Ampatex Cento is both a vapour check and an air seal. All joints, gaps, overlaps, connections and openings must be hermetically sealed. Surface damage must be sealed. In dry interiors, Ampatex Cento should be used on the warm side of the heat-insulating layer, and in areas where there is an overlap it should be fastened with concealed staples or nails. The smooth, printed side faces into the room and this is the surface onto which the next product should be taped. When laying, make sure that the strips overlap by 10 cm. The overlaps should then be completely covered with the Ampacoll INT supplied. Ampacoll DT adhesive tape is useful where the underlying material cannot be nailed. Finally the lining on the inside is fixed in place. Ampacoll BK 530 or Ampacoll RA are used for edge connections. Porous or dusty surfaces should be pretreated with Ampacoll Primax. Penetrations such as ventilation pipes, conduits, purlins, rafters, etc. should be permanently sealed with Ampacoll BK 535, 50 mm wide. With porous, dusty or rough surfaces, a pretreatment of Ampacoll Primax is also required.
