Bittiness
Small specks and blotches on what should be a good painted surface. Usually caused by dust, broken paint skins or dirty equipment.
Blast tracking
The abrasion of the surface by the high velocity impact of particles such as grit that creates a surface profile for the coating to adhere to. The process may be wet or be complemented by the use of a vacuum to recover the spent grit.
Bleeding
Discolouration caused by the underlying colour seeping through the newly painted surface. Could be due to previous coatings such as dyes and creosote or perhaps nicotine stains
Blistering
Results from poor adhesion of the paint to the surface. Normal causes are damp in timber or moisture in the atmosphere.
Blocking
Unwanted adhesion between painted articles that are left in contact
Bloom
The formation of a deposit on the paint film which dulls colours and reduces the gloss
Brush hammering
A mechanical means of creating a traditional hammered finish to metal
Brush Marks
In heavy bodied paints it is difficult to avoid brush marks. Otherwise they are usually the result of poor application.
