Consumption

Consumption

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

Dry film thickness80 μm

Apart from small areas the dry film thickness should not exceed 150 μm per layer.
Application steps

SURFACE PREPARATION

Steel:

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

Free from dirt, oil and grease.

Surface profile "medium (G)" according to ISO 8503-2, roughness RZ ≥ 50 μm.

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 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

Airless-Spraying:

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