detachment of a uniform layer of a coating or surface material, usually related to internal movement, lack of adhesion, or passage of moisture. View Glossary Photo Example
Occurs when a coating loses its cohesion.
(scaling) the detachment of small pieces of the coatings
A form of paint failure characterized by the detachment of small pieces of the film from the surface of previous coat of paint. Cracking or blistering usually precedes it.
a Coating film failure in which pieces of the film separate from the substrate. .
Detachment of small area/chips of a coating film from the surface to which it was applied due to loss of adhesion.
Disintegration into small pieces or "flakes." Ref. "Scaling."
Small pieces of paint surface coming off. Cracking or blistering usually occurs before flaking.
A term commonly used regarding gravestones to indicate minor delamination of surfaces or otherwise unsound stone which easily peels off in small sheets or layers.
Flaking is the lifting of small-to-large sections of the paint and is due to poor adhesion and to the brittleness of the paint. The causes can be varied, for example the defect could be caused by efflorescence or the migration of soluble salts to the paint-media interface which can cause the paint to be forced off the surface. The paint may react with moisture and any traces of alkali to decompose the paint - this is called saponification. It may be due to failure to remove millscale from the steel before painting.
Paint failure where small paint pieces detach from surface of previous coat of paint. Usually preceded by cracking or blistering.
A condition in coated sheet where portions of the coating become loosened due to inadequate adhesion.
The detachment of pieces of paint from the substrate, caused by a loss of adhesion and elasticity. Also known as scaling.
A condition sometimes occurring during removal of masking tape in which flakes or particles of paint break off the tape backing.
Peeling, exfoliation, delamination or spalling in which detachment of small pieces from a larger stone occurs.
A condition occurring when small pieces of a paint film break off.
Extreme cracking causing paint and/or ground layer to dislodge from the support, often through a combination of cleavage and cracking. Flaking Examples
A form of paint failure characterized by the detachment of small pieces of the film from the surface of previous coat of paint. It is usually preceded by cracking or blistering.
The peeling off of a glaze or slip from a clay surface.
Lifting of the ink from the underlying surface in the form of flakes or scales (poor adhesion).
