Skim-coating

The phrase "skim-coating" means different things to different people, both customers and contractors. Overall it is applying some type of plaster to entire wall or ceiling surfaces to achieve cosmetic smoothness and/or to build-up a new layer of plaster to even out imperfections or to level surfaces that are irregular.

On the one hand it can mean simply applying 2 very thin layers of joint compound to walls or ceilings to even out the look or the textures of old roller marks, etc. This is purely cosmetic.

On the other end of the spectrum it can refer to the last stage of restoration work after old, crumbling brown coat (the structural grey base plaster that is under the white finish plaster) is replaced and holes and cracks are repaired. After repairs, surfaces are covered with about 1/8" or more of skimmed plaster to make the surfaces look even and new.

Fiberglass mesh is sometimes used under the skim-coat to help prevent future cracking. Joint compound or compound mixed with plaster is applied in successive coats over at least a few days to achieve the desired result. Only minor sanding is necessary if this is done well. A more costly option is to use Diamond coat - a wet-troweled finish plaster that mimicks the old-fashioned plaster and lime mixture. This is applied and finished while wet (no multiple layers required) and results in a harder, higher-quality surface.

To sum up "skim-coating" can mean many things and, as with everything, there are many levels of quality available. Costs vary greatly depending on the process used, number of coats needed, how level you want your surfaces to be (as opposed to just smooth), and whether minor or extensive repairs/restorations are required beforehand.
