A high performance neutral cure silicone sealant specifically designed for use with roofing products both modern and traditional, internally and externally.

Bond It FLASH-MATE is a low modulus neutral cure fast-skinning, roof sealant. It is designed to stop weather ingression, tile lift and noise. Complies fully with the requirements of BS EN 12651-1:2012.


Bond It FLASH-MATE is is used to seal or bond dissimilar materials to prevent weather ingression. FLASH-MATE can be used to bond glass and glazing plastics as well as small sections of roofing materials under repair. Ideally suited for sealing rooflights, conservatories, soffits, glass houses, industrial roofing systems, lead flashing and to prevent tile lifting and wind noise.

FLASH-MATE is compatible with lead, galvanised steel and all metals. FLASH-MATE has excellent UV, heat and ozone resistance and sets to tough resilient rubber.

It is ideal for use on:

  • glass
  • slate
  • all metals including lead and galvanised steelconcrete and brick
  • GRP
  • sealed timber
  • plastics (including polycarbonate)
  • acrylics
  • PVCu
  • all painted surfaces


Ensure all surfaces are clean, dry and free from grease or any contaminants that may hinder adhesion. Priming may be necessary on porous surfaces.


Apply using a standard sealant gun with the nozzle cut at an angle of 45°, and to an opening slightly larger than the joint to be sealed. Best tooling is achieved if a minute or two is allowed after application before smoothing. Polyethylene foam backing rod pushed into construction joints before sealing gives a technically superior joint and minimises sealant consumption. For bonding press the two surfaces together before skinning commences. On very hot roofs skinning time will be much shorter. Once the silicone has been applied and tooled rain will not have any adverse effects on the sealant.
