Review: The best sealant to use with lead - The best stuff for sealing lead into brickwork. Really good quality neutral cure silicone. Sticks well and cures good enough within 24 hours. Make sure to clean out the brickwork joint, and also clean the lead with meths before applying the Lead Mate.
Review: Takes longer to skin and cure than it says! - OK, but takes way longer to skin and cure than stated. In dry, medium humidity, applied at 17C, down to 11C at night, it took six hours to skin (not 15 minutes!) and not come away on the fingers when touched, and a full 11 hours to cure so that it was medium firm (not the full cure, that will likely be a couple more days).

## Features

- Causes serious eye irritation.
- VERSATILE – Works as an alternative to mortaring lead flashing and sheet into brick, stone and concrete. Use it for weather sealing and joint sealing to pre-formed panels and for roof weather sealing applications.
- EXCELLENT ADHESION – This flexible sealant offers superb adhesion and will not stain cement or corrode soft metals like lead, copper and zinc, unlike most conventional sealants.
- LOW SHRINKAGE – Excellent flexibility of +/- 25% and less than 5% shrinkage during vulcanisation. Also offers low and high-temperature resistance from -50°C to +150°C once fully cured.
- RESISTANCE TO PLASTICISER MIGRATION – This grey sealant has high resistance to plasticiser migration so may be used over water-based and solvent-based paints.
- EU CERTIFIED – Certified under the harmonised European standard EN15651 for use on façade, interior, exterior and for cold climate applications. Complies with EU Construction Products Regulation.

## Questions & Answers

**Q: Can the product effect a seal between fibre glass reinforced plastic and bitumen painted plywood? Is the cured product compatible with bitumen paint?**
A: Hi, this item has excellent adhesion to polyester and plastics including pvc. Might be a problem on items that bleed oil and its says do not use in conjuction with bitumen or asphat.(use weather mate)

**Q: Does it bond lead pvc and brick**
A: You bet but make sure that the brick work is clean before applying and press it well on to the brick work. I used it on a split in some lead work over brick which had caused a leak in heavy rain around 10 years ago and it was still doing it's job last time we had some heavy rain, great product.

**Q: Would it 'stick' two pieces of lead together-so I don't need a gas gun etc**
A: I used it with IVO lead substitute flashing and it does stick that together very well.Not tried it with lead.

**Q: Is this any good between conservatory and brick wall to fill a gap?**
A: Yes. I am assuming you are filling the gap between the brick and lead flashing?
It is a good strong sealer
