It suits moisture-prone areas such as bathrooms, kitchens and rain-exposed exterior walls, and protects against flaking, peeling and moisture damage. One 30 kg bag covers about 450–600 sq ft in two coats. Mix with 36–38% clean water, keep the total thickness within 1.5 mm, and use the mix within 3 to 3.5 hours.

Application Guidelines

Why Buy from HomeRun?

1) What makes WallSeal different from regular WallCare Putty?

WallSeal has 2X enhanced water resistance from Active German Silicon Polymers, which suits moisture-prone areas. WallCare is a standard interior putty without enhanced waterproofing. Use WallSeal for bathrooms, kitchens and exteriors, and WallCare for dry interior walls.

2) Can I use WallSeal Waterproof Putty on exterior walls?

Yes. It is designed for both interior and exterior use, and its enhanced waterproofing makes it a good fit for exterior walls exposed to rain, humidity and weather.

3) Do I still need waterproofing treatment after using WallSeal?

WallSeal gives a water-resistant putty layer but is not a complete waterproofing system. For critical areas such as bathrooms and terraces, apply a dedicated waterproofing membrane first, then WallSeal. For general moisture protection, WallSeal alone is sufficient.

4) How much water do I add, and how long does the mixed putty last?

Add 36–38% clean water by weight, which is 10.8–11.4 litres for a 30 kg bag. The mixed paste stays usable for 3 to 3.5 hours at most. After that it breaks down and must be thrown out.

5) How thick can I apply it, and how long between coats?

Keep the total thickness within 1.5 mm across both coats — a thicker build traps tension in the cement and causes shrinkage cracks and paint peeling. Wait 3 to 4 hours before the second coat. If you need to sand, use ultra-fine waterproof emery paper of not less than 500 grit so you don't scratch off the water-repellent layer.

6) Can I use WallSeal in swimming pool areas?

Not recommended for direct water immersion or constant water contact. WallSeal is designed for moisture resistance, not submersion. For swimming pools, use a specialized pool-grade waterproofing system with tile finishes.

7) What primer should I use after WallSeal?

Use Birla White ActivCoat Primer (interior or exterior) or any quality water-based primer compatible with waterproof putties. Primer seals the surface, improves paint adhesion and supports the overall waterproofing system.
