Waiting Time / Overcoating
Minimum waiting time until drying stage 6 is achieved to unlimited maximum time.
Prior to further applications possible contamination must be removed (see page 3 surface preparation).
Drying time
Final drying time
Depending on film thickness and temperature full hardness is achieved after 1 to 2 weeks. Tests of the completed coating system should only be carried out after final curing.
Consumption
Theoretical material-consumption/VOC without loss for medium dry film thickness:
Dry film thickness | 60 μm | 80 μm |
| Wet film thickness | 100 μm | 130 μm |
| Consumption | ~0.130 kg/m² | ~0.170 kg/m² |
| VOC | ~33.2 g/m² | ~44.3 g/m² |
SURFACE PREPARATION
Steel:
Blast cleaning to Sa 2 ½ according to ISO 12944, part 4.
Free from dirt, oil and grease.
Galvanized steel, stainless steel and aluminium:
Free from dirt, oil, grease and corrosion products.
In case of permanent immersion and condensation the surfaces must be slightly sweep blasted with non-ferrous abrasives.
Contaminated surfaces for example galvanized or primed areas we recommend to clean with SikaCor® Wash.
MIXING
Stir component A very thoroughly using an electric mixer (start slowly, then increase up to approximately 300 rpm). Add component B carefully and mix both components very thoroughly (including sides and bottom of the container). Mix for at least 3 minutes until a homogeneous mixture is achieved. Fill mixed material into clean container and mix again shortly as described above.
APPLICATION
The method of application has a major effect on achieving uniform thickness and appearance. Spray application will give the best results. The indicated dry film thickness is easily achieved by airless spray. 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
Conventional high pressure spraying:
- Nozzle size 1.5 - 2.5 mm
- Pressure 3 - 5 bar
- Oil and water trap is compulsory
Airless-spraying:
- Pressure minimum 180 bar
- Nozzle size 0.38 - 0.53 mm (0.015 - 0.021 inch)
- Spraying angle 40° - 80°
CLEANING OF EQUIPMENT
SikaCor® Cleaner
Spraying equipment must be rinsed with Sika® Thinner EG before using SikaCor® EG-5.
