The external walls of your home are to be always protected. Be it the heavy downpour during heavy rainfall, the freezing winters, or the scorching summers. Especially during monsoons, it is imperative to protect and prepare the external walls as these are the most susceptible to getting damaged. Moreover, the external walls are exposed the most to rainwater. With every rainfall, the exposure only increases. The high humidity, water, and moisture are all the reasons for your exterior wall getting impaired.

The exterior walls are exposed to humidity, moisture, and extreme temperatures, which change over time and damage the surfaces. This promotes the growth of algae on the surface of the walls.

The exterior wall paint of your home may stay damp for a long time before drying on their own. However, this damping will lead to irreversible, irreparable damage and mold growth. Also, in a few places, with high rainfall and humidity, high water penetration and retention can become a cause of concern. You can easily manage waterproofing outside walls by following a few steps such as those mentioned below

  • Checking Walls for any Faults/Cracks

    One of the best methods of waterproofing for exterior walls is to look for any faults in the wall. These cracks in the bricks within the wall can burst a pipeline as well. Once you’ve fixed these cracks, look for the best waterproofing solution.

  • Clean the Gutters

    The issue with blocked/ clogged gutters is that they may not only lead to overflowing. The rainwater can be retained and absorbed, leading to more severe health problems. You can easily avoid this by cleaning gutters twice a year.

Choosing the Right Waterproof Method

There are various waterproofing exterior walls products available in the market to project the external walls of your home from getting damaged. A few products that you can use are:

  • Silicate Based Sealer

    This reacts in concrete and masonry to build a waterproofing coating. This can be used for both unpainted and unsealed walls.

  • Waterproof Paint

    This is like acrylic paints, with a significant difference in giving better performance. Moreover, you should look for a breathable formulation designed for walls to breathe and get rid of moisture.

  • Use Plaster Additives

    Plastering helps in improving aesthetics and makes walls more solid. At the same time, they protect them against any moisture by eliminating infiltration problems.

There are various methods of waterproofing that can be used from the different solutions available in the marker. Each of these products has other usages. Without the correct type of waterproofing materials, there can be grave damage and reduced comfort, thereby reducing the durability of the structure as well.

For this reason, it is a necessity that you apply suitable insulation material to the exterior walls that are highly exposed to water contact. These various methods of waterproofing your exterior walls are

  • Cement Based Waterproofing

    This method is the most straightforward and most convenient. These are best used in walls that frequently have high contact with water. Also, cement-based waterproofing is excellent for humid places and has full resilience. Any leakage can be taken care of using this method by providing insulation.

  • Liquid Waterproofing Membrane

    This is another preferred waterproofing method that provides a thin coating containing a primer coat followed by two coats applied by roller, trowel, or spray. It offers much more flexibility and is used in intensity nowadays. However, the durability depends on the polymer type that is used in making this membrane.

  • Liquid Bituminous Membrane Waterproofing

    This type of coating is used as a flexible protective coating for waterproofing in accordance with its degree of polymerization. It is also called the asphalt pavement method. It is made using bitumen rubber material and is used for both vertical and horizontal surfaces.

  • Membrane Waterproofing

    Membrane waterproofing is one of the most preferred and popular waterproofing covers that is applied using a torch flame source. Therefore, it adheres to the surface quite well. It is used in coating wet areas such as sloping roofs, flower beds, balconies, terraces, basement walls, water tanks, etc. It can even be used in areas such as patios and gardens encountering soil. It provides the same insulation quality in the exterior walls for more extended periods.

The exterior walls need to be waterproofed, as without this, the invading moisture can dampen the walls and spread to other areas. This becomes an excellent breeding ground for mold and mildew. This ends up damaging the walls and leads to various health issues. The use of general acrylic exterior paint or cement does not fulfil the waterproofing. As it does not create an envelope around the building.

The coating must be such that it combines the properties of aesthetics and effective waterproofing solutions. Also, water leaking is a common problem and can bother you unnecessarily and become a nightmare. You wouldn’t want to deal with leakages every other day. Additionally, prevention is better than cure, so why not get the exterior walls waterproofed to increase their life, thus bringing life into the structure?

The primary purpose of exterior wall paint is to make sure

● The paint looks pleasing

● More importantly, it should be such that it keeps the structure protected and provides a visual appeal

● The most important thing is to protect it from damping.

Conclusion

However, after choosing the right waterproofing method for your exterior wall, it is essential that you conduct a water-tightening test. It is crucial to evaluate and check the effectiveness of waterproofing products. Moreover, waterproofing works best when done at the time of construction. Using a high-quality waterproofing method in the initial stage using sand and cement is highly effective.

You can even use a waterproofing coating before painting the exterior walls. This will help in preventing water leakage.

Waterproofing forms a thick elastic film that blocks water and offers excellent waterproofing to the walls.
