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.Leng team 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.
Leng 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.
