INTERNAL WATERPROOFING
(Treatment for Rising Dampness & Efflorescence in Interior Walls)
Walls inside homes often show signs of efflorescence, damp patches, and peeling paint, especially near wet areas like bathrooms, kitchens, or utility spaces. This is due to capillary action – where moisture rises from the foundation or external walls into interior plaster. WG Group offers targeted internal waterproofing systems to protect your interiors from such damage.
✅Why INTERNAL WATERPROOFING is Crucial
- Prevents white patchy deposits (efflorescence) on painted walls
- Avoids damage from rising dampness due to capillary moisture
- Extends the life of paints and finishes inside your home
- Essential for internal walls adjacent to wet areas
🛠 WG GROUP’S RECOMMENDED INTERNAL WATERPROOFING SYSTEM
- Polymer-Based Elastomeric Coating
High-performance coatings designed to resist negative water pressure and bridge micro-cracks.
- Single Component Pure Acrylic
Easy-to-apply, ideal for moderate dampness - Two-Component Cementitious System
Cement + Polymer mix, tougher and durable for high-damp areas
2. PU-Based System
Long-lasting, flexible and highly durable systems that protect internal walls, especially non-UV exposed areas (undercoats).
🔧 Surface Preparation Guidelines
- Scrape off paint and putty to expose raw plaster
- Clean surface with water 2–3 times
- Fill honeycombs, voids, and cracks with PMM or non-shrink mortar
- Measure moisture using a meter –
If using cementitious systems, surface must be in SSD (Saturated Surface Dry) condition - Choose material based on surface moisture level
✔ Features:
