Question about tesa Powerbond ULTRA STRONG double-sided mounting tape

Good day.
I once experienced similar reactions. However, we then found out that the pre-treatment of the areas to be taped had not been carried out properly. For example, adhesive tape usually does not stick to dust, oil or silicone films. Skin grease must also be removed first. Most of the time, the people who mount the tape touch it at the point of adhesion and grease the adhesive surface.
Wash your hands, disinfect with alcohol, let dry clean, do not touch the adhesive surfaces and clean the surface FIRST. Helps. Guaranteed.
