Semi-transparent stains or glazes, which are applied over hard, dry paint coating
of a different Color called ground coat. While the scumble is wet it is
manipulated to partially expose the color of the ground coat in various grain
patterns and broken color effects, including imitation of various marbles.
A skilled applicator can create patterns like marble, wood grains etc. on steel
and plastered surfaces. Commonly, some steel furniture manufacturers use
these techniques to give steel furniture a wood grain finish.
Priming paint applied to timber or metal building components while still in the
workshop and before delivery on site. When left exposed to weather for long
periods such primers may be rendered ineffective. Poor storage before fixing
may result in mould infection, moisture penetration in wood and on primed steel
rust together with mechanical damage.
Before final painting shop priming should be closely examined. Any mechanical
damage should be repaired. If there is any growth of rust by pitting and flaking
the base has to be prepared to bright metal and reprimed with suitable primer.
