How to fix leaky gutters
Because they’re directly exposed to harsh environmental conditions, even the toughest gutters can develop cracks. This can also happen if the sealant dries out and splits over time. Here’s how to caulk gutters and repair gutter cracks using glues and sealants designed for durable bonding in outdoor conditions.
1. Prepare the gutter. Again, it’s essential that the area to be fixed be clean of leaves and other debris. Use protective gloves and exercise safety when using ladders or climbing roofs.
2. Prepare the sealant. Many factors play a role in choosing the right sealant for gutter leak repair. Common product features considered by gutter leak repair professionals include:
- Resistance to water and moisture
- Drying time
- Ease of application
Loctite PL Roof and Flashing Polyurethane Sealant meets all these criteria and more. It’s a commercial-grade sealant formulated for sealing exterior gaps and joints. Flexible even after application, it’s resistant to weather, UV radiation, moisture, and corrosion and creates durable seals on most gutter types.
3. Apply the sealant. Force the sealant into the crack using steady pressure. The depth of the sealant applied should be about half the width of the fissure. The sealant will “skin” over the crack and dry within 24 hours. The gutter will be functional within three days, but full cure requires about a week. Cut away any cured sealant overflow with a sharp-edged tool.
