HINTS OF APPLICATION
PREPARATION OF MATERIAL Coating materials:
Stir Component A very thoroughly using an electric stirrer. Add component B and mix both components very thoroughly (including sides and bottom of the container).
Sika Cable Flex-1 and Sika Cable Flex-2:
Stir component A slowly by means of an electric stirrer (max. 300 rpm), sub- sequently add hardener in the correct mixing proportion and mix intensively again using an electric stirrer (300 - 500 rpm) until a homogeneous mixture is achieved (min. 3 minutes). Take care that no air is entrapped.
APPLICATION METHOD Coating materials:
The method of application has a major effect on achieving uniform thickness and appearance. Adding solvents reduces the sag resistance and the dry film thickness. In case of application by roller or brush, additional applications may become necessary to achieve the required coating thickness, depending on type of construction, site conditions, colour shade etc. Prior to major coating operations a test application on site may be useful to ensure the selected application method will provide the requested results.
By brush and roller:
According to ZTV-KOR „Cables“ brushing is the preferred application method. Where light and intense colour shades are applied, a second top coat might become necessary.
Sika Cable Flex-1 and Sika Cable Flex-2:
The application technique depends on the design features of the project.
Steel has to be primed with Sika Cable FE Primer, galvanized steel with Sika Cable ZN Primer.
DO NOT THIN Sika Cable Flex-1 and Sika Cable Flex-2.
APPLICATION CONDITIONS Min. + 5 °C (material and surface)
Relative humidity: Max. 85 %, except the surface temperature is significantly higher than the dew point temperature, it shall be at least 3 K above dew point.
If necessary max. 5% Sika Thinner EG may be added to adapt the viscosity.
