Generally, a stress-related failure due to movement, aging, absorption and desorption of moisture and a lack of flexibility within the paint or coating film.

Low film thickness not covering rogue peaks of the surface profile beneath; also seen from metallic contamination of a painted or coated surface by grinding dust, for example.

Where a paint or coating delaminates from the surface below, either within the differing coats of material or from the substrate.

Failure of the paint or coating film to flow, commonly caused by poor application techniques or incorrect solvent blend.

The most common paint and coating defects originate not with the material itself, but with poor surface preparation and application techniques. This can be avoided by the use of a competent, experienced contractor. Contact us on 01274 721188 or email sales@kuegroup.com for all your surface preparation, painting and coating requirements.

Generally, two forms of blistering are noted: Osmotic – where the cause is associated with soluble salts, corrosion products, solvent entrapment and solvents from cargoes or processes; and Nonosmotic – which is associated with cathodic disbondment, cold wall effects and compressive stresses.

Paints and coatings are a combination of resins, solvents, additives and fillers that are formulated for a diverse range of conditions and applications and, as such, must be applied and cured correctly to suitably prepared substrates in order to ensure they perform to their maximum capability. Defects can manifest themselves at varying times in the lifespan of a paint or coating; the list below is not intended to be exhaustive and is indicative of the most common types of defects found.
