tesa® Professional 4439

Waterproof masking tape for precise and flat paint edges outdoors

Product description

The tesa Precision Mask® Outdoor guarantees razor-sharp paint edges for the outdoors. Because the adhesive compound and backing material are not only extremely precise, they are also particularly weatherproof and UV-resistant. This waterproof masking tape comprises a tear-proof, thin special backing which is coated with an acrylate adhesive compound. Thanks to this combination, the waterproof masking tape remains stable for a long time in all weathers. The paper masking tape is a reliable partner for painting work of all kinds and, combined with sound workmanship, will return excellent results.

Main features

  • Outdoor applications
  • For long-term applications (up to 8 weeks)
  • Flat, sharp edges to paint and lacquer
  • For high-quality painting and lacquering work

1 The application of an adhesive tape on weathered surfaces may lead to residues during the de-masking. Thus before using an adhesive tape on a weathered surface we recommend to make a trial application for up to 24 hours.
