Flashing Tape

Flashing Tape is a self-adhesive bituminous sealing strip which bonds instantly to provide a permanent watertight seal.

A crease resistant lead tape, this flashing tape is used for sealing and general repairs.

Flashing Tape has a heavy duty aluminium / polyester laminate facing with a high grade bitumen backing. This gives the product tear resistance, thus aiding speed and ease of application.

Flashing Tape is supplied in 10 Metre rolls in a range of different widths.

Product Uses

Flashing Tape bonds to most building materials including masonry, brick, concrete, wood, slates, metal, concrete roof tiles, glass, plastic and roofing felt.

Flashing Tape is used for the following:

  • Repairing lead flashing.

  • Sealing valley gutters.

  • Repairing leaks in guttering and drain pipes.

  • Protecting insulation for pipes and tanks.

  • Repairs to greenhouses.

  • Repairing roofing felt joints.

Application

Surface Preparation:

Surfaces must be clean and free from dust, grease, loose materials and ponding water. Gaps greater than 3mm should be filled using an appropriate filler.

For adhesion on porous or uneven surfaces, the use of a primer is advised at a rate of 1.8m² per litre and allowed to dry. Do not leave the primer for more than 24
hours and therefore only coat an area enough for covering within the day.

Some surfaces may require a second coat of primer which should be applied once the first coat is dry.

Application Method:

Cut the Flashing Tape to the length required.

To avoid any creasing remove approximately 50mm of backing paper and carefully position the sealing strip, hold the backing paper firmly and remove it steadily from the sealing strip as the product is applied.

Smooth into position using hand pressure. Using a seam roller or rounded wood smooth to ensure good contact and expel any air, especially on overlaps and at the edges.

When laying adjacent rolls Flashing Tape should be overlapped by a minimum of 25mm for a watertight seal.

The seam must be pressed firmly with a hand roller paying particular attention at the point of overlap.

In cold weather (5°C - 15°C), application will be made easier by warming the surfaces and storing the Flashing Strip in a warm place prior to use.

Do not apply in temperatures below 5°C

Limitations:

Flashing Tape will not accommodate appreciable joint movement.

Flashing Tape is not intended to withstand any form of vehicle / foot traffic.

Avoid using Flashing Tape where it will come into regular contact with solvents and oils.

Do not use Flashing Tape in conjunction with flexible PVC, vinyl or silicone sealants.

If enclosed in a cementitious mix the product may become brittle.

Any form of acidic or alkaline liquid will attack the product and should be avoided.

Soudalead® Pb - Neutral Lead Sealant

Soudalead® Pb - Neutral Lead Sealant

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.

Benefits
  • Very easy to apply

  • Colourfast and UV resistant

  • Permanent elastic after curing

  • Very good adhesion on many materials

  • Low modulus

  • Corrosion free 

Application

Typical Applications:

  • 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.

Surface Preparation:

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:

  • 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

Joint Dimensions:

  • 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.

Remarks:

  • 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.
