In fact Adiseal was so strong, that the screws holding the test rig down started to rip out forcing the test on Adiseal to be stopped. The test can be watched on YouTube.

Adiseal will not only seal the lead flashing but it will also provide the strongest bond whether the lead flashing is being fitted to a rendered wall, a pitched roof or any other surface. Adiseal will also stick roofing felt to lead.

Seals instantly

As Adiseal seals instantly, it is possible to check whether repairing lead roof has been carried out successfully instantly. Once the repair has been carried out, pour some water on lead sealant to find out if it’s sealed the lead.

Provides a permanent seal

When using Adiseal to repair lead flashing, Adiseal will also provide a permanent fix as well as an emergency repair. If done correctly, the seal will last for years.

Permanently flexible

Adiseal stays permanently flexible meaning it will not become brittle. With temperature changes, items expand & contract. With this expansion & contraction, products that are not flexible become brittle and will crack or break causing water to leak through it. This is not a problem with Adiseal sealant & adhesive as is stays permanently flexible. The seal for lead flashing will last a lot longer than rival lead flashing sealants.

UV resistant

If the product is not UV resistant, there is a high chance it will fail very quickly. A roof is one of the main areas of a property where it will receive high UV radiation from the sun.

Solvent free

As Adiseal lead sealant is solvent free, it does not shrink once applied. This is a common problem with other products. For these other products to cure, the solvent have to evaporate away, causing the product to shrink and come away from the surface it has been applied to. Cheaper products tend to have more solvents leaving a weaker bond than Adiseal.

Another problem with solvent based lead adhesives & sealants is that the solvents will attack sensitive materials like polystyrene which is a common insulation material in building roofs, walls & other places.

Works in dry, wet & even underwater

As Adiseal works in dry, wet & even underwater, it’s possible to carry out an emergency repair on a leak even if it’s raining outside.

Lead sealant colours

Adiseal lead sealant & adhesive is available in a number of colours including grey to closely match the colour of the lead flashing. It is available in white, black, grey, brown & ultra clear.
