Thinner
Sika® Thinner P
If necessary maximum 5 % Sika® Thinner P may be added to adapt the viscosity.
Product Temperature
Min. +5 °C
Relative Air Humidity
Maximum 85 %, except the surface temperature is significantly higher than the dew point temperature, it shall be at least 3 K above dew point.
The surface must be dry and free from ice.

Pot Life
| At +10 °C | ~8 h |
| At +20 °C | ~6 h |
| At +30 °C | ~3 h |
Drying Stage 6
Drying stage 6 and waiting time between coats:
| Dry film thickness 80 μm | |
| 0 °C after | 48 h |
| +5 °C after | 24 h |
| +10 °C after | 18 h |
| +15 °C after | 10 h |
| +20 °C after | 8 h |
| +25 °C after | 6 h |
| +30 °C after | 4 h |
Drying time
Final drying time
The full hardness is achieved within approximately 7 days at +20 °C. 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 | 50 μm | 80 μm |
| Wet film thickness | 90 μm | 145 μm |
| Consumption | ~0.115 kg/m2 | ~0.185 kg/m2 |
| VOC | ~36.0 g/m2 | ~57.6 g/m2 |
These figures are theoretical and do not allow for any additional material due to surface colour, surface porosity and surface profile variations in level and wastage etc.
SURFACE PREPARATION
Steel:
Blast cleaning to Sa 2 ½ according to ISO 12944, part 4.
Free from dirt, oil and grease.
Hot dip galvanized steel, stainless steel and aluminium:
Free from dirt, oil, grease and corrosion products.
In case of exposure to permanent condensation the surfaces must be slightly sweep blasted with a ferrite-free blasting abrasive.
For 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. 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 or roller
Airless-Spraying:
- Pressure minimum 150 bar
- Nozzle size 0.38 - 0.53 mm (0.015 - 0.021 inch)
- Spraying angle 40° - 80°
