Waterproof Coating

Choosing points
- Best for roofs, balconies, and wet areas where the visible finish represents a waterproofing layer.
- It often has upturns at walls, drains, and thresholds.
- Topcoat color fades and chalks under sun.
- Ponding water leaves rings, dirt, and algae near drains.
How it ages
- UV, standing water, substrate cracks, poor drainage, and mechanical damage can cause cracking, blistering, or leaks.
What to avoid
- Do not expect waterproof coating alone to fix poor slope, poor drainage, water entry points, or weak waterproofing edges. Water still needs a way out.
