Waterproofing Guide
External walls are the first barrier against rain, wind, and moisture. If not properly waterproofed, they can lead to damp patches, peeling paint, mold growth, and even structural damage. Here's a simple guide to protect your walls for years:
1. Inspection of the Surface
Start by inspecting the external walls for cracks, damp patches, paint peeling, or efflorescence (white salt deposits). Early detection of problems helps in planning effective waterproofing.
2. Surface Preparation
Thoroughly clean the walls to remove dust, old paint, algae, and loose materials. A clean, dry, and stable surface is critical for strong adhesion of the waterproofing system.
3. Crack Filling
Fill all cracks using a crack filler or repair mortar. Even hairline cracks should not be ignored as they can allow water ingress over time.
4. Choose the Right Waterproofing System
External walls need elastic and UV-resistant waterproofing systems to handle thermal expansion and contraction. Suitable options include:
• Elastomeric waterproof coatings (acrylic or silicone-based)
• Flexible exterior-grade paints
• Anti-carbonation coatings for added durability
5. Application
Apply the waterproofing coating in 2–3 coats with a brush, roller, or spray. Ensure even coverage and adequate drying time between coats for best performance.
6. Proper Detailing
Special care should be taken around windows, doors, balconies, and other projections where leakages are common. Reinforce these areas with additional waterproofing layers or tapes.
7. Regular Maintenance
Inspect your external walls once a year, especially after monsoon, and carry out touch-ups or re-coatings if required to maintain long-term protection.

EXTERNAL WALL WATERPROOFING:
1. What is external wall waterproofing?
External wall waterproofing is the process of applying protective coatings, membranes, or sealants to prevent water penetration, seepage, and dampness on exterior walls. It helps protect buildings from damage caused by rain, humidity, and environmental conditions.
2. Why is external wall waterproofing important?
Without proper waterproofing, external walls can absorb moisture, leading to:
- Peeling paint and damp patches
- Growth of mold, mildew, and algae
- Cracks and structural damage
- Reduced lifespan of the building
Waterproofing ensures long-term durability, maintains aesthetic appeal, and reduces maintenance costs.
3. What types of external wall waterproofing solutions does ADT Industries Pvt. Ltd. offer?
We provide a range of waterproofing solutions, including:
- Acrylic Polymer-Based Waterproofing (e.g., Dr. Fixit Raincoat – a high-performance elastomeric coating that forms a thick, flexible waterproof film on walls.)
- Silicone-Based Water Repellents (e.g., Dr. Fixit Repellin WR – a transparent coating that prevents water absorption while allowing walls to breathe.)
- Elastomeric Waterproof Coatings (e.g., Sikalastic 560 – a UV-resistant, crack-bridging waterproof coating ideal for external walls exposed to extreme weather.)
- Cementitious Waterproofing (e.g., Fosroc Brushcrete – a flexible, cement-based waterproof coating that bonds well with plastered surfaces.)
4. How can I tell if my external walls need waterproofing?
Common signs that your walls need waterproofing include:
- Damp patches or water stains on exterior or interior walls
- Peeling or blistering paint
- Cracks on the wall surface
- Growth of algae or fungus, especially in humid areas
5. Can waterproofing be applied to already painted walls?
Yes, but it is recommended to remove old, damaged paint and properly prepare the surface before applying waterproofing coatings for better adhesion and effectiveness.
6. How long does external wall waterproofing last?
The longevity depends on the product used and environmental exposure.
- Dr. Fixit Raincoat can last up to 8-10 years with proper application.
- Sikalastic 560 provides long-term protection of up to 10 years against rain and UV rays.
- Dr. Fixit Repellin WR offers 5-7 years of water repellency before requiring reapplication.
7. Does waterproofing affect the appearance of my walls?
No, waterproofing coatings like Dr. Fixit Raincoat and Sikalastic 560 come in various shades and enhance the aesthetic appeal of walls. Transparent coatings like Dr. Fixit Repellin WR maintain the natural look of surfaces while protecting them from water damage.
