How to Waterproof Concrete Walls

One thing that a homeowner may want to know is how to waterproof concrete walls. Concrete is a good choice since it is less expensive and not to mention durable. However, there are also some disadvantages. Concrete can cracks due to moisture. The basement, kitchen, and bathroom are usually where any concrete walls might have damage. But waterproofing concrete walls can save you money and protect them from future damage. Below are the steps.

  1. Get into some work clothes. Wear gloves to protect your hands and goggles for your eyes.

  2. With a wire scrub, clean the walls by brushing off any loose dirt, dust, or debris. Remove any paint chips and other unwanted buildup with a knife to flatten the surface of the wall.

  3. Wash the concrete wall and let it dry. A clean wall ensures that the concrete sealer adheres better.

  4. Make a muriatic solution. Mix one part muriatic acid and 10 parts water.

  5. Clean the wall with the muriatic solution. The acid will take off other deposits like salt.

  6. Check the walls for cracks. For smaller cracks, widen them and moisten the area.

  7. Mix some cement and apply it to the cracks. Let it dry for a few hours.

  8. When the cement patch is dry, trace the cement patch with a piece of plastic to cover it. Use duct tape to hold the plastic in place.

  9. For five days, repeatedly take off the plastic, wet the concrete cement, and then cover it again. On the last day, the cement will be cured.

  10. Finally, apply the waterproof sealer. There are two types: compound and liquid. The difference is that the compound requires the wall to be damp, and the liquid is applied to a dry wall. Whatever you choose, follow the instructions that comes with it. Ensure you cover the entire wall, especially the repaired cracks. When it’s dry, you can opt to apply a second coating.

Fixing your house should be a top priority. To avoid any other possible nuisance in the future, one of the things you should know is how to waterproof concrete walls.
