Bond It WG4 WEATHERGUARD is a low modulus acetoxy silicone sealant that fully complies with the requirements of BS EN 15651-1,2:2012.


Bond It WG4 WEATHERGUARD is suitable for use in domestic, commercial and industrial applications. It should be used to weatherproof the perimeters of inset frames in construction applications, seal pipe and cable runs and as a lap sealant for preformed panels. It can also be used as a general construction sealant and a general purpose glass and ceramic sealant. It is ideal for use on:

  • aluminium
  • brick
  • ceramics
  • glass
  • GRP
  • primed metals and timber
  • many plastics (although adhesion levels should be tested to ensure satisfaction)


Ensure all surfaces are clean, dry and free from grease or any contaminants that may hinder adhesion. Remove any old sealant.


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. Fill the joint cavity with polyethylene foam leaving the correct joint depth (or any flexible foam if PE foam is not available). Gun the sealant firmly into the joint, leave for 1 or 2 minutes to permit the optimum tooling characteristics to develop and tool with a wetted spatula to tight finish. Tools can be cleaned in white spirit before the sealant sets. Ensure that the joint design accounts for anticipated joint movement. Once the silicone has been applied and tooled rain will not have any adverse effects on the sealant.
