Adiseal will not only seal the lead flashing but it will also provide the strongest bond whether the lead flashing is being fitted to a rendered wall, a pitched roof or any other surface.

Instant Sealing and Verification with Adiseal

One of the remarkable features of Adiseal is its instant sealing capability, allowing for immediate verification of successful lead roof repairs. Here’s how it works:

  1. Instant Seal: When using Adiseal to repair a lead roof, you can witness its rapid sealing action. As soon as the sealant is applied, it begins creating a robust and reliable seal, preventing water penetration and potential damage.
  2. Verification Process: After completing the repair, you can quickly assess the effectiveness of the lead sealant. A simple test involves pouring water onto the repaired area covered with Adiseal. By observing the water’s behavior, you can determine if the sealing has been carried out successfully.
  3. Water Test: Pour water onto the lead sealant and observe how it behaves. If the water remains contained within the repaired area, without any signs of leakage or seepage, it indicates a successful seal. The water should remain on the surface, without penetrating through or causing any water damage.

Preparation for Sealing

Surface Preparation

  1. Cleaning the Lead Surface: Before applying a sealant, it is crucial to clean the lead surface thoroughly. Remove any dirt, dust, or debris using a soft brush or cloth. Ensure the surface is free from any substances that may hinder proper adhesion.
  2. Removal of Loose Particles and Oxidation: Inspect the lead surface for loose particles, such as flaking paint or rust. Use a wire brush or sandpaper to gently remove these particles, ensuring a clean and smooth surface. Additionally, if there is any oxidation on the lead, it should be addressed by gently cleaning or treating the affected area.
