To reduce the volume of waste in buildings and provide low environmental impact, roughcast adhesive is the best alternative.
This product is economical and very versatile, and can be incorporated into different projects and phases of the work. In addition, it offers excellent adhesion of mortars to the most different substrates of civil construction.
The roughcast adhesive is made from synthetic resins, is compatible with cement, gypsum and lime and is not affected by exposure to water after being added to the mortar.
The product has high resistance, offering more durability for the structure and finish. It can be applied indoors and outdoors and in places exposed to wetness.
Do you want to know more about roughcast adhesive? In this post, we will explain the advantages of this material and how quality products interfere with the result of your work. Check it out!
Roughcast and plaster
For a wall to be ready to receive the final coating, it must go through three fundamental steps: roughcast, plastering and plastering. These are essential phases of the construction process and must be complied with in accordance with the regulations to ensure the efficiency of the work.
With the help of trained professionals and quality products, after these three steps, the result will be a stronger and more durable structure.
When these steps are performed incorrectly or with inadequate materials, the tendency is for coatings to lose quality and deteriorate more quickly, requiring constant maintenance and causing aesthetic and financial losses.
Roughcast is the first step in the masonry process of a structure and must be applied to create a rough surface and provide greater adhesion to the second step, plastering. Considered the intermediate finishing phase, plastering performs the function of leveling the roughcast.
Finally, the Plastering is the third and final stage of the finishing phase and aims to make the wall uniform and smooth to receive the final coating. This work requires technical knowledge and, therefore, it must be carried out by a trained professional. In addition, quality products directly interfere with the final result of the work.
About Roughcast
Roughcast is a rustic coating applied to smooth masonry surfaces or structures of concrete. This layer serves to increase adhesion and is a mixture consisting of cement, lime and gypsum.
The application is carried out in a previously moistened place and on a single layer of mortar, which must be uniform, with a thin thickness and a rough finish. The roughcast provides support for the plunger.
Walls where plaster is applied directly to surface, without the application of roughcast, tend to deteriorate more quickly, since they will not have enough grip to sustain themselves.
Both on surfaces without roughcasts and on surfaces with poorly executed roughcasts, it is common to displace the plastering and plastering.
There are three types of roughcast: conventional, adhesive, and rolled. The choice will be made according to the needs and specificities of the work.
Every structure, regardless of its characteristics and materials, must be properly prepared before being plastered. And to ensure the adhesion of the material, it is necessary to apply the roughcast adhesive.
Roughcast adhesive: application and advantages
Roughcast adhesive is the best option for those seeking economy and high work performance. This synthetic polymer is highly concentrated and when added to the properties of cement, plaster and lime, it increases the adhesion of the mortar to the different substrates present in civil construction. The material can be applied to various places inside and outside the building. It is generally used to:
- Repairs between masonry and concrete;
- repairs to plastering, plastering and some critical points;
- traditional and rolled splashing;
- frame and molding fastener when added to plaster.
There are many advantages that roughcast adhesive provides for buildings. In addition to offering More resistance and plasticity, also durability to buildings, the product is highly concentrated, has high performance and reduces the volume of debris produced on the construction site. The roughcast adhesive also:
- reduces expenses, generating more savings;
- has high adhesion and strength;
- reduces the chances of the appearance of cracks and fissures;
- It provides less retrenchment of mortars;
- provides greater workability and flexibility to mortars;
- improves productivity in construction;
- has an excellent yield;
- increases waterproofness.
The roughcast adhesive is able to facilitate construction service and helps to obtain better results, providing more customer satisfaction. O BlokFix It is the adhesive for mortar, roughcast, plaster and concrete of Blok high performance that offers excellent adhesion to the most diverse substrates.
Tips for splashing on a wall
The surface can be plastered in the traditional way, in which the bricklayer is responsible for preparing the dough and applying it to the place. In these cases, it is very important to have a qualified professional to ensure that the material is handled correctly.
In addition, the substrate that will receive the roughcast application must comply with the requirements of the Brazilian Technical Standards Association (ABNT), in accordance with the guidelines of NBR 7200, which determines procedures for carrying out wall and ceiling cladding.
After preparing the mortar, applying it is an easy and quick process. It must be done with the aid of a mason spoon and a masseuse, in diagonal movements, from top to bottom.
Pay close attention to the amount of mortar to be placed on the wall and how to spread the material across the surface. It is important to apply so as not to leave uncovered areas and maintaining the recommended thickness of 3 mm to 5 mm.
The other form of Slap around a surface is using a mixture that is already prepared and is sold in houses made of building material. As they are ready and require no manipulation, these solutions can be more reliable and efficient.
Regardless of how chapiso is executed, a very important tip is, always moisten the surface before splashing. This will ensure that the water necessary for the roughcast to cure is not absorbed by the wall surface and the Cement curing don't be harmed for that reason.
