What is external wall waterproofing?
External wall waterproofing is a protective measure taken during the repair/renovation of a house to prevent water from entering from the outside. The waterproofing process includes surface cleaning, crack filling, coating the surface with a protective barrier, and preventing water accumulation near walls. These measures protect your home from external wall cracks, water seepage, water leakage, and other water-related damages on your external walls for years to come.
Causes of water seepage on external walls
Harsh weather conditions, such as heavy rainfall or extreme temperature fluctuations, can damage the wall, leading to cracks and the inflow of water 
Poorly designed plumbing or clogged drainage systems may fail to effectively divert water away from the walls, causing seepage issues
As houses age, external paint can deteriorate, allowing moisture to penetrate the walls over time
If external paint was not applied correctly during construction or was of low quality, it may fail to protect against water intrusion.

Recognising external wall problems due to leakage/seepage
- Peeling paint or bubbling on exterior walls indicates wall seepage
- Visible flaking, chipping, or deterioration suggests water-related damage
- Stains or discoloration on exterior walls may be due to wall seepage
- Moss, algae, or dampness (seelan) on exterior walls are clear signs of moisture exposure
Damages due to external wall seepage
Seepage attracts termites and carpenter ants, causing house damage and health risks
Wall infiltration leads to electrical problems, risking short circuits and wiring corrosion, which are fire hazards
Seepage can ruin exterior finishes, causing paint peeling, discolouration, and stains
External wall seepage diminishes property appeal and value, making it less attractive to potential buyers
Coating v/s painting: Which is better?
- A coating is a thick product of 100 Microns that requires no water addition, giving it a thick viscosity. Unlike paint that only covers the aesthetics of your house and is 50-60 Microns thick, a coating has 100% more elongation properties to cover your external walls flexibly.
- Coatings establish a vapour barrier between the surface and its surroundings to safeguard your external walls from water-related damage that causes an array of issues and repairs. While ordinary exterior paints are prone to damage due to moisture and can start peeling and blistering over time, a coating increases the durability of your house’s external walls by providing additional protection from water infiltration.
- Both painting and coating are important for a house’s external walls. While paint elevates your home’s beauty and aids in protection, waterproofing ensures its longevity and stability. The Dr. Fixit Raincoat coating range is a versatile two-in-one solution, offering the advantages of both paint and waterproofing. Functioning as a genuine 'raincoat' for your home, it safeguards against water-related harm while enhancing its visual appeal.
