bitu.grip

All surfaces to be clean, dry and sound. Surfaces to be treated should be checked by moisture meter and found to be in the ‘safe’ area before coating.

Cementitious surfaces must be primed with bitu.^®prime, which must be allowed to dry, before membranes are laid.

Stir well before use.

Practical coverage: 1,2 m²/L

Application is by stiff brush. Membranes must only be perimeter sealed over about 300 mm width and spot bonded for a first layer. Subsequent layers are fully bonded to the first layer. Membranes must be laid into still wet adhesive.

On timber roofs the first layer is laid with perimeter sealing and the rest of the area is nailed at approximately 500 mm centres using corrosion resistant clout nails. Subsequent layers are fully bonded to the first layer. Membranes must be laid into still wet adhesive. Bonded joints should be rolled immediately with a 50 kg roller to expel any entrapped air and to ensure good overall adhesion.

bitu.^®grip may be used for rejuvenating old, but still intact, roofing felts. The surface must be clean, sound and dry. Apply bitu.^®grip at approximately 1L/m² over the entire surface. Leave exposed for 4 – 6 weeks and then finish with a coat of silvakote.

Tools, brushes and mixing equipment should be cleaned immediately after use and before material has set with abe^® super brush cleaner followed by washing with soap and water.

Application temperature range: 5°C to 40°C.
