Development of a yellow cast in aging paint solvent-based enamels


A rough, crinkled paint surface, which occurs when uncured paint forms a 'skin'.


Downward drooping movement of the paint film immediately after application, resulting in an uneven coating.

Roller spattering

Tendency of a roller to throw off small droplets of paint during application.

Roller marks/stipple

Unintentional textured pattern left in the paint by the roller.

Poor stain resistance

Failure of the paint to resist absorption of dirt and stains.

Poor sheen uniformity

Shiny spots or dull spots (also known as 'flashing') on a painted surface; uneven gloss.

Poor scrub resistance

Wearing away or removal of the paint film when scrubbed with a brush, sponge, or cloth.

Poor hiding power/opacity

Failure of dried paint to obscure or 'hide' the surface to which it is applied.

Poor flow and levelling

Failure of paint to dry to a smooth film, resulting in unsightly brush and roller marks after the paint dries.

Picture framing

An effect of non-uniform colour, or sheen level that can appear when a wall is painted with a roller, but is brushed at the edges and corners.

Mud cracking

Deep, irregular cracks resembling dried mud in dry paint film.


Black, grey or brown spots on the painted surface.


Appearance of a denser colour or increased gloss where wet and dry layers overlap during paint application.


Formation of bubbles (foaming) and the resulting small, round concave depressions (cratering) when bubbles break in a paint film, during paint application and drying.


Splitting of a dry paint film through at least one coat as a result of aging, which ultimately will lead to complete failure of the paint ...


The gloss of paint can wear down when subjected to rubbing, scrubbing or having an object brush up against it.


Undesirable sticking together of two painted surfaces when pressed together (e.g. a door sticking to the jamb).
