Leather car interiors add a touch of luxury, but over time, cracks can appear. So, how can these cracks be treated? To answer this question, the German car magazine «Auto Zeitung» has highlighted effective and easy-to-apply solutions, the most prominent of which is leather glue, which has become an essential tool for restoring damaged pieces. As for how to apply leather glue, the magazine explains that it is sufficient to clean the damaged area well, then apply a thin layer of glue, let it air for a few minutes, and then press both sides together until they adhere firmly. However, the success of the process depends not only on the application but also on choosing the right product; leather, unlike other materials, is a flexible material that requires a highly flexible adhesive so that it does not crack later during movement or use. Despite the effectiveness of Super Glue in quickly bonding materials, using it on leather can lead to counterproductive results; this type of glue hardens quickly and forms a hard layer, which conflicts with the flexible nature of leather. To choose the best leather adhesive, the following important criteria should be considered: color matching: it is preferable that the glue color matches the leather color to avoid repair marks; solvent-free: avoid products that contain solvents or oils that could cause permanent stains or change the color of the leather; pre-testing: before full use, it is advisable to test the glue on a non-visible part of the piece to ensure its suitability. In case the tear or crack is large and cannot be glued directly, what is known as 'liquid leather' can be used. This is a flexible material used to fill the gap to give it a uniform appearance with the surrounding leather. It is important here to choose the color carefully to ensure a non-contrasting result and surface with the main color of the leather upholstery.
