A leak on a zinc gutter can be easily repaired. Performing the repair without waiting avoids having to change an entire section of the gutter.
- Sand the medium abrasive at the hole or crack, overflowing widely.
- Dust the zinc.
- Degrease the surface.
- Apply a layer of resin using a flexible spatula (repair kit).
- Immediately drop a piece of fiberglass.
- Apply a second layer of resin over it.
- Apply with a brush a layer of gel-coat (hardening resin) white or tinting to ensure tightness.
