Technical data sheet
Surface preparation
Remove from the surface any contaminants that might be detrimental to surface
preparation and coating. Remove also water-soluable salts by using appropriate
methods. The surface should be prepared as follows:
STEEL SURFACES: Remove mill scale and rust by blast cleaning to preparation
grade Sa 2½ (standard ISO 8501-1). Roughening the surface of thin-plate
improves the adhesion of the paint to the substrate.
ZINC SURFACES: Hot-dip-galvanized steel structures that are exposed to
atmospheric corrosion can be painted if the surfaces are sweep blast-cleaned
(SaS) till matt all over. Suitable cleaning agents are, e.g. aluminium oxide and
natural sand. It is not recommended to paint galvanized objects that are
subjected to immersion strain.
It is recommended that new zinc-coated thin-plate structures are treated with
sweep blast-cleaning (SaS). Surfaces that have been weathered to matt can be
treated also with PELTIPESU Cleaning Agent.
ALUMINIUM SURFACES: Treat the surfaces with PELTIPESU Cleaning Agent.
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 to
be removed. The surface must be dry and clean. Old, painted surfaces that have
exceeded the maximum overcoating time are to be roughend as well. Damaged
parts are prepared in accordance with the requirements of the substrate and the
maintenance coating.
Time and place of preparation should be so chosen, that the prepared surface
will not get dirty or damp before further surface treatment.
