SUBSTRATE PREPARATION

Ensure surfaces to be coated are clean, dry and free from all surface contamination such as oil, grease, dirt and corrosion products to achieve satisfactory adhesion.

For contaminated and weathered surfaces e.g. primed areas we recommend to clean with SikaCor® Wash.

Steel surfaces shall be blast-cleaned to Sa 2½ according to ISO 8501-1 (ISO 12944-4).

Hot-dip galvanized surfaces, copper, aluminium, hard PVC shall be prepared by degreasing.

Maintenance coatings: In case of well adhering old coating systems, careful cleaning is sufficient. Loose particles must be removed, corroded and defective areas must be prepared to PSa 2½, PMa or PSt 2 and patch-primed with Sika® CorroTop or SikaCor® Aktivprimer Rapid.

MIXING

Sika® CorroTop NEW and Sika® CorroTop EG NEW are supplied ready for use. Stir thoroughly prior to application.

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 - 2.0 mm
  • Pressure 3 - 5 bar


Airless-spraying:

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