  • Patent number: 10890202
    Abstract: A method for attaching a fastening element to a surface includes arranging a basic body in contact with the surface using an adhesive ring. The surface, the adhesive ring, and a gap therebetween form airtight barriers of a space. The basic body has at least one air- and/or water-permeable connection between the space and an outer side of the basic body. An adhesive is introduced into the space so that it is filled with a quantity of adhesive which has a contact surface with the basic body. A curing process for the adhesive provides moisture, wherein prior to the curing process or/and during the curing process, the adhesive ring and the quantity of adhesive are heated so that some of the adhesive located in the region of the contact surface forms an insulating layer which is cured over and beyond the contact surface and constitutes a further airtight barrier for the remaining quantity of adhesive which has not cured.
