Say Goodbye to Terrace & Roof Leakage
Water leakage during the monsoon often starts from small roof or terrace cracks. If ignored, these cracks can allow rainwater to penetrate deeper into the concrete, leading to damp walls, ceiling damage, and expensive repairs.
Waterseal Instant Crack Filler Kit penetrates deep into the crack, creates a strong waterproof seal, and helps prevent future water ingress. It offers a simple, cost-effective solution for repairing leakage-prone cracks without hiring a professional or damaging your existing terrace.
What’s Included in the Kit?
- 2 kg PSV Premix Crack Filler
- 50 ft PPC Reinforcement Strip
- 2″ Application Brush
- 4″ Putty Knife
- Step-by-Step Installation Guide
Everything required to complete the crack repair is included in one kit.
Crack Filling Application Process
Follow these simple steps for effective crack sealing:
Step 1: Roof & Wall Crack Surface Preparation
Use a hand scraper or angle grinder to clean the crack area and remove loose particles, dust, or old residue. This helps the crack filler bond properly with the surface.
Step 2: Prepare the Material
Mix the premix crack filler with water as instructed. You can use a plastic cup or container for mixing.
Step 3:Waterproof Crack Filling Application
Fill the crack groove completely using the putty knife, ensuring the material reaches deep inside the crack.
Step 4: Crack Sealing & Reinforcement
Place the PPC mat over the filled crack and apply a coat of filler using a brush. This step strengthens the crack joint and improves waterproofing durability.
Once cured, the crack forms a strong, waterproof seal that prevents future leakage.

I ordered PPC Mat and I got it in 5 days. But then I realized that this mat is not self adhesive. It works only with PSv chemical. Then I ordered PSv – PREMIX kit with which I filled every small crack on my roof. I have had it for two years but now there is no leakage. I saved Rs. 30000/- by spending only Rs. 2499/-.
