Interior Wall Waterproofing

Interior walls are often affected by moisture due to leaking terraces, bathrooms, external wall seepage, or faulty plumbing. Over time, this leads to damp patches, mold growth, peeling paint, and unpleasant odors—damaging both your home’s appearance and your family’s health.

At Rainexa Waterproofing Solutions, we offer specialized interior wall waterproofing services that treat the root cause of dampness and protect your walls from the inside out.


Why Interior Wall Waterproofing is Important

Moisture infiltration into interior walls can cause:

  • Dampness and discolored patches

  • Peeling or bubbling paint

  • Mold and mildew growth

  • Plaster damage and wall softening

  • Increased risk of allergies or respiratory issues

  • Cracks and structural weakening over time

These problems not only affect the aesthetics of your space but also its safety and hygiene.


Our Interior Wall Waterproofing Process

At Rainexa, we follow a proven method to ensure your interior walls are fully sealed and protected:

1. Moisture & Leak Detection

We inspect the affected area and use moisture meters or thermal scanning to locate the exact source of water seepage.

2. Surface Cleaning & Preparation

The wall surface is scraped and cleaned to remove loose paint, plaster, and fungal deposits.

3. Crack Filling & Repair

All visible cracks and holes are filled with waterproof crack fillers or polymer-modified mortar to ensure a strong base.

4. Waterproof Coating

We apply interior-grade waterproofing coats, such as:

  • Cementitious waterproofing slurry

  • Acrylic-based waterproofing primers

  • Anti-microbial, moisture-resistant interior wall coatings

Multiple coats are applied for long-lasting protection and breathability.

5. Final Finishing

The wall is left with a smooth finish, ready for repainting or wallpapering, depending on your interior decor needs.
