Plastering Wall - An Easy Job When You Know How
It is important to be equipped with the drywall tools, materials and the knowledge to do the job if you are going to plaster a wall. It is an easy job and you may be surprised at how fast it can be done. A three-coat plaster application is normally needed for wall rebuilding. Some kind of finesse is required for plaster application, as the process should be able to provide support for the surface, handle the weight load and prevent cracking. The final result should be a smooth surface ready for paint or wallpaper.
For a three-coat plastering job, first two rough coats should be applied and these coats are combination of aggregate, fiber, gypsum and water. This mixture is what will make up the wall base. Sand is the most commonly used aggregate for rough coating. Lime used comes from grounded oyster shells or limestones, while gypsum is usually used instead of lime as it dries faster. The initial coat is called scratch coat as after its application a comb-like tool is used to scratch the surface to make it rough. The second coat is known as the brown coat and applied directly into the scratch coated surface.
The last coat is called traditional lime finishing coat and it is a fine mixture to be prepared by the plasterer. First to be prepared is the lime putty and it will be circled on the mixing board. Water will be poured on the circle and the water will be sprinkled with plaster. Once the plaster and lime mixture is ready, it will be used as the final plaster coat. This is the combination that provides the shine and hardness to the final coat. There are plasterers who use spray bottles to keep wetness of the plaster as they work - for guaranteed smooth final touches. The process of wall plastering is basically based on the lime putty used and on the surface where it is to be applied.
The quality of the plastering job and adhesion degree depends heavily on this, not forgetting the use of the best drywall tools. That is why a brick surface should be treated first prior to plastering. You should know that for every plastering job, a wall is surely unique. There are basically two main plaster types; gypsum based and cement based. Outdoor plastering requires cement based, while gypsum based is used for the indoors. Basically, gypsum plaster is bonding, browning and metal lathing kind of plaster. The ready-made modern plaster is pre-mixed with vermiculite, perlite and a few other additives. These components allow the wall to be fire-resistant and highly insulated.
Before using the plaster, you should only use clean good water. When a plastered wall has different absorption, you can solve this issue by using a bonding sealer that will key the surfaces. This will ensure that a clean and smooth finish will be achieved. And any single time you will need to do a better job, make sure you first start by using the right Drywall Tools because this is what matters most.
