Calder Lead Sheet Sealant - 290ml Tube

It is used for fixing lead sheets and flashings to masonry or brickwork, acting as a flexible and durable alternative to traditional mortar pointing.

No, it is supplied in a 290ml cartridge designed to fit standard caulking guns, which are widely available.

The sealant cures in atmospheric conditions. While it skins over relatively quickly, full cure time can vary depending on temperature and humidity. Always refer to the product packaging for specific curing times.

This sealant is not designed to be painted over. It is intended to provide a finished seal on its own.

The fungicide helps to inhibit the growth of mould and mildew on the sealant surface, maintaining a cleaner appearance over time.

The sealant is designed to be durable and weather-resistant once cured. However, it should be applied in dry conditions and within the recommended temperature range specified on the product packaging for optimal performance.

Store cartridges in a cool, dry place, away from direct sunlight and extreme temperatures. Once a cartridge has been opened, it is best to use the remaining product promptly, as it may start to cure.

Ensure the caulking gun is properly loaded and the trigger is being fully squeezed. Check that the cartridge nozzle has been cut and the inner seal pierced.

Verify that the surfaces were clean, dry, and free from dust, grease, or loose material before application. Ensure sufficient sealant was applied to make good contact.

Curing time is dependent on temperature and humidity. Ensure application is within recommended temperature ranges and check for excessive moisture or inadequate air circulation. Allow more time for curing in cold or damp conditions.

Practice applying a consistent bead on a scrap surface first. Smooth the bead immediately after application using a damp tool or finger before the sealant begins to skin over.
