Ampatop Secura (plus)

Ampatop Secura (plus) should be laid onto the existing support structure or shell, parallel to the eaves, with an overlap  of 10cm. It should then be nailed (with broad-headed nails) or stapled in the overlapping section, with the overlap  covering the nails or staples. Tape the overlaps down with the adhesive tape Ampacoll XT 60 mm or the integrated tape to make them rain-proof and wind-proof. Rub the adhesive locations in well. Transverse joints should also overlap by 10  cm. These should be taped with Ampacoll Superfix (apply only to the fleecy reverse surface) or Ampacoll XT 60 mm.  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 (apply only to  the fleecy reverse surface) 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 Airmax before applying Ampacoll BK butyl tapes.
