3 x Sika Lead Mate Lead Flashing Sealant Grey Everbuild

Sika LEAD MATE Sealant Lead Flashing Seal | Grey | Waterproof | Pack of 3

Lead mate sealant is specially formulated as an alternative to mortaring lead flashing and sheet into brick, stone and concrete, providing a fully waterproof joint that will not crack or shrink.

Application

Joint design should be as follows : Minimum width is 6mm. Movement capacity will be impaired if the depth of the joint is greater than the width. For maximum movement accommodation, it is recommended that the joint depth should be no less that 5mm. The joint depth should be 5mm for joints up to 10mm wide. Joints above 10mm in width should be half the width in depth up to 20mm and minimum 10mm for wider joints.

Maximum joint width without slumping is 40mm. When flashing into cocrete walls with a wider joint, always fix the lead with stainless steel screws and plugs prior to applying the sealant.
