Also known as 'flashing', poor sheen uniformity can be identified as shiny or dull spots on a painted surface that can lead to an uneven gloss.
Yellowing is the development of a yellow cast in aging solvent-based enamels. It's most noticeable in the dried films of white paints or clear varnishes.
Wrinkling in paintwork can be identified by a rough, crinkled paint surface, which occurs when uncured paint forms a 'skin'.
Sagging is the downward drooping movement of the paint film immediately after application that results in an uneven coating
If you've noticed black, grey or brown areas on your painted surface, chances are you're dealing with a mould problem.
Roller spattering is the tendency of a roller to throw off small droplets of paint during application.
Poor stain resistance is the failure of paint to resist the absorption of dirt and stains.
Poor scrub resistance can be identified if paint film wears away when scrubbed with a brush, sponge or cloth.
Poor hiding is exactly what it sounds like. It's the failure of your dried paintwork to obscure or 'hide' the surface to which it is applied.
Poor flow and levelling is when paint fails to dry to a smooth film, resulting in unsightly brush and roller marks after the paint dries.
Roller marks or stipple is the unintentional textured pattern that's left in the paint by the roller.
Picture framing occurs when a wall is painted with a roller, but is brushed at the edges and corners. The brushed areas generally appear darker, resembling the frame of a picture.
Have you noticed that there are areas of denser colour or higher gloss where wet and dry layers overlap during painting?
Foaming or cratering is the formation of bubbles (foaming) and resulting small, round concave depressions (cratering) in a paint film, during paint application and drying.
Cracking, flaking or peeling is the splitting of a dry paint film. This is a problem that needs fixing as it can 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.
