SURFACE PREPARATION: Remove oil and grease etc. thoroughly with suitable detergent. Remove salts and other contaminants
by high pressure fresh water cleaning.
Abrasive blasting to Sa 2½ (ISO 8501-1:2007), SSPC-SP 10/ NACE No. 2, with a sharp-edged surface
profile corresponding to Rugotest No. 3, BN10a-b, Keane-Tator Comparator, 3.0 G/S, 2-3 S, or ISO
Comparator, Medium (G).
APPLICATION CONDITIONS: Use only where application and curing can proceed at temperatures above: -10°C/14°F. The
temperature of the surface must also be above these limits. The temperature of paint itself should be
15°C/59°F or above. Apply only on a dry and clean surface with a temperature above the dew point to
avoid condensation. In confined spaces provide adequate ventilation during application and drying.
SUBSEQUENT COAT: According to specification.
REMARKS: Note: If used as anticorrosive protection under insulation of high temperature equipment it is very
important that NO moisture can penetrate during slow-down periods. This is to avoid the risk of "wet
corrosion" when the temperature rises.
Stirring: Before mixing with the curing agent stir the base thoroughly in order to redisperse any possible settling
after storage. After mixing it is equally important to maintain stirring to keep the wet paint as a
homogeneous mixture.
This is specifically important in case of a high level of thinning and/or long break in application, where
the risk of settlement of zinc particles is the highest.
Film thicknesses/thinning: May be specified in another film thickness than indicated depending on purpose and area of use. This
will alter spreading rate and may influence drying time and overcoating interval. Normal range dry is:
50-75 micron/2-3 mils
(The dry film thickness range does not take into account the correction factors for rough surfaces as
listed in ISO 19840).
Overcoating: Overcoating intervals related to later conditions of exposure: If the maximum overcoating interval is
exceeded, roughening of the surface is necessary to ensure intercoat adhesion.
Before overcoating after exposure in contaminated environment, clean the surface thoroughly with high
pressure fresh water hosing and allow drying.
