You can buy tesafix 4939 tesa double-sided tape in our shop at a low price with fast delivery! It is one of the robust, high-quality adhesive tapes – a product from the manufacturer tesa.
The tape is a universal adhesive tape: whether as a laying tape for carpets and other floor coverings or as an assembly tape for walls – the tesa double-sided adhesive tape tesafix 4939 can be attached to almost all surfaces, whether smooth or rough, porous or textured.
The tesa double-sided adhesive tape 4939 has a carrier made of fine-mesh , highly conformable fabric coated with adhesive on both sides . The adhesive, a synthetic rubber, sticks on both sides with two different adhesive strengths: the side that is stuck to the surface has a weaker adhesive strength and can be removed almost without residue for up to 14 days. Where materials can be fixed to the tape, i.e. on the surface covered by paper, the adhesive offers a stronger adhesive strength. You can order tesafix 4939 in our shop in two widths: 25 m x 38 mm and 25 m x 50 mm (length x width).
As an alternative to this product, we recommend a wide selection of other double-sided adhesive tapes, specifically the GT 702 – a residue-free removable double-sided adhesive tape with two sides of different adhesive strengths. Or the GT 703 – the more affordable double-sided cloth tape, equally strong and with a weaker adhesive.

tesa double-sided tape tesafix 4939 – strong on carpet, weaker on the surface
t esa tesafix 4939 is a double-sided tape of good brand quality. The universal tape, coated on both sides with different adhesive strengths, allows a variety of applications: Whether for temporarily laying carpets or other floor coverings, for crafting and fixing decorative material or for hanging signs, posters, etc. – a fine-mesh fabric is one of the particularly adaptable carriers that can hold onto almost any surface and still have good recovery.
You can buy the tesa double-sided tape here as a roll in two widths: 25 m x 38 mm and 25 m x 50 mm (length x width), it offers high initial adhesion (tack ) and sticks to the side facing the substrate with a weaker adhesive force of 5 N/cm. On the closed side, covered by a paper, the adhesive mass has a higher adhesive strength of 7 N/ cm (eachon steel).
tesafix 4939 assembly tapes are easy to use and, thanks to their fabric, they are adaptable and stretchable up to 40%. The tapes have good chemical resistance and moisture resistance . Like most other double-sided tapes, tesafix 4939 has only limited resistance to aging.
Choose tesa double-sided tape for indoor use, for example for laying carpets temporarily at trade fairs, events, etc. These adhesive tapes are not designed for outdoor use and can only be used for short periods under protected conditions .
The tesa double-sided tape 4939 can be removed without residue from most surfaces under normal conditions for up to 14 days. Please test sensitive surfaces (painted surfaces, wood, natural and artificial stone) before individual use.
Practical and universally applicable: adhesive mass with different adhesive strengths
The tesa double-sided tape 4939 has the same adhesive mass (synthetic rubber) but with two sides that have different adhesive strengths. This offers the advantage when used as a temporary laying tape or assembly tape that the side that sticks less to the substrate is easier to remove after use.
- Top: The covered side, which is protected by a release paper, has a high initial tack of 7.5 N/cm and is used to securely fasten carpets or other materials that are difficult to bond.
- Backing: The open side that adheres to the substrate has a weaker initial adhesion of 5 N/cm. This backing offers good repositionability on most surfaces, and the tape can be removed without leaving residue for up to 14 days .
Adhesive force of assembly adhesive-tape/masking tape in detail
The popular mounting and installation tapes from tesa are equipped with detailed information about their adhesive strength in the technical product information provided by the manufacturer. This is because an adhesive mass does not adhere equally to every surface. There are easy-to-bond surfaces, as well as surfaces (often plastic) on which it is possible that one and the same adhesive will adhere less well .
Side facing up:
- adhesion to steel: 7.5 N/cm (initial), 8 N/cm after 14 days
- Adhesive strength on PE: 4.5 N/cm (initial), after 14 days 5 N/cm
- Adhesive strength on PP: 6.5 N/cm (initial), after 14 days 5 N/cm
Open side (back, down):
- adhesive strength on steel: 5 N/cm (initial), after 14 days 5.5 N/cm
- Adhesive strength on PE: 2.5 N/cm (initial), after 14 days 3 N/cm
- Adhesive strength on PP: 4.5 N/cm (initial), after 14 days 2.5 N/cm
color="green]A fabric carrier helps to fix the tape to rough and porous surfaces:. For surfaces that are difficult to bond, the double-sided cloth tapes help to adapt to the surface more evenly in order to develop a higher level of adhesion. If, on the other hand, you want to attach the double-sided adhesive tape to smooth surfaces, such as PVC flooring, you should choose a double-sided film adhesive tape, such as GT 704 or GT 702. This is because foils adhere better to smooth surfaces and can usually be removed more easily and usually even in one piece from the surface.
