How
- Prep the Surface: Scrub the area clean of dirt and grease. Patch any cracks/holes and create a small cement "slope" (fillet) along the corners where walls meet the floor.
- Wet the Area: Lightly dampen the surface with water. It should be moist but have no standing puddles.
- Mix: Slowly add the Powder (Part B) to the Liquid (Part A). Stir for 3 minutes until smooth. Use the mix within 30 minutes.
- First Coat: Use a stiff brush or roller to apply an even layer, ensuring you fill all tiny holes and gaps.
- Second Coat: Wait 4–8 hours for the first coat to dry. Apply the second coat cross-wise (at a 90-degree angle to the first) to ensure total coverage.
Note: Use 2 coats for bathrooms/balconies; 3 coats for water tanks. - Dry & Test: Let it cure for 24 hours. Before tiling, perform a "flood test" by filling the area with water for a day to confirm it is leak-free.
- Clean Up: Wash your tools with water immediately after use. Once the product sets, it can only be removed by scraping.
💡 Quick Tips: Do not apply to surfaces with active, running leaks. Fix the leak and dry the area before starting.
