They are usually applied on brick wall; block wall or any other concrete wall surfaces.

On the other hand, plastering is referred to a layer of decorative moulding on wall or ceiling; it is also commonly known as rendering in construction industry. However, there are some slighty difference generally by plastering contractor in Auckland. Plastering is a term that being used for interior wall, ceiling while rendering is referred to external building application. Anyway, these two terms are interchangeable in construction industry; they are applied to decorate the wall, ceiling so that another protective coating layer can be created on top of the substrate. Furthermore, plastering contractor needs customer to aware that, plasterwork is not to create flat neither smooth surface, rather it is being applied for relief decoration.
Skimming creates smooth surface finishes, it involves a specialized process by skim coat contractor. First, skim coat specialist needs to apply a muddy plaster compound layer onto damaged or uneven wall and ceiling surface, for the sake of repairing the rough surface and subsequently turn it into a smoother finish.
Wall that has gone through long aging process will experience portion that is damaged by water leaking, scratches, other potential external forces and internal wall quality issue. Skimmer will need to make sure the holes, deep scratches are being filled up before applying two layers of skim coat compounds. Then and there, surfaces will be treated with sanding before any wallpaper or paint applied on it, right after the coat dries and has become smooth.
Plastering supplier usually supply plaster material that comprises of lime, gypsum, cement or some other components. Although manufactured finished goods will be presented in the form of dry powder, water is key to the mixture before it forms a stiffer paste that has high workability, but application must be done as soon as possible in order to prevent it from hardening. The reason why plastering contractor will mix the compound with water is because of crystallization process that releases the heat which then makes hardening of hydrated plaster.
Skim coat applicator is also normally the painting contractor, because in order to have painting work to be done, it must be coupled with quality skim works. The water-to-powder ratio adjustment of skim coating should be carried out carefully, to prevent the situation where compound becomes too watery and it cannot stick to trowel tool; on the other hand, insufficient water will cause the compound look like cake and solid form.
Plasterwork is also suitable to be applied on those places where decoration is required to hide structural support framework, for instance, steel, timber or plastic. Plastering applicator usually capable to apply multiple types of plasters such as lime plaster (lime and water), cement plaster (made by sand, cement and water) which is most common, and the other one that is also common is known as gypsum plaster (calcium sulphate and water).
