Preparation for Sealing

Surface Preparation

  1. Cleaning the Lead Surface is a critical step before applying a lead sheet flashing sealant. Thoroughly clean the lead surface to remove dirt, dust, or debris using a soft brush or cloth. Ensure the surface is free from any substances that may impede proper adhesion.
  2. Inspect the lead surface for loose particles, such as flaking paint or rust. Gently remove these particles using a wire brush or sandpaper to achieve a clean and smooth surface. Additionally, address any oxidation on the lead by gently cleaning or treating the affected area.
