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 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.
Consumption

Consumption

Theoretical material-consumption/VOC without loss for medium dry film thickness:

Dry film thickness

80 μm

Wet film thickness

140 μm

Consumption~0.225 kg/m2
VOC~47 g/m2

With SikaCor® EG Phosphat Rapid up to 120 µm dry film thickness per application can be achieved by airless spraying.
Application steps

SURFACE PREPARATION

Steel:
Blast cleaning to Sa 2 ½ according to DIN EN ISO 12944-4.
Free from dirt, oil and grease.

For contaminated and weathered surfaces 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 clothing.

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°
