External wall waterproofing solution for repair and renovation
What is external wall waterproofing?
A: External wall waterproofing is a protective measure used during the repair or renovation of a building to prevent water from seeping into the structure from the outside. The process involves several steps, including:
- Surface Cleaning: Removing dirt, dust, and loose particles from the wall surface to prepare it for treatment.
- Crack Filling: Sealing any cracks or gaps in the external walls to block water entry points.
- Protective Coating: Applying a waterproof barrier to shield the surface from water ingress.
- Water Management: Preventing water accumulation near the walls by ensuring proper drainage systems.
These measures effectively protect your home from external wall cracks, water seepage, leakage, and other water-related damages, ensuring durability and long-lasting protection for years.
How to recognize external wall problems caused by leakage or seepage?
External wall issues caused by leakage or seepage can be identified through the following signs:
- Peeling or Bubbling Paint: Indicates water seepage beneath the surface of the walls.
- Flaking or Chipping: Suggests water-related damage, leading to the deterioration of wall surfaces.
- Stains or Discoloration: Often caused by persistent moisture or water seepage through the walls.
- Moss, Algae, or Dampness (Seelan): Clear indicators of prolonged moisture exposure, which can weaken the wall structure over time.
These signs highlight the need for timely external wall waterproofing to prevent further damage.
Coating vs. Painting: Which is better?
A coating is a thicker product, approximately 100 microns, that does not require water addition, resulting in a dense viscosity. In contrast, paint is primarily used for aesthetic purposes and is about 50-60 microns thick. Coatings also offer 100% more elongation properties, allowing them to flexibly cover and protect external walls more effectively.
Coatings provide a vapor barrier between the surface and its surroundings, safeguarding external walls from water-related damage, which can lead to costly repairs. Unlike ordinary exterior paints that are susceptible to moisture damage, peeling, and blistering over time, a coating significantly enhances the durability of external walls by offering superior protection against water infiltration.
Both painting and coating are vital for maintaining your home’s external walls. While paint enhances the visual appeal of your home and offers basic protection, waterproof coatings ensure longevity and structural stability.

FAQ's
Waterproofing is a crucial step in protecting your home from leaks, dampness, and structural damage. Whether you’re building a new house or upgrading an existing one, applying the right waterproofing solution can prevent costly repairs in the future. It serves as a protective barrier against water infiltration, ensuring the longevity of your walls, roofs, and foundations.
Here are some of the most commonly used waterproofing techniques:
1. Cementitious Waterproofing
This is one of the simplest and most widely used waterproofing methods. It involves applying a cement-based coating that forms a protective layer over surfaces, making them resistant to moisture. It is commonly used in bathrooms, basements, and water tanks due to its easy application and durability.
2. Liquid Waterproofing Membrane
This method involves applying a liquid coating using a brush, roller, or spray. Once dried, it forms a seamless, flexible, and highly durable waterproof layer, making it ideal for protecting walls and terraces. The effectiveness of this technique depends on the quality of the polymer used in the liquid membrane.
3. Bituminous Membrane Waterproofing
A commonly used solution for roof waterproofing, this method involves applying a waterproof membrane made from bitumen (asphalt). It creates a strong barrier against water penetration. However, regular maintenance is required to ensure long-term effectiveness.
4. Polyurethane Waterproofing
This technique is ideal for flat roofs, terraces, and surfaces exposed to changing weather conditions. It offers excellent flexibility and waterproofing properties. However, before application, a thorough moisture assessment is essential to prevent peeling or membrane failure.
Choosing the right waterproofing method depends on the specific needs of your home. Proper waterproofing not only extends the life of your structure but also enhances its resilience against water damage.
Waterproofing protects your home from leaks, seepage, and damp walls caused by heavy rainfall. It prevents water from collecting on your roof or terrace and seeping into the structure.
- During construction:Waterproofing should be an integral part of the construction process to ensure long-term durability and protection of your home.
- During Renovation or Repainting:If you’re renovating or repainting your home, it’s the correct time to check for leaks and seepage. Addressing these issues with waterproofing ensures your newly renovated home remains beautiful and damage-free.
- Before Monsoon Season:Waterproofing before the rainy season helps prevent water damage, leaks, and dampness caused by heavy rainfall.
- At the First Sign of Damage:If you notice damp patches, cracks, or seepage, don’t delay. Immediate waterproofing can prevent further damage and costly repairs.
