Waiting time to overcoating
Min.: Until drying stage 6 is achieved.
Higher layer thicknesses, but also lower temperatures than specified, lead to longer drying times. The overcoating intervals can be delayed and may need to be determined on site.
Max.: 1 year
In case of longer waiting times please contact us.
Prior to further applications: After a waiting period or after exposure to weathering, all possible contamination must be removed from the surface before the subsequent coating is applied.
Drying time
Final drying time
Depending on layer thickness and temperature final hardness is achievedwithin a few days.
Tests of the completed coat should only be carried out after final curing.
Consumption
Theoretical material-consumption/VOC without loss for medium dry film thickness:
Dry film thickness | 80 μm |
Wet film thickness | 130 μm |
Consumption | ~0.205 kg/m2 |
VOC | ~41.3 g/m2 |
SURFACE PREPARATION
Steel:
Blast cleaning to Sa 2 ½ according to ISO 12944-4.
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 permanent immersion and condensation the surfaces must be slightly sweep blasted with a ferrite-free blasting abrasive.
For contaminated and weathered surfaces e.g. 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 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:
- Apply undiluted
Airless-spraying:
- Pressure min. 180 bar
- Nozzle size 0.38 - 0.53 mm (0.015 - 0.021 inch)
- Spraying angle 40° - 80°
