Application

Application Information

Mixing Ratio

Part A : B : C = 1 : 1 : 1.15 (packaging size = 1.85 : 1.85 : 2.1) by weight
Mix full units only.

Ambient Air Temperature

+10 °C min. / +35 °C max.

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 °C max

Substrate Moisture Content

Can be installed on substrates with increased 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.

Application steps

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 top coat Sikafloor®-310 PurCem® can be applied using a soft foam rubber squeegee and back roll with a medium pile 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.
