KORRO AQUA 2741

Remove from the surfaces any contaminants that might be detrimental to surface preparation and application. Remove also water-soluble salts by using appropriate methods. The surfaces are prepared according to the different materials as follows: STEEL SURFACES: Remove mill scale and rust by blast cleaning to preparation grade Sa 2½ (standard ISO 8501-1). Additional instructive information for surface preparation can be found in standards EN ISO 12944-4 and ISO 8501-2.

Stir thoroughly before use. Apply as evenly as possible. The best result is achieved by an automatic airless spray. Suitable airless nozzle size 0.015 - 0.021".

The surface to be treated must be dry. During the application and drying period the temperature of the ambient air, the surface and the product shall be above +15°C and the relative air humidity below 70%. Additionally, the temperature of the surface to be treated and the product must be at least +3°C above the dew point of the ambient air. Especially when applying with a spray the relative air humidity should be above 30% to avoid the onset of the drying process to be too fast. Surface temperature, film thickness, drying temperature and ventilation affect the drying of the paint. The paint is dry when all water has evaporated from the paint film. It is essential that all painted surfaces have sufficient ventilation. If the painted surface will be exposed to weathering, moisture or low temperatures (below +10°C) thick paint films are to be avoided and the last coat must be allowed to dry for at least 24 hours (at +23°C) before exposure. Low temperatures and insufficient ventilation slow down the drying process.

The storage stability is shown on the label. Store in a cool place and in tightly closed containers. Do not transport or store at temperatures below 0°C. Must not freeze.
