C | ~ 12 - 15 minutes |
Curing Time
Before overcoating Sikafloor®-210 PurCem®
| Substrate temperature | Minimum | Maximum |
| +10 °C | 24 hours | 72 hours |
| +20 °C | 24 hours | 48 hours |
| +30 °C | 12 hours | 24 hours |
| +35 °C | 12 hours | 24 hours |
Times are approximate and will be affected be changing ambient and substrate conditions, particularly temperature and relative humidity.
If used other primers than Scratch Coat refer the Technical Data Sheet of the respective product. Make sure that the primer and the scratch coat layer is fully cured before application of Sikafloor® PurCem® previous layer.
Consumption
~ 1.9 kg/m2/mm
MIXING
Mix first the component A (pigmented liquid) thoroughly in the pail 10 – 15 sec. Then add component B (brown liquid) into A and mix together for 15 - 30 sec. using a stirrer in a low speed electric drill until homogenous mixture. Then add component C to A+B mixing simultaneously with larger mixer. When the bag of component C is empty, continue mixing further 3 min depending on the temperature and the mixer efficiency.
APPLICATION
Prior to application, confirm substrate moisture content, relative humidity and dew point. As a scratch coat Sikafloor®-210 PurCem® can be applied using a steel trowel. As a body coat Sikafloor®-210 PurCem® can be applied using a toothed trowel or pin screed, to the desired thickness, or a steel trowel. Remove air with a spike roller.
For further details please refer to the related system data sheet.
CLEANING OF TOOLS
Clean all tools and application equipment with Thinner C immediately after use. Hardened / cured material can only be mechanically removed.
