This is necessary

At the junction of the paintings, you need to stick a tape from such a material that can compress and stretch, like a film. This is necessary in order to avoid the appearance of folds or peeling of the tape or film in the future. Since such troubles are most often found in places where pipes pass, then you need to use double -sided adhesive tapes, which are made of butyl, and the places where the joint must be pressed with strips.
