Application steps

SURFACE PREPARATION

Steel:

Blast-cleaning to Sa 2 ½ according to ISO 12944-4.

Free from dirt, oil and grease, primed (see "System", page 2).

Hot dip galvanized steel, stainless steel, 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 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 or roller:

  • To achieve the dry film thickness an additional application may be necessary


Airless-spraying:

  • Pressure min. 180 bar
  • Nozzle size 0.38 - 0.53 mm (0.015 - 0.021 inch)
  • Spraying angle 40° - 80°
