If you’ve ever battled unsightly patches of dampness or powdery salt deposits (efflorescence) on your interior walls, you’re not alone. These are common signs of moisture seeping through walls — and they can be more than just an eyesore. They often signal deeper structural issues and can compromise the long-term health of your walls. Thankfully, Asian Paints SmartCare Hydroloc Xtreme offers a powerful and effective solution.
What is SmartCare Hydroloc Xtreme?
Asian Paints SmartCare Hydroloc Xtreme is a single-component, ready-to-use, film-forming interior waterproofing solution. It’s designed for ease of application and comes in a white, viscous liquid form. This brushable product forms a breathable yet watertight film on your interior walls to stop moisture in its tracks.
What Does It Do?
This advanced waterproofing solution tackles two major interior wall problems:
Dampness – caused by water seepage through walls.
Efflorescence – the white, powdery salt deposits left behind by moisture movement.
Hydroloc Xtreme blocks the movement of water and salts through porous materials. It imparts water repellency to the substrate while still allowing the surface to breathe. It also boasts the ability to resist up to 5 bars of negative hydrostatic pressure, which speaks to its heavy-duty waterproofing capability.

How to Apply: Best Practices for Success
Proper application is key to achieving the best results with SmartCare Hydroloc Xtreme. Here are the essentials:
✅ Surface Preparation:
The wall must be firm, clean, and free of oil, fungus, or loose materials.
Any existing efflorescence should be fully cleaned.
Repair all cracks and damaged areas.
Remove existing putty completely down to the plaster.
✅ Surface Condition:
Ensure the surface is in a Saturated Surface Dry (SSD) condition—moist but not wet—before application.
✅ Number of Coats:
Damp or efflorescent walls: Apply one diluted coat first, then a second undiluted coat after 6-8 hours.
Sound walls: A single undiluted coat is enough.
✅ Mandatory Putty Application:
Once Hydroloc Xtreme is applied and dried:
You must apply Asian Paints SmartCare Waterproofing Putty (or approved options like Trucare Wall Putty, Trucare Acrylic Wall Putty, or Trucare 2X Putty Primer).
Do not use handmade or Lambi putty under any circumstances.
⏱ Drying Times:
6–8 hours between coats of Hydroloc Xtreme.
4–8 hours for the waterproofing putty before sanding and painting.
Limitations & Safety Warnings
❌ Not for live leaks or rising groundwater – these sources of water must be addressed before using the product.
❌ Avoid using in conditions below 10°C or in high humidity (>90%) to prevent performance issues.
❗ Ensure good ventilation during application and wear eye protection and a mask during sanding.
❌ Do not dispose of the product in drains or ingest it—seek immediate medical attention if swallowed.
