Water discharge or additional unconditionally wet ingress in buildings results in damp, uncomfortable internal environments; deterioration of interior finishes (including mold growth); unpleasant moist areas on wall and ceiling surfaces and multiplied concentrations of harmful pollutants moving occupant’s health The absence of water from structures is thus not only fascinating but also a significant worry for the building’s occupants.
Seepage of water through the exterior walls Water flowing through external walls has been discovered to be a common problem among Mumbai residents due to a big downpour.
Watercourse through external walls at intervals over the first five years after a building’s completion. The issue is further complicated by Mumbai’s high humidity and abundant rainfall. The current of airspeeds close to high-rise buildings increases the likelihood of water seeping.
As a result, building envelopes should be adequately built and constructed to prevent water infiltration.
A variety of factors causes water seepage through external walls.
- Cracks and joints in the walls
- The materials’ absorption and permeation
- Walls have construction joints.
- Pervasive wetness
- Capillary action causes rising wetness.
- Construction procedures that are substandard
- Concrete or plaster honeycomb constructions.
- Gaps in separation
Water and moisture can move through the brickwork and impact your internal walls when outside walls are exposed waterproofing treatment in Hyderabad to rains or high humidity. This implies that your walls may remain damp for an extended period before drying, perhaps resulting in mold development and irreversible damage. In humid climates like Florida, wall damage from water penetration is WHEN not IF.
How can you prevent water and mold from affecting your walls? By following the following seven steps to waterproofing exterior walls.
How can you keep your walls dry and mold-free? Following the seven steps mentioned below will help you waterproof external walls.
Check for flaws in the walls: Waterproofing external walls are ideal only if the walls have become ceiling waterproofing solutions damp due to rain or moisture. It’s critical to rule out any other reasons for structural dampness before looking for waterproofing goods. Anything from cracks in your brickwork to humidity within the wall to a busted water pipe could be the cause.
After you’ve resolved the problem, you can move on to the next step.
- Clean your gutters: Clogged gutters cause several issues, including rotting wood, leaks, and mold. They also store rainwater, which is gradually absorbed by the roof’s wood or fascia boards, potentially leading to several issues such as rotten wood, leaks, and mold. By cleaning your gutters twice a year, you may avoid all of these problems and keep your home healthy.
- Choose the correct waterproofer: There are various waterproofing products on the market today to assist homeowners in protecting their homes from outside moisture. Here are a few products to think about
- Concrete waterproofing coating, a cement-like compound that binds permanently to concrete and masonry and can be applied to any surface, including painted walls;silicate-based concrete sealer, which forms a waterproofing layer by reacting with the components in masonry and concrete; this sealer can only be used on unsealed/unpainted walls; Waterproofing paint is identical to acrylic wall paint, with the exception that it performs better in terms of waterproofing. It’s critical to select a breathable formulation designed to allow walls to breathe and expel moisture. The product can be used on already painted surfaces.
3.Use a plaster waterproofing additive: Plastering can help improve aesthetics, solidify walls, and protect them from moisture infiltration. Although most external plasters have waterproofing properties, by simply adding a waterproofing additive to the application, you may solve water penetration problems and prevent reoccurrence.
4.Prepare your outside walls for waterproofing: Regardless of the product you choose for waterproofing exterior walls, you must first have your walls in good shape. To fix cracks and patch holes, you’ll need to utilize a high-quality filler. Allow enough time for the filler to dry completely before grinding. To guarantee a proper adhesion between the waterproofer and the substrate, sand away rough, uneven parts, rinse the surface with water to eliminate dust and let the walls dry thoroughly.
- Apply the waterproofer with a roller or a brush, depending on your preference. If a second coat is required, let the first coat dry completely before applying the second. Enough substance should be used to provide an impenetrable barrier to penetration.
- Test: It is critical to conduct a water-tightness test to assess the performance of the items used to waterproof exterior walls. Water should be sprayed on the wall surface for a couple of hours with the nozzle set at a 30-degree angle for this test. If a moisture meter indicates that there is no dampness in your home, it will pass the test. You’ll not only save money by waterproofing external walls, but you’ll also save time.
