When is plastering skimming?
Skimming specifically refers to the process of applying a thin layer of finishing plaster to create a smooth finish for the surface of walls or ceilings, usually so that it's ready for painting or covering with wallpaper.
In the stages of plastering a wall or ceiling, skimming is generally considered to be the final stage.
What is plastering vs skim coat?
A skim coat refers to the layer lime that is applied over rough cement, which may then be smoothed out using various plastering techniques.
One of the main differences between general plastering and a skim coat is the thickness of the coating. Skim coats are typically thinner (applied to a thickness of up to 5mm), while general plaster can applied to a thickness of anywhere from 5mm to 30mm.
