Pretreatment The surfaces are cleaned of impurities that may be harmful for pretreatment and application. In addition, water-soluble salts are removed by suitable methods. The surfaces of the various materials are pre-treated as follows:
OLD PAINTED SURFACES SUITABLE FOR OVERCOATING: Impurities that can be harmful to the application of the paint (e.g. grease and salts) are removed. The surfaces must be dry and clean. Pre-treatment of damaged parts is carried out according to the requirements for surface and maintenance painting. Choose the place and time for the treatment, taking into account that the pre-treated surface does not become dirty or damp before the subsequent treatment.
Other instructions regarding pre-treatment of the surface can be found in the standards EN ISO 12944-4 and ISO 8501-2.

It is recommended that approx. 30 vol.% thinner: See chart in technical data sheet.
