Surface preparation
All surfaces should be clean, dry and free from contamination. The surface could be assessed and treated in accordance with ISO 8504.
Bare steel
Cleanliness: Blast cleaning to Sa 2½ (ISO 8501-1:2007) Roughness using abrasive suitable to achieve grade find to medium G 930-85 um, Ry5) (ISO 8503-2)
Other surfaces
The coating may be used on other substrates. Please contact your Berger international office for more information.
Condition during application
The temperature of the substrate should be minimum 3°C above the dew point of the air, temperature and relative humidity measured in the vicinity of the substrate. Good ventilation is usually required in confined areas to ensure correct drying.
Application methods
Spray : – Use airless spray or conventional spray
Brush : – Recommended for stripe coating and small areas ,care must be taken to achieve the
Specified dry film thickness
Roller : – May be use for small areas but not recommended for first primer coat. However when using
Roller application care must be taken to apply sufficient material order to achieve the
Specified dry film thickness.
