Packaging
Part A | 24,9 kg containers |
Part B | 5,1 kg containers |
Part A+B | 30 kg ready to mix units |
Colour
Resin - part A | coloured, liquid |
Hardener - part B | transparent, liquid |
Almost unlimited choice of colour shades.
Due to the nature of carbon fibres providing the conductivity, it is not possible to achieve exact colour matching. With very bright colours (such as yellow and orange), this effect is increased. Under direct sun light there may be some discolouration and colour variation, this has no influence on the function and performance of the coating.

Consumption
| Self-smoothing wearing course (Film thickness ~ 1.5 mm) | Sikafloor®-269 ECF CR filled with Sikadur® 501 IN | Maximum 2.0 kg/m² Binder + Sikadur® 501 IN. Depending on the temperature the filling grade varies from: 1 : 0.1 pbw (1.8 + 0.2 kg/m²) 1 : 0.2 pbw (1.6 + 0.4 kg/m²) |
These figures are theoretical and does not allow for any additional material required due to surface porosity, surface profile, variations in level and wastage etc.
For further details please refer to the system related System Data Sheet.
MIXING
Prior to mixing, stir part A mechanically. When all of part B has been added to part A, mix continuously for 2 minutes until a uniform mix has been achieved. When parts A and B have been mixed, add Sikadur® 501 IN and mix for a further 2 minutes until a uniform mix has been achieved. To ensure thorough mixing pour materials into another container and mix again to achieve a consistent mix. Over mixing must be avoided to minimise air entrainment. Sikafloor®-269 ECF CR must be thoroughly mixed using a low speed electric stirrer (300 - 400 rpm) or other suitable equipment.
APPLICATION
Sikafloor®-269 ECF CR is poured, spread evenly by means of a serrated trowel e.g. Large-Surface Scraper No. 656, Toothed blades No. 25 (www.polyplan.com). After spreading the material evenly, turn the serrated trowel and smooth the surface in order to achieve an aesthetically higher grade of finish. Roll immediately (within max. 10 minutes of application) in two directions with a steel spiked roller to ensure even thickness and to remove entrapped air. To obtain the highest level of aesthetic finish, spike roll in two directions at a 90 degree angle, passing only once in each direction.
CLEANING OF TOOLS
Clean all tools and application equipment with Thinner C immediately after use. Hardened and/or cured material can only be removed mechanically.
