Waterproofing Exterior Walls: Steps to Follow

When exterior sides of your house are exposed to high humidity or rainwater, moisture and water can move via the masonry hence affecting its internal walls. In this case, the walls can remain damp for a relatively long period before drying. This can result in irreversible damage as well as mold growth. In humid areas, a damage that occurs as a result of water penetration is a common thing. You know what? The exterior waterproofing Minneapolis builders provide can help you prevent mold from attacking your building. 

Checking walls for faults 

You know what? Waterproofing external walls can only be effective if moisture or rainwater is the main cause of the problem. Before you begin looking for waterproofing products, it’s imperative to eliminate other factors that may lead to structural dampness. Find out if there are cracks in your bricks or condensation resulting from a burst water pipe. You can apply the right waterproofer for prevention purposes. 

Cleaning the gutters 

Clogged gutters can initiate several problems in a building. Other than making water flow towards the wrong directions, clogged gutters can also retain water. The water may be absorbed by the fascia boards leading to a plethora of issues including mold, rotten wood, and leaks. Cleaning your gutters twice a year will not only help you avoid these problems, but it will also help keep your house healthy. 

Get the most appropriate waterproofer 

Nowadays, there are different types of waterproofing products in the market. Getting the right type will help you protect your house from external moisture. Concrete waterproofing coating is one of the most effective waterproofing products in the market. It is a cement-like substance that sticks on concrete as well as masonry permanently. This product can be applied to any types of surface including painted walls. 

Waterproofing paint is another good example of a waterproofer. Its features are similar to those of acrylic wall paint. This product is almost perfect when it comes to waterproofing performance. In this case, it is necessary to get a breathable formulation, which is specially designed to make it easy for walls to eliminate moisture and also breathe. Silicate-based concrete is another good waterproofer. It reacts with the ingredients within the concrete and masonry resulting in a waterproofing coating. This product is most appropriate for unsealed and unpainted walls. 

Apply plaster waterproofing additive 

Guess what? Plastering can help enhance aesthetics, make a structure more solid, and also protect it from moisture ingress. Most exterior plasters have reliable waterproofing features. You can also prevent water infiltration problems and also avoid reoccurrence by including a waterproofing admixture into the plaster. 

Preparing the walls and applying a waterproofer 

Before you start the actual waterproofing process, ensure that your exterior walls are in good condition. It is important to repair any cracks and patch holes that may be present on the wall. Remove dust from the wall and then clean the surface using water. You can now start applying a waterproofer using either a brush or a roller. If you need a second coat, allow the initial coat to dry before you apply the next coat.
