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.

HS Butyl Foilband 0316 is normally supplied as a preformed strip on a siliconised release paper. A wide range of dimensions can be supplied. Product dimensions will determine the number of rolls per carton.
