Product information

tesa® Professional 4939

Double-sided removable carpet tape



Product description

tesa® Professional 4939 is a double-sided removable carpet tape that was developed specially for temporary use. It consists of a fabric substrate and a synthetic-rubber adhesive mass. The removable carpet tape forms a strong bond with carpets and rugs, but a weaker one with the surface underneath. It can be removed easily within 14 days without leaving residue. It is very easy to handle as it can be torn by hand. The universal removable carpet tape is a useful aid anywhere that (red) carpets are only needed for a short period.

  • Can be used on many surfaces (except natural and synthetic stone)
  • Ideal for fairs, exhibitions, conventions & renovations
