Rain is one of the main enemies of the roofs and roofs of all buildings. The accumulation of water can cause leaks and damage to structures, finishes, and interiors; it can also represent a risk to health since they are a source for the reproduction of bacteria, fungi, and insects that can carry diseases. Therefore, the application of waterproofing on all roofs and roofs before there are leaks. The importance of the correct application of waterproofing comes in here.
Protecting the roofs and roofs of buildings from moisture damage should be a priority, especially when the rainy seasons approach. Nobody likes living in a leaky home or having to invest in repairing walls and items because of the build-up of moisture that seeps in from screaming. Using a waterproofer is enough to prevent excessive moisture from wreaking havoc. There are several types, each with special characteristics to adapt to different roofs or roofs, but they all have the same function: creating a protective layer against moisture.
Roof pitch, constricting material, and human traffic are the three factors that influence the type of waterproofing to use. In addition, if there are already identified leaks, leaks or grooves, and cracks in the surface. Other actions must be taken and the surface repaired before investing in any of the types of waterproofing.
Correct Application of Waterproofing
In general, the types of waterproofing vary according to the type of construction. To determine which coating will be the most suitable, the slope or inclination of the surface must first be assessed. Most people think that a completely flat roof or roof is a symbol of good construction. Still, the reality is that there must be a certain inclination. So that rainwater does not accumulate and can flow down into the gutters or drainage systems that have been installed.
If the roof is a smooth surface or an unevenness of less than two percent and pedestrian traffic, that is, people walking through the place, is sporadic, you can opt for acrylic waterproofing. These have a quick application and drying, plus they do not require specialized labor, and on average, they offer up to five years of protection.
Another type of waterproofing is asphalt, which adjusts to various climates and structures. This type of waterproofing is recommended for roofs where there are many antennas or other types of obstacles that would limit the application of acrylic and have a longer life. However, it must be installed by specialized personnel who use the tools and material. Necessary for your application and the importance of the correct application of waterproofing.

On the other hand, on roofs and roofs where there will be constant pedestrian traffic, such as a terrace, balconies, or the roofs of residential buildings that tend to have other uses, such as washing areas or to keep pets. The best option is the use of polyurethane waterproofing, which has a high resistance to high structural movements, chemical resistance, UV rays, pedestrian and/or vehicular traffic. Depending on the system used for their placement, they have durations ranging from five to 20 years.
In the case of constructions that will have constant contact with water. Either due to the region or special situations, cementitious waterproofing agents are used. Which are used for concrete, mortar, and masonry constructions in areas such as cisterns, retaining walls, basements, among others. They are elastic, have a high level of weather resistance, and prevent the appearance of saltpeter, increasing the impermeability of concrete in foundations.
How is the correct application of the waterproofing?
After choosing the correct waterproofing method, the next step is the application. Most of the products can be applied by anyone following the instructions since their application is similar to paint. Still, others require more specialized knowledge, so it is required to go to a service specialist.
If you apply it, you can follow the following tips: first. You should check if the surface is waterproofed new or already has waterproofing. For new surfaces, there is no problem with the application. Little preparation of the site is required. But for surfaces that require re-waterproofing or maintenance, care must be taken that the new waterproofing is compatible with the existing one; You can also completely scrape the previous layer until you reach the slab and apply the new waterproofing. The latter is the most recommended to guarantee the useful life of the material and the importance of the correct application of waterproofing.

waterproofing
The application must ensure that the surfaces are spotless. In addition, it should be verified that there are no cracks that must be repaired, uneven areas that cause puddles, loose or poorly adhered parts of cement, and no grease or dust.
It is also important to purchase the highest quality waterproofing produced by manufacturers with the backing and reputation for ensuring their durability. If you are not sure of the quality, go to a specialist for advice and carry out the application appropriately. Experts usually work with reliable materials that will not require renovation until after the waterproofing is guaranteed and requires little maintenance.
Different types of waterproofing
The types of waterproofing are defined by the material with which they are manufactured. And where they can be applied, and other characteristics. One type is cementitious, which are used regularly in humid indoor areas, such as toilets. It is a semi-flexible or rigid material, depending on the variable. They are recommended for indoor use, where they are not exposed to sunlight. To avoid the process of continuous contraction and expansion.
A second type is a liquid membrane, a thin layer consisting of a primer layer and two top layers. It is more flexible than cementitious types, and its elongation property can reach up to 280 percent. The disadvantage is that the durability of the waterproofing layer depends directly on the type of polymer used by the manufacturer to make it. A low-quality polymer will result in low durability.
You can also find those with a liquid polyurethane membrane. This type of waterproofing is recommended for areas of the roof that are flat and exposed directly to the elements. It is a somewhat expensive material but offers greater flexibility. However, polyurethane is very sensitive to moisture content on surfaces. Therefore, before applying them, an adequate evaluation of the moisture content must be carried out on the surface, especially if it is made of concrete. Otherwise, flaking or flaking will be observed—the disunity of materials after some time.
Types of waterproofing
Another type of waterproofing is waterproof acryl, which is applied on concrete, asbestos, or galvanized sheets, a recommended material on roofs, roofs, horizontal and inclined exterior places. It is effortless to apply since it does not crack or crack. And they do not need another type of product to carry out the application.
One more type of common waterproofing on the market is asphalt. Which is a product that adapts to any surface that is exposed to the elements. There are several types, such as ecological and UV resistance. They can be applied alone or reinforced with polyester membranes for better waterproofing and insulation from moisture.
Acrylics are liquid waterproofing products made from resins, pigments, and ceramic components applied on concrete, asbestos, or galvanized sheet surfaces without prior preparation.
Other common waterproofers are prefabricated, which are recommended in foundations as a waterproof coating in cold application systems; The ecological ones, are made based on the recycling of tires. And do not contain lead or toxic solvents, are resistant to sudden changes in temperature, rain, and coastal areas. Based on acrylic copolymers, the elastics are applied cold on roofs or exterior walls, regardless of the type of material.
What to consider when waterproofing ceilings, walls, and terraces?
Roof and flat roof waterproofing vary according to the type of roof you are going to work on. Different materials can be used, such as asphalt or acrylic membranes on flat surfaces. But if it is used under the tiles, other types of waterproofing can be used, such as polyethylene and asphalt membranes. Waterproofing will depend on the correct application of the product rather than on the quality of the waterproofing material.
In the case of walls, where the main cause of deterioration is leaked. The durability of the concrete with which they are made is directly related to the wall’s porosity, permeability, and density. So it is essential to protect it using the right waterproofing. Moreover, there are different waterproofing materials for conserving the walls, which act on concrete, wood, or steel, which are made from cement, synthetic resins, asphalt, petroleum derivatives, acrylics, polyurethane, and other materials and importance of the correct application of waterproofing.
Finally, for terraces, among the most common materials to waterproof them can be found rubber chlorine, a liquid waterproofing obtained from rubber derivatives mixed with glass fibers. This material increases impermeability; it can adhere well to any type of surface, even alkaline ones, such as concrete, steel, cement tanks, and swimming pools, among others.
