TEKNOLAC PRIMER 100

Remove from the surfaces any contaminants that might be detrimental to surface preparation and application. Before cleaning of surface, it is recommended to wash it with water with addition of OLICLEAN 123 and then rinse with fresh water. STEEL SURFACES: Remove mill scale and rust by blast-cleaning to preparation grade Sa 2½ or Sa 2 or by treating mechanically to preparation grade St 3 (ISO 8501-1). The preparation grade is chosen by the object and current corrosivity category. Roughening the surface of thin-plate improves the adhesion of the paint to the substrate. ALUMINIUM SURFACES: Treat the surfaces with RENSA STEEL washing agent for galvanized surfaces. Surfaces that are exposed to weathering are also roughened up with sweep blast-cleaning (AlSaS) or sanding. OLD PAINTED SURFACES SUITABLE FOR OVERCOATING: Any impurities that might be detrimental to the application of paint (e.g. grease and salts) are removed. The surfaces must be dry and clean. Old, painted surfaces that have exceeded the maximum overcoating time are to be roughened as well. Damaged parts are prepared in accordance with the requirements of the substrate and the maintenance coating. The place and time of the preparation are to be chosen so that the prepared surface will not get dirty or damp before the subsequent treatment. Additional instructive information for surface preparation can be found in standards EN ISO 12944-4 and ISO 8501-2.

Stir thoroughly before use. Apply by airless spray, brush, roller (for small areas only) or conventional spray. Suitable airless nozzle size 0.013 - 0.015".

The surface to be treated has to be dry. During the application and drying period the temperature of the ambient air, the surface and the product shall be above +5°C and the relative air humidity below 80%. 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.

The storage stability is shown on the label. Must be stored tightly closed and kept cool.
