Effective Reverse Waterproofing Instructions for Constructions

Water seepage and mold on walls are something that no homeowner wants to happen to their construction. However, with the hot and humid climate in Vietnam, wall seepage is an inevitable situation if waterproofing is not done carefully.

Currently, construction works use many integrated waterproofing measures to protect the structure from moisture penetration. In which, the solution of using reverse waterproofing paint has been and is being used because of its optimal waterproofing ability.

In the following article, Uskolor’s Waterproofing Expert will help you have general knowledge about the reverse waterproofing method and guide you on how to effectively prevent reverse waterproofing for constructions.

• 1. What is reverse waterproofing?

  Reverse waterproofing is the method of waterproofing on the inside of the structure, where it is not in direct contact with the source of the leak. This is a waterproofing method commonly used to prevent capillary phenomena occurring inside the structure.

  To put it simply: Water seeps from the outside of the wall, we create a waterproofing layer on the inside of the wall. Or water seeps from the inside of the tank, we create waterproofing on the outside of the tank, which is also reverse osmosis. Reverse osmosis is a method of waterproofing in the opposite direction to the source of the leak, combined with the forward osmosis method, providing an optimal protection solution for the structure.

  1. Why is reverse waterproofing necessary?

  – In cases where forward waterproofing is not possible, reverse waterproofing is the optimal method.

  – In case 2 houses share a wall but cannot waterproof from the other side, then you will have to use reverse waterproofing for your house’s wall

  – Constructions such as basements and water tanks should use the reverse waterproofing method because this is where moisture seepage often occurs.

  – When the space between 2 houses is built too close, the distance between the 2 wall gaps is too narrow to use forward waterproofing, then you must use the reverse waterproofing method inside the interior wall.

  3. Effective reverse waterproofing paint construction process

  3.1. Prepare the wall surface

  Your house’s wall surface needs to be clean and dry. In case the wall is moldy and damp, you need to scrape off this old moldy paint layer, you can use sandpaper. If the wall is too dry and cracks appear, you should moisten the wall with clean water. The ideal humidity for the wall is <16% when measured with a professional meter.

  3.2. Paint mixing steps

  Mix white cement and water together, stir well. Then mix the waterproof paint, stir well to blend the ingredients together and avoid clumping. The mixing ratio varies depending on the type of paint. The general formula will be:

  1.5 liters of water: 1 kg of white cement: 1 kg of waterproof paint

  When cement is mixed with water and waterproof paint, it will create a curing reaction that helps seal tiny holes and prevent maximum water penetration into the wall. Thus, your paint layer will be abrasion-resistant, highly elastic, alkali-resistant, salt-resistant as well as crack-resistant. In general, it is much more effective than just painting a few coats of regular paint. You should carefully research the type of paint you use and consult with builders to be more sure about the mixing ratio.

  3.3. Painting process

  To achieve maximum effectiveness and create perfect beauty for the wall, you should paint 2 coats of waterproof paint and 2 coats of topcoat. For walls with deep cracks, you can apply 3 layers of waterproof paint for high efficiency.
