tesafix 4939 Carpet Installation Tape, 25 m x 50 mm, white-translucent

The double-sided tesafix® 4939 installation tape provides a strong, temporary hold for carpets while allowing for easy removal with virtually no residue.

Description

tesafix® 4939 is a high-quality double-sided installation tape featuring a strong PET fabric backing and a high-performance synthetic rubber adhesive with differentiated adhesion strengths—strong on the carpet, weaker on the substrate. The specially developed adhesive on the open side offers very high initial tack and, at the same time, allows for nearly residue-free removal for up to 14 days on almost all substrates, except natural and artificial stone (in which case an individual test is absolutely necessary before use). Thanks to its good resistance to moisture and chemicals, its excellent tack, and its short-term temperature resistance up to 80 °C, tesafix® 4939 is ideal for temporary installations at trade shows, exhibitions, conventions, and during renovation work.
