Ampatop ProtectaStripe should be laid onto the existing support structure or shell, parallel to the eaves, with an overlap of 10 cm. It should then be nailed (with broadheaded nails) or stapled in the overlapping section, with the overlap covering the nails or staples. Tape the overlaps down with the adhesive tape Ampacoll Flexx to make them rain-proof and windproof. Rub the adhesive locations in well. Transverse joints should also overlap by 10 cm. These should be taped with Ampacoll Superfix or Ampacoll Flexx. Fix cross battens with Ampacoll ND nail seals or Ampacoll ND.Band / ND Duo nail seal tape. Connections to gutter beds and the edges of chimneys, dormer windows and other built-in fitments must be permanently glued with Ampacoll Superfix and mechanically secured. Penetration points such as ventilation shafts, ventilation flues, etc must be sealed with Ampacoll BK 535 butyl rubber tape. Porous, dusty or fleecy sub-surfaces must be pretreated with Ampacoll Primax or Ampacoll Airmax before applying Ampacoll BK butyl tapes.
