The ALM Premium Flashpoint Lead Sheet Sealant offers a superior alternative to traditional mortar for lead-brick and lead-masonry joints, designed to resolve common issues like cracking and poor adhesion.

This innovative silicone-based sealant provides a permanent, flexible, and waterproof joint that can withstand temperatures ranging from -65C to 165C, making it suitable for use in diverse climates. Its neutral cure formula effectively prevents the unsightly white stains that can appear on lead when using acidic products. With a service life of up to 20 years, Flashpoint guarantees lasting durability and reliability. Its application is cleaner, quicker, and easier than mortar, with strong adhesion to both lead and masonry, enabling seamless application even in cold, frosty conditions.
