How to Waterproof Old Building Terrace?

Waterproofing the terrace of your old building can be a bit challenging for you since the surfaces are cracked or ruff. This means that the water will either pool up or move slowly above the surface during the monsoon, increasing the chances of leakage.

Seepage and leakage are mainly caused due to damages or cracks on the terrace slab, malfunctioning rainwater harvesting system, etc. But you can easily prevent such issues by opting for Scientific Waterproofing, which can prevent such water leakages.

Waterproofing the Old Building Terrace: How to Do It?

When you have decided to waterproof your terrace building, there are several steps that you must follow. Following the steps correctly will provide you with a positive outcome. These steps are:

Step 1: Cleaning/Washing

First, with a pressure washer or a brush, you must eliminate all the impurities, such as oil, dust particles, grease, and decomposed fungi/algae. Be sure that the terrace is completely clean. You can also use the Moisture Meter to check the dampness on the terrace walls before proceeding further.

Step 2: Strengthen or Fix All the Weaken Substrate

If you come across loosened plaster or concrete on the old building terrace, make sure to re-plastic and re-concrete it. You should leave the fixed areas to dry for at least 3 days. Once it becomes dry, you can easily wash or brush away all the dirt and dust from the area.

Step 3: Apply the Primer

The primer is the bonding agent between the surface and the coating. It ensures excellent adhesion and also increases the durability of the coating. Besides that, the primer also helps in offering an extra layer of protection to the surface of the terrace.

Step 4: Apply the Base Coat

Applying the base coat is extremely crucial, and it’s also the main part of all coatings. It directly affects the functionality and performance of the coating system. It builds a foundation for the coating to absorb all the movement shocks, which might occur due to external movement or by the surface.

Step 5: Apply the Reinforcement

Applying reinforcement within the system will add life to the coating system and expand the coating’s performance level. It can also prevent crack bridging with the coating failure.

Step 6: Applying the Intermediate Coat

Intermediate coatings carry a different purpose, adding all the extra protection level, isolation and insulation to the coating system.

Step 7: Apply the Topcoat

The top coat is the top level of the waterproofing system. It contains numerous properties, such as aesthetically pleasing, UV stable, solar emotive and reflective, anti-abrasive and anti-static.

Once you have completely applied all the coatings, you have to let it sit for half an hour, and it requires 24 hours to complete the curing. Make sure to apply around 2mm to 3mm layers of coating to prevent leakage.

Final Thoughts

Waterproofing has become the best option when you’re planning to improve the terrace of your old building. Applying polymer coating on a slab or concrete surface will make the entire terrace damage free and durable. If you wish to turn your terrace into a garden or any other thing, waterproof it properly.
