Performance Guide

WeatherabilitySome chalking and yellowing may occur on exterior exposure if not topcoated with a suitable UV resistant coating, but this will not detract from the high performance protective properties of this coating.
Water ResistanceExcellent resistance to fresh and salt water. Factory packaged colours (excluding those containing aluminium) are suitable for immersion.
Abrasion ResistanceGood abrasion resistance when fully cured.
Solvent ResistanceResists splash and spillage of most hydrocarbon solvents, refined petroleum products and most common alcohols.
Acid ResistanceSuitable for splash and spillage of weak solutions of inorganic and organic acids. Aluminium containing colours are not suitable for acidic conditions.
Alkaline ResistanceExcellent resistance to splash and spillage of strong alkali. Aluminium containing colours are not suitable for alkaline conditions.
Salt ResistanceExcellent resistance to neutral and alkaline salt solutions. Aluminium containing colours are not suitable for alkaline conditions.

Surface Preparation

Ensure surface is sound and has been cleaned and prepared according to coating specification. Remove rust by power tool cleaning and spot prime as soon as practical.


Durebild® STE is particuarly suitable for the maintenance of all types of previously painted substrates, including steel, due to its exceptional wetting and adhesion properties. Durebild® STE is used for the protection of all types of steel structures, particularly where surface preparation is limited to power tool cleaning methods. Durebild® STE does not need to be topcoated in internal environments as it is extremely durable and is available in Dulux Colour Specifier colours. Durebild® STE is also suitable for fresh and salt-water immersion when untinted.
