The Backing Coat

The skim (finish) coat is the final coat and is responsible for smoothness. It is not designed to flatten so the background to which it is being applied needs to be flat.

Firming up

An uneven background can result in some areas having a greater thickness of plaster. The firming up process is influenced by the thickness of plaster. Progression through all the stages of skimming is in turn influenced by the firming up process. Therefore if one part of the wall is twice as thick as another it could take twice as long for it to firm up and therefore move through the stages and could result im an uneven finish.
