To ensure the durability and quality of the concrete structure, it is important to protect the building from any exposure to water. O exposed concrete treatment it is one of the most suitable solutions for these cases. It is a technique that maintains the integrity of the concrete and increases the useful life of the project. This method is widely used to carry out maintenance both in Facade of buildings as for other types of buildings, such as viaducts.
The apparent concrete provides a different air to the environment, since the material is exposed, that is, without coatings or finishes. The main objective of this technique is to ensure more durability for the project, preventing against infiltrations in facades, dirt accumulation and frequent maintenance.
In addition, when exposed concrete treatment is well performed, the material tends to last longer than originally designed. In this post, you will learn about the main benefits of this technique for construction. Check it out and enjoy reading!
Exposed concrete has been gaining the taste of Brazilian architects since the 1960s. One of the main forerunners of this technique was Oscar Niemeyer, who abused style in his projects, building true works of art revered around the world. The method, which consists of completely exposing the concrete, without any type of finish, can be applied to indoor and outdoor areas.
The main focus of treatment of concrete apparent is to preserve the original characteristics of the material to the maximum and extend the life planned in the architectural project. In addition, the treatment provides a beautiful and pleasant aesthetic look. Here are the main benefits of treating exposed concrete in the long term:
versatility — can be applied both to facades and to the interior of buildings. It can also range from rustic decoration to contemporary style, ensuring a unique appearance in each application;
protection — preserves the building against inclement weather, such as rain, sunlight and other climatic factors;
longer lifespan — when treatment is done properly, concrete tends to last for years without corrective maintenance;
Economy — how does it not need plastering, or concrete apparently it is an economical option, in addition, it requires little maintenance;
easy cleaning — only the use of pressurized water jets, dispensing soap or other products, is recommended;
valuation of the property — due to its durability and economy, concrete It apparently values construction and directly influences market value. The beauty that this technique offers also attracts attention, as it increases the price of the property.
The hydrofugation of apparent concrete
Os water repellents protect the substrates to protect against water and particles that may adhere to surfaces. Very suitable for outdoor areas, these products prevent infiltration and preserve places exposed to weather factors. They can be applied to different types of surfaces and are used to conserve and increase the lifespan of structures.
This material does not form a film once applied, completing the porosity in the region to avoid the appearance of stains and darkening of the grouts, resulting from water infiltration. O water-repellent silicone serves to protect the surface from the action of moisture and water, blocking infiltrations to prevent aesthetic damage to the material, in addition to ensuring more durability and lower maintenance. In addition, this product protects the substrate without modifying its original characteristics.
There are several specifications of waterproofing agents silicone-based products on the market, which must be chosen according to the place where it will be applied, the type of structure and the way in which they will be exposed to the elements. This product is sustainable, resistant and prevents dirt from accumulating, making it easy to clean.

Water-repellent silicone and acrylic varnish
The main difference between water-repellent silicone and acrylic varnish It is basically that the latter forms a layer on the surface after being applied, resulting in finishes that differ from the natural of the material. The resins or varnishes are also resistant and offer a beautiful appearance after application, leaving the surface matte, satin or shiny. For those who want to change this aspect, this would be the biggest advantage of acrylic-based varnish.
Another very significant difference is the issue of maintenance. While structures with water repellent last years without maintenance, places with acrylic varnish tend to deteriorate faster, due to the formation of the film. Exposure to the sun yellows the surface, causes cracking and peeling of the film. Therefore, to avoid further inconvenience, it is essential that maintenance be carried out as soon as the place shows the first signs of wear and tear.
O BlokSeal CC is a water-repellent silicone that offers maximum protection for facades and roofs. By preventing water infiltration, this product prevents internal finishes of the work from being damaged. It protects and preserves the structure without altering the brightness or color of the surface. In addition, this silicone prevents stains, efflorescence and darkening of the structure. Cracks and seeps are also common when the structure is preserved improperly.
The efflorescence
A efflorescence are whitish spots that appear on surfaces due to chemical reactions. The presence of free lime is found in substrates that contain cement in the composition, such as plastering mortars, and the exposed concrete itself.
When this material comes into contact with rainwater or other circumstances, it dissolves, causing stains on the walls. Surface hydrofugation is essential to prevent this type of problem.
The sealing of vertical joints
The appearance of cracks is among the various problems that can occur in a construction. The Sun is one of the main responsible for these pathologies, since the incidence of heat favors the dimensional movement of the structure, resulting in cracks and Trincas.
The sealing of joints in buildings serves to absorb movements and seal the passage of water. Thus, it is possible to protect the structure, ensuring the integrity, comfort and healthiness of the environments.
Normally, the infiltrations they occur due to weather actions, such as rain, solar radiation, winds and other climatic factors, favoring the passage of moisture and water. The structure may have leaks, leaks, stains and peeling, which impair the aesthetics of the environment. In addition, infiltration can compromise the entire building and cause serious damage.
As we have seen, concrete treatment apparent is important to increase the durability of materials, ensure safety, integrity and stability of the structure, in addition to making the environment more beautiful and with less maintenance. Use quality products and count on qualified professionals to provide more comfort and savings to your architectural project.
