Sondorband - Sealing Material

Insulation, Building & Construction

All purpose sealing material made from flexible wax- and resin-impregnated Polyurethane foam.
Colours: Grey
Directions for Use:
  1. Dust off area of application and choose an oversize section of Sondorband according to your particular needs - see compression chart.
  2. Compress Sondorband and insert into the gap. Sondorband will expand within minutes to even out all irregularities and produce a completely effective seal.
  3. Also available with pressure-sensitive backing on one side if required. In this instance, ensure that the surface is dust free, remove the backing paper and press adhesive side of Sondorband to surface as required.

  • Sondorband is economical and easy to use.
  • Expands within minutes of insertion, evening out all irregularities.
  • Resistance to adverse weather and temperature conditions makes it an ideal sealing medium for most external applications.
  • Needs no primer and is clean to handle.
  • Suitable for sealing regular and irregular gaps against dust and draughts.
  • Used by window & door contractors and in log cabin & timber house construction.
  • Dust, dirt and waterproof sealing in motor vehicle manufacturing.
  • D.I.Y. applications.
