In order to make your roof waterproof in Karachi, you need to follow these 4 easy steps.
TOOLS
- Broom
- Spatula
- Roller
- Brush
- Plastic cement
- Water
- Detergent
- Acrylic sealer
- Acrylic waterproofing
STEP 1
The first step you should do is clean the entire ceiling. It is important that it is completely clean and free of grease, dust, and fungi stains; as the waterproofing needs a clean surface to adhere to. To do this, scrub the surface with the help of a broom, water, and detergent. Rinse as many times as necessary and allow the surface to dry completely.
STEP 2
With the roof clean, we will repair all existing cracks and chips. With the help of the spatula, remove all the chipped concrete, and apply a layer of plastic cement. In this way, the waterproofing will achieve good adhesion.
STEP 3
When your ceiling is clean and free of cracks, apply an even coat of acrylic sealer with the help of the brush. Its function is to adhere the waterproofing to the surface. Do not apply the sealer in case rain is forecast. Let dry for 12 hours and remember not to let more than 24 hours pass, this will prevent the sealant from getting contaminated.
STEP 4
With the help of the roller, pass the acrylic waterproofing without exerting too much pressure over the entire area, in order to be uniform over the entire surface. Once the first coat is dry, apply a second coat following the same advice. Don’t overlook weak spots, like cracks, drains, and telephone or television installations. Finally, with the help of the brush, reinforce the contours with one more layer of waterproofing.

Tip # 1 Ask your client about the use that will be given to the property and what warranty time it requires
This is the starting point to establish the range of materials suitable for what the client is looking for. It may be that the client only needs to protect his property for a year because he is already moving and in that case he would occupy a very basic and not so durable protection.
Tip # 2 Check if it is a new roof or if it already has a waterproof system
In new slabs, most of the systems can be installed without problem, but in those that require re-waterproofing or maintenance, special care must be taken so that the new system is compatible with the existing one, or failing that, completely scrape the material current until you reach the concrete slab.

Tip # 3 Check if the slab is flat or sloping
Emulsified waterproofing systems are not suitable on a flat slab, (either acrylic or asphalt) as minimal ponding can re-emulsify the system. In these cases, a prefabricated or polyurethane system is needed.
Tip # 4 Ask your client if the roof will have sporadic or continuous pedestrian traffic
This variable is very important to determine if it is necessary to use a simple or reinforced system or to include the design and installation of traffic corridors.
Tip # 5 Take into account the weather conditions of the place
If you are going to work in a geographical area where extreme cold or heat prevails, you must use materials specially designed for these climatic conditions.
Tip # 6 Make sure the roof surface is completely clean before starting work
It is very important that in any system that is going to be installed, the concrete surface is healthy, free of grease, dust, loose or poorly adhered parts; cracks are repaired, as well as penetrations and downspouts are reinforced with banding of waterproof material and polyester fabric.
In cases where there are large holes or puddles, it is necessary to make a filling.
Tip # 7 Make sure you buy a good quality waterproofer from reputable manufacturers
Each manufacturer performs laboratory tests to determine the life of their waterproof systems and based on these results, the warranty period is established, and in turn, future maintenance or renovations are calculated based on this warranty.
It is important to mention that each manufacturer performs the same type of test to determine the warranty of its product, but where they differ is in the “safety cushion”, that is, the ethical manufacturer performs the test and if the results stipulate that the material lasts 5 years outdoors, manages a safety margin, and instead of labeling with a 5-year warranty, labeling it with 3 years. Manufacturers of low-priced, low-quality products do not use this margin and typically label for 5 years.
This is why it is important to find and select waterproofing contractors who work with materials from ethical manufacturers. If you are working with materials where the manufacturer did not use a safety margin, it is very likely that maintenance or renewal of the waterproofing will be necessary long before the labeled warranty period.
