Seal Lead
Adiseal Lead Sheet Sealant: Grey Lead Seal
Adiseal lead sealant will both stick and seal lead flashing. When it comes to seal lead flashing, there are numerous products on the market. While certain lead sealants may provide temporary solutions, their effectiveness tends to diminish over time. In this discussion, we will explore the reasons behind this issue and highlight why Adiseal stands out as the superior choice for sealing lead, as well as adhering to and securing lead flashing.
Best sealant for lead flashing
The reason why Adiseal is the best lead sealer & adhesive is because Adiseal:
- Strongest adhesive
- Seals instantly
- Provides a permanent seal
- Stays permanently flexible
- UV resistant
- Cold applied
- Resists mould growth
- Solvent free
- Waterproof sealant
- Waterproof adhesive
- Works in dry, wet & even underwater
Strongest Adhesive
As well as Adiseal being a great sealant, it also proved to be the strongest adhesive in an independent adhesive strength test by Ultimate Handyman. In the test Adiseal was over 3 times stronger than the nearest competitor. Further details of the test are on the Adiseal page.
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
Adiseal seals instantly, allowing for an immediate check of lead roof repairs. After completing the repair, test it by pouring water on the lead sealant to confirm its success.
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 lead seal will last for years.
Permanently flexible
Adiseal remains permanently flexible, unlike products that become brittle due to temperature-induced expansion and contraction. Brittle products can crack or break, leading to water leaks. Adiseal’s enduring flexibility ensures a longer-lasting seal for lead flashing compared to its competitors.
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
Adiseal lead sealer, being solvent-free, avoids the common issue of shrinkage seen in other products. These products require solvent evaporation for curing, causing them to shrink and detach from the surface. Cheaper options often contain more solvents, resulting in weaker bonds compared to Adiseal.
Solvent-based lead adhesives and sealants can also harm sensitive materials like polystyrene, commonly used in building insulation for roofs, walls, and other areas.
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. It’s possible to carry our sealing lead even with rain pouring 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.
Other uses
Adiseal is a muti-purpose product & will also fix a leaking gutter & repair a felt roof.
How to seal lead flashing
How to seal lead flashing.
- Prepare the Surface
Ensure the lead surface is clean, dry, and free from dust, dirt, or any contaminants. Use a wire brush or sandpaper to remove any loose particles or oxidation from the lead surface. Wipe it down with a clean cloth to ensure it’s completely clean.
- Apply the Sealant
Cut the tip of the sealant tube at a 45-degree angle, making a small opening. Insert the tube into a caulk gun or use a squeeze tube if applicable. Apply a bead of sealant along the desired area you want to seal, such as joints or gaps.
- Smooth and Shape the Sealant
Use a caulking tool, putty knife, or your finger to smooth and shape the applied sealant. This helps to ensure proper coverage and adhesion. It also helps to create a neat and professional-looking finish.
- Allow for Curing
Allow the sealant to cure as per the manufacturer’s instructions. This usually involves leaving it undisturbed for a specific period until it fully sets and forms a strong bond. Avoid exposing the sealed area to moisture or stress during the curing process.
- Check for Leakage
Once the sealant has cured, inspect the sealed area for any signs of leakage or gaps. With some sealants like Adiseal, this can be done instantly without waiting for the product to cure. If necessary, apply an additional layer of sealant to reinforce the seal and prevent any potential water penetration.
- Clean Up
Clean any excess sealant or smudges with a damp cloth or mineral spirits, following the manufacturer’s instructions. It’s best to remove excess sealant before it fully cures to ensure an easier clean-up process.

Adhesive for lead flashing
As well as Adiseal being a great sealant for lead flashing, it is also a great adhesive to stick lead.
The advantage of Adiseal over other lead adhesives is it will also provide a strong waterproof seal as well as sticking the roofing felt.
Adiseal also proved to be the strongest adhesive by an independent test by Ultimate Handyman, as detailed above.
Whether Adiseal is being used at repairing a lead roof, fit lead flashing, installing lead flashing, sealant for lead flashing or used as a lead point sealant, Adiseal is the best product for the job.
How to stick lead flashing
To stick roof lead flashing make sure the surface where the adhesive will be applied is thoroughly cleaned. Use a brush to remove any loose debris. Adisolve solvent cleaner is the ideal product to clean & remove oil, grease, tar, bitumen & many other stubborn deposits. Using a fine brush like a painting brush can help remove fine dust.
Adiseal can be applied directly without the need for a blowtorch. Simply apply Adiseal adhesive & sealant to one surface & press down the lead flashing.
Adiseal can take 24 to 48 hours to fully cure but the sealing of the lead is done instantly. This allows the installer to test if the lead flashing has sealed instantly instead of testing it on another day. Pour some water over the seal to see if sealing of the lead has been done correctly.
As well as Adiseal being an adhesive for lead it will also bond other metals. Visit the dedicated page on how to bond metal for more details.
