BBA 10/4787 (PS1) BBA 10/4787 (PS1)
Bituminous SBS modified membrane reinforced with a non-woven polyester felt. Combined underlay and venting membrane for partial-bond applications finished with easy peel polyethylene film finish.

Instruction for Use

1. Substrate should be dry and clean from grease, dirt, debris or any other contaminants.

2. Where applicable, prime surface with CURIDAN, BITUMEN PRIMER+ or BITUMEN PRIMER HM in accordance with DANOSA instructions and allow to dry.

3. For field applications:

A. Roll the membrane into position, allowing for 80mm side overlaps and100mm head overlaps and cut to length. All overlaps and cross joints should be staggered by a minimum of 300mm.

B. Cut across the removeable protective film underside and peel the film off.

C. Peel the leading edge of the film up and tuck it under the roll to enable the release of the remainder when unrolling.

D. Roll the membrane forward, applying even pressure downwards and outwards, avoiding trapping pockets of air.

E. Roll back the remaining portion of the membrane to the leading edge of the release film.

F. On completion, use a soft broom or roller to apply pressure over the total area, ensuring all overlaps are fully sealed.

4. For detail applications

A. Place the membrane into position, allowing for 80mm side overlaps and100mm head overlaps and cut to length ensuring all overlaps and cross joints are staggered by a minimum of 300mm.

B. Remove protective film from rear of the membrane.

C. Apply pressure and consolidate the bond to the substrate, ensuring all overlaps are fully sealed.

Where falls apply, membrane rolls should be rolled up the slope so that water drains over and not into membrane overlaps
