tesa® 4840

High grade plastering tape to protect smooth and delicate surfaces

Product description

tesa® 4840 consists of a stable, ribbed polyvinylchloride film backing which is coated with an UV-resistant natural rubber-based adhesive. tesa® 4840 has been specifically developed to protect precious and sensitive surfaces against dirt and damage during all kinds of painting and plastering work. The embossed tape structure allows 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 angles.

The surface protection tape also offers good paint anchorage and facilitates precise color edges during painting processes.
