What Makes Everbuild Lead Mate a Special Choice Compared to Other Alternatives in the Market?

In the world of construction, particularly in roofing, the choice of materials can significantly impact the durability and effectiveness of the work. A critical aspect of this is the installation of lead flashing, a process traditionally dependent on mortar. This is were lead mate sealants come in but more on that later.

Mortar is a paste which hardens to bind stones, bricks and concrete masonry units in buildings. It includes pitch, ashpalt and soft mud or clay.

However, mortar has shown limitations, especially in its lack of flexibility, leading to cracks and breakages under extreme temperatures. This is where Everbuild Everbuild Lead Mate sealant steps in, revolutionizing the method of installing lead flashing.

Revolutionising Lead Flashing Installation

Everflex Lead Mate Sealant is not just another sealant. It's a specialised solution that overcomes the shortcomings of traditional mortaring. This low modulus, neutral cure sealant boasts exceptional adhesion to soft metals. It includes lead and brass, a common challenge with general sealants.

Key Features of Everbuild Lead Mate Sealant

Exceptional Metal Adhesion

Its primary advantage lies in its ability to bond effectively with soft metals, which is crucial for securing lead flashing in place.

⁠Flexibility and Durability:

The sealant offers an impressive flexibility range of +/- 25%. It can withstand various environmental changes without losing integrity. Its resistance to extreme temperatures (both low and high, up to +150°C) further enhances its suitability for various roofing applications.

Low Maintenance

With its low dirt pick-up quality, the sealant maintains a cleaner appearance over time, reducing the need for frequent cleaning.
