Application
Mixing ratio
| Components A : B |
| By weight | 90 : 10 |
| By volume | 4.6 : 1 |
Material temperature
Min. + 5°C
Relative air 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.
Pot Life
| At + 10°C | ~12 h |
| At + 20°C | ~8 h |

Waiting time to overcoating
Min. until drying stage 6 is achieved
Max. 1 year
In case of longer waiting times please contact Sika.
Make sure that all contamination is removed before overcoating with top coats (see surface preparation).
Thinner
Sika® Thinner EG
If necessary max. 5 % Sika® Thinner EG may be added to adapt the viscosity.
In case of weldable shop primer add approx. 18 % b.w. Sika® Thinner EG.
Drying time
Final drying time
Depending on film thickness and temperature full hardness is achieved after 1 - 2 weeks. Tests of the completed coating system should only be carried out after final curing.

| Dry film thickness 80 µm | |
| + 5°C after | 10 h |
| + 10°C after | 7 h |
| + 20°C after | 3.5 h |
| + 40°C after | 25 min |
| + 80°C after | 15 min |
Surface temperature
Min. + 5°C
Consumption
Theoretical material-consumption without loss for medium dry film thickness:
| Dry film thickness | 80 µm |
| Wet film thickness | 129 µm |
| Consumption | ~0.206 kg/m2 |
SUBSTRATE PREPARATION
Ensure surfaces to be coated are clean, dry and free from all surface contamination such as oil, grease, dirt and corrosion products to achieve satisfactory adhesion. For contaminated and weathered surfaces we recommend to clean with SikaCor® Wash. Steel surfaces shall be blast-cleaned to Sa 2½ according to ISO 8501-1 (ISO 12944-4).
MIXING
Stir component A very thoroughly using an electric mixer (start slowly, then increase up to approx. 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. During mixing and handling of the materials always wear protective goggles, suitable gloves and other protective clothings.
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 min. 180 bar
▪ Nozzle size 0.38 - 0.53 mm (0.015 - 0.021 inch)
▪ Spraying angle 40° - 80°
