Product description
Flexible pointing for lead flashing
ALM Premium Flashpoint is designed for the joint where lead flashing meets brickwork or masonry. It offers a flexible alternative to mortar pointing, which can crack as lead and masonry expand and contract at different rates. Its neutral-cure, silicone-based formula adheres to lead and masonry and cures to a waterproof seal. The sand colour offers a discreet finish against suitable masonry.
Why choose Flashpoint?
- Made for lead-to-masonry pointing at flashing chases
- Flexible seal accommodates thermal movement
- Neutral cure avoids the white lead staining associated with acid-cure sealants
- Waterproof finish for exposed pointing joints
- Approximately 5m coverage per 310ml cartridge in a 6 × 12mm joint
Application: Remove old mortar and make sure the lead and masonry faces are completely dry and free of dust. Secure the lead mechanically in the chase, fill the joint to the required depth, then smooth the sealant before it skins. Follow the manufacturer’s joint preparation instructions for the specific flashing detail.
