Sometimes even if the plastering is done correctly, it gets cracks. In such cases the joint compound may hold too much water and then crack when it dries up.
As with painting, plastering needs a base coat. This base/undercoat may need building up in 2 layers depending on the condition of the walls and the thickness of plaster needed to improve them.
Plastering jobs involve mixing and applying different kinds of plaster in order to provide a finish to internal surfaces.
Skimming is the process by which a thin layer of plaster is applied to a wall or ceiling to provide a smooth surface.
Plastering equipment will usually need replacing if plaster is not cleaned off with water before it dries and this can get expensive and is wasteful.
As soon as you have mixed the plaster you should empty it out of the bucket onto a wet board which should be lifted off the ground high enough to enable you to get your plaster onto your hand board (hawk) easily.
Any flecks of dried plaster in your buckets or on your equipment from previous sessions will later break off to contaminate future batches of plaster.
This is the most important coat and this coat of plaster is called a skim. Skimming requires practice, so go about it slowly and follow instructions carefully.
Mixing is a very important phase in a plastering job. With the help of a mixer drill the mixing plaster can be made easily, especially if the quantity is large.
Don't - forget to wash all your tools and buckets once you are finished otherwise you will make it harder for yourself the next time.
