An acetoxy silicone sealant which cures quickly to provide a permanent weather and waterproof seal. After application the silicone cures with atmospheric moisture to form a durable rubber seal.

  • Versatile sealant
  • High elasticity
  • Good resistance to UV, water and weather


Suitable for a wide range of building and household applications including perimeter sealing around window and door frames and sealing around worktops, tiling and sanitary fixtures.


Before applying your sealant ensure the surface is clean and dust free. Cut the cartridge seal and screw on nozzle which should be cut to required size. Gun sealant firmly into joint ensuring no air is trapped behind. If required place masking tape along joint edges, removing within 5 minutes of application. Tack free in approx 10 minutes. A joint with the correct dimensions is able to absorb movements between building materials. The joint depth should always be in the correct relationship of the joint width. A general rule is the ratio of joint depth to the width of the joint with a joint width up to 10mm is 1:1, with a minimum of 5mm in width and depth. For joints wider than 10mm, the depth is the width divided by 3 plus 6mm.
