Understanding the Need for Waterproofing

Water damage, water leakage and any seepage issues may seem minor at first but are largely detrimental to the health of your building’s structure. The need for holistic waterproofing is vital to the health and longevity of your building’s stability, structure, and hygiene Along with the right water leakage detection it is also important to find the right water leakage solution. Let us run you through a few long-term effects of water damage in your homes and buildings.

Health Hazards

Health Hazards

For the occupants of the building or home, a water damaged property is a breeding ground for low quality air and bacteria. If the water damage is not addressed correctly with proper waterproof solutions, the microbes and bacteria from the damage can be present in and outside the property causing harm to the health of others. This can lead to gastrointestinal issues and respiratory or skin-related issues and even severe issues if the water was contaminated.
Growth of Moulds

Growth of Moulds

Moulds are a product of long-term water damage or water leakage in your property. Growth of moulds can lead to unhygienic conditions and can give rise to serious illnesses. Treating mould growth may prove to be expensive as well if you ignore the issue early on. Moulds can lead to rotting of your building’s materials and can cause long term structural damage.
Structural Damage

Structural Damage

Bubbles, peels and stains on your building’s interior walls and exterior walls are a sign of water damage. This further leads to cracks and holes resulting in overall structural damage of the building. Water damage can split and warp dry walls causing paint damage as well. Raw materials used to create strong foundations like cement, concrete and others can also soak in water and store it for a long time, eventually leading to severe damage and costly fixes.
Water Stains and Property Damage

Water Stains and Property Damage

Water stains and blots look aesthetically unpleasant on your building walls. Discoloured walls and roofs or ceilings reflect poor structural hygiene of the building. Along with that, water damage may lead to property damage reducing the value of your property and its overall worth.

While we have studied the effects of severe water damage thereby implying the need for strong waterproof solutions, we should also be aware of the common sources of water infiltration to prevent it in our buildings.
Rainwater

Rainwater

Monsoons may lead to flooding in building premises or leakages through windows and roofs. Rainwater has a way of making its way through existing leaks, poor drainage systems, terraces and window sills. In fact, contaminated water may flood your building premises and breed serious illnesses and germs.
Ground Water

Ground Water

Groundwater is basically water that rises up from the soil and is a result of rain or snow. Groundwater infiltration is when the water rises and mixes with the drainage system. During monsoons, this can lead to flooding of the premises and severe damage to property and increase in health hazards.
Plumbing Leaks

Plumbing Leaks

Leaking pipes and issues with poor plumbing are one of the main sources of water infiltration. Pipes leak due to pressure, temperature and poor materials as well. Similarly faulty plumbing can also lead to water damage and leaks. Corrosion can also cause pipes to leak over time, especially if the building’s structure is old.

Surface Preparation

Surface Preparation

A clean surface is the first step to application of a waterproof coating. The cleaner the surface, the better the adhesion. A few ways to prepare your surface, be it roofs, external walls or terraces, is to ensure that visible cracks are repaired, organic growth is removed and cleaned with fungal repair solution and the substrate is cleansed. In cases of large external walls, power washers are recommended as it can clean quicker than manual cleaners.
Priming

Priming

Primers enhance adhesion. A primer is needed to smoothen the substrate and seal pores, bituminous surfaces, and to tackle corrosion in other materials. Priming provides a fresh start to waterproof coating. It blocks and seals any superficial damage on the walls. You can also seal cracks with Nerolac Perma Waterproof Putty.
Application

Application

Now that your area is primed. It is time to choose the tools for application. You can either go with a brush for small surfaces, a roller for inaccessible surfaces and sprayers for large expanses. With the tools, apply Nerolac Perma No Damp and No Damp+ to the affected areas. Applying the coat evenly is of utmost importance. Two coats can be applied as well for better adhesion on to the surface. Be mindful of the temperature while applying the waterproof coating and the weather as well.
Drying and Curing

Drying and Curing

Since waterproof coatings have thick membranes, it is of utmost importance to give it 6-8 hours to dry, Even an application of another coat should be done 3-4 hours after the first coat. Let the drying and curing process take its time for good results. The more time you give it to dry and cure, the better the coating and its effect on your wall.
