Forms a flexible, weatherproof seal that won’t crack or peel.

| Surface Type | Typical Applications | Tips for Best Results |
|---|---|---|
| Metal Gutters & Flashings | Sealing joints, cracks, and leaks | Clean surfaces well before applying. |
| Concrete & Tiles | Repairing roof cracks and sealing gaps | Apply in continuous beads for a watertight seal. |
| Roofing Materials | Sealing around vents, pipes, and overlaps | Use a caulking gun for neat, controlled lines. |
Make sure all surfaces are clean, dry, and free of grease, dust, or any loose paint. If painting is required, finish it prior to applying the sealant.
Cut the nozzle of the cartridge at a 45° angle and place it into a caulking gun. Dispense the sealant evenly along the joint or crack, ensuring it makes good contact with both surfaces.
Within 5–10 minutes of application, smooth the sealant using a spatula or a finger dipped in soapy water to achieve a tidy finish.
Allow the sealant to cure completely over 5–7 days. Keep the area free from water for at least 4 hours after application.
For best results, apply the product when temperatures are between 5°C and 40°C.
