tesa® Professional 4840

Hand tearable plastering tape for precious and smooth surfaces. Resistant to acids, bases and other chemicals.



Product description

tesa® 4840 has especially been developed to protect precious and sensitive surfaces against dirt and damage during all kinds of painting and plastering work. It consists of a stable, ribbed film backing which is coated with an uv-resistant natural rubber based adhesive. The cross-grooves allow you to tear the tape off easily and cleanly at a perfect 90° angle. This allows the plastering tape to be used quickly and precisely - at all corners and right angles. This plastering tape comprises a sturdy film backing which is coated with a light- and aging-resistant natural rubber adhesive compound.
