- Application Instructions
Surface preparation
-
All surfaces should be clean, dry, and free from frost, grease, and loose materials.
-
When cleaning contaminated substrates, HS Butyl recommends using propan-2-ol (IPA) and allowing it to dry before applying the sealant strip.
-
When applying the tape to porous or friable surfaces, it is recommended to treat the surface with a suitable primer, such as an exterior grade PVA, to seal and stabilise the surface.
Application
-
To avoid creasing the foil, separate the foil and sealant from the backing paper as they are being unwound from the roll.
-
Once applied, use a roller to ensure good adhesion to the substrate.
-
Avoid joins in the flashing where possible.
-
Any joints should overlap by at least 120mm, with the uppermost piece overlapping the lower strip so that water drains freely over the front surface of the flashing.
-
When applying the tape to textured surfaces, such as pebble dash or rough brick, it is recommended to apply a bead of Silfix® U9 Low Modulus Silicone to the top edge of the foil to prevent water from penetrating behind the strip.
