Product information "Ampacoll® INT – The translucent 2-in-1 high-performance acrylic adhesive tape"

Ampacoll® INT FlexSeal – The translucent 2-in-1 high-performance acrylic adhesive tape (airtight sealing)

Make your interior fit-out safe, efficient and airtight. Ampacoll® INT is a premium acrylic adhesive tape specially developed to meet the highest standards in modern construction. It offers an uncompromising solution for smooth surfaces in interior fit-out and combines two key applications in a single roll: it reliably seals both overlaps and joints as well as complex penetrations.


Data sheet


Benefits at a glance

  • 2-in-1 all-rounder: A single tape for the airtight sealing of building material overlaps and complex penetrations.

  • Maximum flexibility: The highly stretchable backing adapts perfectly to structural conditions.

  • Easy to use: Can be torn by hand conveniently and precisely – no tools required.

  • Visible safety: The translucent (slightly see-through) nature allows for precise, centred application.

  • Long-lasting quality: Offers exceptional resistance to ageing for over 20 years, ensuring permanently secure building envelopes.

Application tips for optimum results

Prerequisite: Ensure that the surfaces to be bonded or the substrate are completely clean, dry and free from dust and grease. If necessary, clean the areas thoroughly before application.

1. Bonding overlaps and joints Simply tear the tape by hand to the required length. Use the printed positioning line to place the adhesive tape exactly in the centre over the joint or seam. Then rub the tape down firmly to maximise adhesion to the substrate.

2. Bonding around penetrations For penetrations such as rafters, ventilation pipes or beam ends, cut the tape into small pieces, apply them in an overlapping pattern to the penetration and rub them down firmly. Important: Do not stretch the tape when applying it to penetrations! This is the only way to ensure that the stretchable backing can safely accommodate subsequent, natural movement of the building components without cracking.
