A strong, tacky adhesive laminated with a tear, puncture and UV resistant film.
Butyl flashing tape adheres well to many substrates and offers long term durability. Ideal for flashing between conservatories, canopies and atriums; sealing around roofs and windows; repairs to roofing felts and sheets, pipes and gutters. Also suitable for resealing greenhouses and temporary remedial work such as leaking components. Unlike bitumen based products, it can be used in conjunction with plastics and PVCu.
Application temperature range: +5°C to +40°C
Shelf life: 24 months when stored flat in original packaging in cool, dry conditions.
Surface preparation: All surfaces should be clean, dry and free from frost, grease and loose materials. When cleaning contaminated substrates, Hodgson recommend that propan-2-ol (IPA) is used and allowed to dry prior to the application of the sealant strip. When applying the tape to porous or friable surfaces, it is recommended that the surface be treated with a suitable primer, such as an exterior grade PVA, to seal and stabilise the surface.
Application: To avoid creasing of the foil, separate the foil and sealant from the backing paper as they are being unwound from the roll. Once applied in place, 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, and be made with the uppermost piece overlapping on top of the lower strip, so that any water running down will drain 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 that a bead of Silfix® U9 Low Modulus Silicone is applied to the top edge of the foil to prevent water penetrating down behind the strip.
