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.
