Soudal | Roofing Sealant
Soudalead® Pb is a Low Modulus Neutral Cure Silicone sealant and filler for use on lead and other metals.
Soudalead® Pb is very easy to apply, maintains a permanent colour and is UV resistant.
Soudalead® Pb stays elastic after curing. It has very good adhesion on many materials and is compatible with all lead types.
Soudalead® Pb is virtually odourless and has primerless adhesion on most building surfaces.
Very easy to apply
Colourfast and UV resistant
Permanent elastic after curing
Very good adhesion on many materials
Sealing between lead and other substrates such as treated wood, metal, PVC profiles and glass.
Sealing of metal roofing sheets, building and construction joints.
Sealing joints with high movement between different building materials.
Surfaces should be clean, dry, free of dust and grease.Porous surfaces in water loaded applications should be primed with Soudal Primer 150. No primer needed for non-porous substrates.
If Soudalead® Pb comes in contact with certain surfaces such as bitumen or copper, discoloration may occur due to reaction with the substrate.
On PVC we recommend a preliminary adhesion test.
Certain paints and textured coatings on aluminium profiles can influence the adhesion.There is no adhesion on PE, PP, PTFE (Teflon®) and bituminous substrates. We recommend a preliminary compatibility test.
Application Method: With manual or pneumatic caulking gun.
Cleaning: Clean with a Surface Cleaner immediately after use.
Finishing: With a soapy solution or Soudal Finishing Solution before skinning.
Repair: With the same material
Minimum Width for Joints: 5 mm
Maximum Width for Joints: 30 mm
Minimum Depth for Joints: 5 mm
Recommendation Sealing Jobs: Joint Width = 2 x Joint Depth.
Do not use on natural stones like marble, granite etc... as it may cause staining.
Direct contact with the secondary sealing of insulating glass units (insulation) and the PVB-film of safety glass must be avoided.
A total absence of UV can cause a colour change of the sealant.
When finished with a finishing solution or soapy solution, make sure that the surfaces are not touched by this solution. This will cause the sealant not to adhere to that surface. Therefore we recommend to only dip the finishing tool in this solution.
We strongly recommend not to apply the product in full sunlight as it will dry very fast.
Do not use in applications where continuous water immersion is possible.
Do not use on polycarbonate. Use Silirub® AL2T instead.
