Pretreatment

The surfaces are cleaned of impurities that can 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:

STEEL SURFACES: Remove scale and rust by sandblasting to degree of cleanliness SA 2½ (standard ISO 8501-1). The profile of the sandblasted surface must be rough (reference comparator "G") ISO 8503-2 (G). The surface of thin sheets can be prepared by e.g. phosphating.

OLD PAINTED SURFACES SUITABLE FOR OVERCOATING: Impurities that can be harmful to the application of the paint (eg grease and salts) are removed. The surfaces must be dry and clean. Old, painted surfaces that have exceeded the maximum paintability must be roughened. Pre-treatment of damaged parts is carried out according to the requirements for surface and maintenance painting.

ZINC SURFACES: Hot-dip galvanized steel structures that are exposed to the weather can be painted if the surface is sandblasted (SaS), so that the entire surface becomes matt. Suitable blowing agents are, for example, aluminum oxide and natural sand. In h.t. According to ISO standard 12944-5, it is not recommended to paint galvanized structures that are to be immersed in water or soil. When painting such objects, contact Teknos separately.

ALUMINUM SURFACES: The surfaces are treated with a suitable cleaning agent. Surfaces exposed to the weather are roughened with sandblasting (AISaS) or sanding. 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.

All equipment that will be in direct contact with the paint must be cleaned with a thinner suitable for the paint before use.

Application Mixing of components: Take into account the pot life of the mixture when calculating the amount to be mixed at one time. The base is stirred homogeneously before the components are mixed. Before application, base and hardener are mixed in the right ratio. Carefully stir down to the bottom of the container. The mixing time must be at least 5 minutes. Inadequate stirring or incorrect mixing ratio results in insufficient curing and poorer film properties
