Case study of a 48‑storey luxury tower at Mahalaxmi in Mumbai

Project Overview and Challenges for a 48‑storey luxury tower at Mahalaxmi in Mumbai

Standing at 648 feet on a verdant five‑acre plot in Mahalaxmi, Mumbai, this 48‑storey luxury tower by one of India’s leading builder presented more than just an impressive skyline silhouette.

Behind its gleaming facade lay a real challenge: monsoon‑season downpours, relentless humidity, and scorching heat can all conspire to turn concrete walls into water traps.

The design and construction teams needed a solution that didn’t just look elegant – it had to lock out moisture for decades without peeling or cracking.

How Sunanda Global Became Their Go‑To Partner

At first, the architects and contractors had seen plenty of “miracle” products that underperformed on real sites.

Sunanda Global knew talk alone wouldn’t convince them.

So, we brought on‑site demos and real‑world case studies.

Our tech team guided every step, from mixing ratios to trowel techniques.

By the end of our first meeting, they weren’t just clients – they were collaborators, confident that our system would deliver exactly what they needed.

Why Three Coats Make All the Difference for this 48‑storey luxury tower

Early on, we knew a single coat wouldn’t cut it.

So, we recommended a three‑step acrylic system that works like a layered defense:

Acrylic polymeric cementitious waterproofing coatings form a rock‑solid barrier directly bonded to the concrete. Mixing our concentrate with cement yields a seamless, scratch‑resistant film that seals pores and holds fast under stress.

Acrylic textured exterior coatings add both beauty and toughness. That 2–3 mm sand‑finish doesn’t just look rich – it hides tiny blemishes and bridges hairline cracks. Plus, its flexible resin content fights off mold and carbonation, keeping walls fresh.

Acrylic waterproofing exterior coatings top everything off with a high‑build acrylic layer. This layer stretches with the building as temperatures swing, seals remaining micro‑cracks, and shrugs off wind, rain, UV rays, and even algae.

Together, these three layers create a continuous shield that lives up to the building’s premium promise.

Rolling Out the Coatings – A Step‑by‑Step Journey

Here’s how we turned plans into a watertight reality:

Meticulous Preparation: The skilled applicators blasted off form‑release agents, cleared the dust, and patched tie‑rod holes with polymer‑enhanced grout. A flawless surface meant fewer surprises later.

Primer & Base Coat: A quick‑dry bonding primer locked in adhesion. Then, two coats of acrylic‑modified cementitious slurry paved the primary waterproof barrier. It cured fast and bonded like glue.

Mid Coat Magic: Applying the textured finish felt almost creative – like sculpting with sand cream. In just 12–16 hours, the walls transformed from flat concrete to rich, tactile surfaces.

Final Seal: The applicators rolled on two coats of our acrylic waterproofing topcoat, each requiring a short rest period. When the coats dried, the surface shimmered slightly – a visual cue that every pore and crack was sealed.

Our crew stayed on schedule and seamlessly integrated with other trades.

Real‑World Results That Speak Volumes for a 48‑storey luxury tower

When the first monsoon clouds rolled in, the project team gathered for a simple test: water spray.

Not a single drop seeped through.

Months later, walls remain unblemished – no stains, peeling, or mold.

Residents enjoy dry, comfortable interiors. And for facility managers, the savings are real: no emergency waterproofing fixes, no mid‑monsoon headaches.

Durability: Years of monsoon cycles ahead with zero cracking or fading.

Aesthetics: A uniform, upscale texture that resists dirt and algae.

Peace of Mind: Proven performance means low maintenance and happy homeowners.

Lessons for High‑Rise Success

Sunanda’s protective treatment for the external walls of the above luxury tower taught us three big lessons:

Layering Wins: One coat won’t withstand Mumbai’s extreme climate. Three targeted layers do.

Teamwork Early On: Bringing reputed material consultants into the planning room avoids costly mid‑project changes.

Hands‑On Support: On‑site coaching and quality checks turn good products into great outcomes.

Conclusion

Crafting a luxury tower’s external facade is as much about chemistry as it is about collaboration.

By blending acrylic polymer cementitious coatings, textured finishes, and waterproofing topcoats, we helped the developers form a watertight, long-lasting, and visually striking envelope for the 48-storey tower in Mumbai.

At every stage, our team stood shoulder‑to‑shoulder with the builders.

The result? It is a landmark that not only defines Mumbai’s skyline but stands up to its fiercest monsoons – just as everyone involved hoped.
