Lead Pointing Sealant

The most common reason for water penetration is failure of the mortar used in pointing the joint between the Lead and brickwork or masonry. This is due to the inability of the mortar to contract and expand at the same rate as the Lead during any temperature changes. In extreme cases the pointing will crack and allow water to penetrate the joint and subsequently causes damage and dampness within the building fabric.
