How to Slap the Wall: Learn the Step by Step
For a well-finished wall, three steps must be done the right way, and learning how to splash the wall the right way is the first of them. You should know that for the wall to be ready to receive the final coating, it must go through the processes of: plastering, plastering and plastering. By carrying out these steps correctly, following the advice of specialists and consulting the NBR's on the subject, you will surely have the result you expect: a wall with an impeccable and longer lasting finish.
On the other hand, we were able to notice many buildings with poorly finished, deteriorated walls and with the final coating degrading more quickly. And most often, these problems originate from the poorly executed steps of cladding structures and brickwork. Whether done the wrong way or skipping steps, the consequences are serious, as the work loses quality, which requires constant maintenance and expenses.
Therefore, we have prepared a sequence of materials that will assist you in the process of carrying out the coating of masonry and structures. To begin with, let's talk here about roughcast, which is the first step to be carried out and which must be done very well to avoid the lack of adhesion of the subsequent coating, which can leave the wall fragile and looking unfinished. So come with us, because we will explain everything what you need to know about roughcast, care, application, step by step and also what the technical standards guide! Don't miss this opportunity and keep reading!
To understand how to do it the right way, you need to know, first of all, what roughcast is. So let's go. Roughcast is a more fluid mortar mix, used as the first layer on a wall to facilitate the adhesion of the plastering, which will then be covered by the plaster.
The main advantage that roughcast offers for cladding the structure is the fact that it provides support for plastering. This means that if the plastering if applied directly to a wall that has not been plastered, it is likely that plastering has no adhesion to the surface; therefore, roughcast provides the roughness necessary to adhere to the plastering, preventing the material from peeling off the brick or block.
There are two ways of plastering the wall: the traditional way, in which the bricklayer himself prepares the dough, following a very specific line with CP II or CP V cement, which is then applied to the surface; and the ready-made one, which consists of the use of the ready-made mixture sold in building material stores. When the dough is handled in the traditional way, it is important to certify that the bricklayer is aware of what he is doing, so that he can correct the consistency of the roughcast and have no future problems, understand?
Now that we've made it clear what roughcast is, let's understand what its classifications are. Generally speaking, we can divide the splashing into:
Now, let's get to what really matters: The step by step of how to splash the wall.
Now that you know how to plaster a wall the right way, it's important to know what the technical standards say about it to always work within the required standards, right? So, it is highly recommended that you make a habit of consulting them before carrying out any construction procedure! Let's summarize it here to make it very easy!
The standard states, regarding the constitution of the coatings, that wall and ceiling coverings can consist of roughcast and plastering, as a single-layer coating, or of roughcast, plastering and plastering. This article aimed to explain roughcast, but you can see it in our Blog the other topics.
Just to confirm what we said, NBR 13529/2013 defines roughcast as a “base preparation layer, applied continuously or discontinuously, with the purpose of standardizing the surface with regard to uptake and improve coating adhesion”. That's exactly what we said!
Regarding the application of roughcast, NBR 7200 states that roughcast mortar must be applied with a fluid consistency, by casting it on the wall and ensures the use of additives that improve adhesion. Finally, it determines that in regions where the climate is very dry and hot, roughcast must be protected from the direct action of the sun and wind through processes that keep the surface moisture at least 12 hours after application.
When plastering the wall, you need to pay attention to cautions that must be taken to avoid problems and accidents. Let's understand better:
