Firstly, there is no ‘one-size-fits-all’ approach to waterproofing. For instance, did you know that there are special products to seal and waterproof the masonry joints around door frames, window frames and switchboards, and different ones for sanitaryware, glass and metal joints? That’s the thing about waterproofing—if it’s not done right with specialised products to address different problem areas, it could be a wasted exercise. The Asian Paints website has a host of information/videos on the application products and recommended products to treat different areas of your home. We suggest you look up and read all you can. As for all those questions buzzing on top of your mind right now, we got answers straight from the experts:
First things first, is damp-proofing the same as waterproofing?
No, waterproofing covers more areas and issues like cracks and gaps, tiling, paint peeling and efflorescence; it also strengthens the concrete.
Should waterproofing be done along with painting?
No. To get the best results, waterproofing should be done before painting. In case of moderate/severe dampness/leakage, it should be addressed immediately.
How long does the process take?
It depends on the nature of treatment. In case of new construction, three to five days. In case of old structures or repair work, keep more patience in hand—it will take at least two weeks.
How long will the effects last? Do I need to do it every year?
If the source of the dampness/leakage is properly cured, you won’t need to do it till the next home painting cycle.
Okay, so when is the best time to start the waterproofing process?
Ideally, when your house is being constructed. It’s the failproof way to ensure that new or small leakages/dampness don't become a bigger hindrance in the future.

What kind of properties are more susceptible to water seepage issues?
Independent homes, bungalows and top floors of buildings are more susceptible to water seepage due to weather conditions and expansion/contraction of external surfaces.
Is the treatment the same for apartments and bungalows?
No. Besides a lot more external waterproofing, bungalows also need heatproofing to reduce surface temperature. Bungalows are also vulnerable to rise in groundwater level, which causes dampness in walls.
If you live in an apartment, you need to focus on protecting the top coat paint from surface dampness arising from areas like bathrooms/kitchens.
Which parts of my house are more likely to be problem areas?
Every corner that is prone to leakage/dampness—bathrooms, basement—as well as the parts that are exposed to rain—terrace, water tanks and vertical walls. For areas that are likely to develop cracks and gaps, measures can be taken to ensure that they don't arise by accounting for them during the construction phase itself.
What should I be aware of about waterproofing at various stages of construction?
Read as much as you can about the variety of products that are available to treat different problems that are unique to different areas of your house. For instance, terraces and exterior walls don’t just need waterproofing and heat proofing but also need to be treated with products that can bridge cracks. For example, in case of sunken slabs in bathrooms/walls adjacent to bathrooms, Asian Paints offers products such as DampBlock2K that can be added as a preventive coating against leakages.
Asian Paints also offers Vitalia Neo, an integral waterproofing compound, which is mixed with cement at the time of construction to provide a basic level of waterproofing and also strengthens concrete.
What if I don’t want to go through all these hassles? Are there any quick fixes?
Unfortunately, there are no quick fixes. If the surface is treated but the source of the leakage is not identified and sealed, the damages will be visible again in a couple of months.
Is there a waterproofing warranty cover? What will it offer?
Yes. A warranty offers the assurance of product performance if applied as per the requisite guidelines.
The big question: how much does it cost?
The costs vary as per nature of the issue or construction. It could range anywhere between Rs. 10/sq. ft. to Rs. 40/sq ft.
Where can I find competent applicators?
Contact the experts at Asian Paints. They can identify and help solve the problem via expert application of specialised preventive and curative products. You could also avail of services like masonry, plumbing, tile fixing and tile grouting based on what you need.
