“Your walls are the foundation of your house. The weather out there will not be nice and you need to pay special attention to your house’s exterior walls. It is not enough to paint the wall. After dealing with rain, snow, wind, dust, and the heat of the outside environment, the paint will start peeling off.”

Thus, waterproofing is the best way to ensure that your walls are protected and retain your house’s longevity. At the same time, it is vital to reduce your frequent renovation cost. So, here are some of the simple steps for providing effective waterproofing solutions to your home.

Interior waterproofing systems, installed by a professional contractor, can keep the moisture away throughout the home.

Step 1: Properly expose the outside part of the wall

To start with waterproofing your exterior walls, make sure it is properly exposed to work on. Your house walls possess a lot of dirt, which creates an additional layer over the wall. Get rid of all the filth and dust from the walls. And before doing so, remove all the drainage pipes and the old field tiles to get proper access to every corner and area of the wall.

Step 2: Thoroughly clean the walls

The outer part of the wall is usually covered with a lot of dust and dirt from the air. To ensure the efficiency of the entire process, you need to clear off the debris and dust thoroughly. The dirt and debris should be cleaned with a broom, brush, or scraper. Then wash it with a power washer.

Cracks and holes can develop on your exterior walls over time. Follow up the cleaning process with a thorough look at the cracks and holes in the wall. Simply fill them up with cement.

Most of homeowners get worried about cracks in the foundation. But the fact is, not all foundation cracks affect the home’s structural integrity. Sometimes cracks can be caused by shrinkage during the concrete curing process. These unsightly, non-structural shrinkages, commonly known as hairline cracks, don’t put your home in immediate danger. But on the other hand, structural cracks are serious business.

All over the internet and TV, you find websites and programs with step-by-step guides for DIY foundation repair. But the truth is that a foundation should not be experimented on in a DIY project. Foundation repair requires years of experience and specialized tools. When it comes to foundation repair, contact a foundation repair expert.

Step 6: Apply the water-proofer

Apply the water-proofer thoroughly on the walls with either a roller or brush. If you want to apply more than one coat, give a thin coat first. Add the second coating after the first one has dried.

Step 7: Apply tar and heavy-duty membrane

“If you want to add more strength to the layer, you need to use a tar-based pitch after you’ve dried the cement. It should be applied everywhere on your wall.”

After that, you need to apply a heavy-duty plastic or rubber membrane, which will ensure the proper care of your walls.
