Abstract:
A process for fixing an article to a substrate with a mounting set including two receptacles storing an aerobic adhesive and a hydrophilic substance, respectively. The aerobic adhesive and the hydrophilic substance are removed from the two receptacles and then mixed together to prepare the fastening. A layer of the fastening composition is applied to the article. The article is fixed to the substrate by pressing the layer of the fastening composition against the substrate. The aerobic adhesive in the layer hardens because of the moisture contained in the hydrophilic substance.
