A three-part smart repair system consisting of water-based leather glue, tear-resistant backing fabric, and two mini brushes.

The box contains three components: a water-based leather glue in a 20-gram container, a pre-cut tear-resistant textile backing fabric, and two fine mini brushes for precise application. The glue uses a water-based polymer dispersion instead of volatile solvents. This makes it odor-neutral, non-flammable, and preserves the natural re-greasing agents in the leather collagen.\u003c\/p\u003e\n\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePermanently elastic adhesive seam instead of brittle, hard bonding.\u003c\/strong\u003e As it dries, polymer chains mechanically interlock with the open leather fibers and the backing fabric. In short: the bond remains rubber-elastic like the leather itself. This means for you: when getting into the seat bolster, the glued area stretches with it and does not tear again on the first day of stress, as happens with superglue repairs.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOdor-neutral and without pungent fumes in the interior.\u003c\/strong\u003e Classic saddler contact adhesives use volatile organic compounds, i.e., light solvents, which leave a pungent smell in the car for days. The water-based dispersion evaporates its water content and that's it. This means for you: the car is usable again after two hours, and no persistent glue smell permeates the seat upholstery and headliner.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eComplete set for an average seat bolster repair.\u003c\/strong\u003e Tear-resistant backing fabric and two mini brushes are included directly in the set — no separate accessory purchase from saddler specialists is necessary. The 20-gram tube is sufficient for three to six smart repair jobs on seat bolsters, backrest edges, or leather steering wheels, depending on the length of the crack. If you are restoring an entire seat, plan for a second set for very long crack chains.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003chr\u003e\n\n\u003cblockquote class=\"praxistipp\"\u003e\n  \u003cp\u003e\u003cstrong\u003ePractical tip from Detailing1:\u003c\/strong\u003e We see the same pattern in every second call regarding leather repair. The customer sees the crack, squeezes a thick drop of glue into it, presses it down with their hand — four weeks later, the crack is open again or a dark shadow appears on the visible side.\u003c\/p\u003e\n  \u003cp\u003eFrom our experience: the two crucial factors are degreasing and thin application. First, the adhesive edge must be stripped bare with COLOURLOCK Degreaser — otherwise, the water-based glue will bead off invisible skin fats and leather care residues. Second, the glue is sparingly applied with the mini brush between the leather fiber and backing fabric, never dropped directly into the crack from above.\u003c\/p\u003e\n  \u003cp\u003eFor thin aniline and nappa leather, additionally: rather two thin layers with a short flash-off time each than one thick one that bleeds through and leaves a shadow on the surface. This is the discipline that separates the set from a DIY attempt.\u003c\/p\u003e\n\u003c\/blockquote\u003e\n\n\u003chr\u003e\n\n\u003ch3\u003eCar Leather Glue in Four-Phase Smart Repair\u003c\/h3\u003e\n\n\u003cp\u003eThe \u003cstrong\u003ecar leather glue\u003c\/strong\u003e is not a tool for rushed actions, but the structural core of a timed four-phase workflow. If you skip a phase, you will see the result after the first week of driving.\u003c\/p\u003e\n\n\u003cp\u003ePhase one is preparation. The crack and surrounding adhesive edges are thoroughly cleaned with Leather Cleaner Mild or Strong, then degreased with COLOURLOCK Degreaser. The Degreaser is a special cleaning benzine, a volatile solvent that removes deep-seated waxes, silicones, and body fats without dissolving the leather color. Practical: without this step, the water-based glue will not find a mechanical anchor in the leather and will bead off.\u003c\/p\u003e\n\n\u003cp\u003ePhase two is inserting the backing fabric for tension cracks. Cut the supplied textile fabric two to three centimeters larger than the crack, mark the center with a pen, fix it from above with a needle, and slide it centrally under the leather with a narrow spatula. The marking serves as a check: if it is centered in the crack, the fabric lies neatly under both crack edges.\u003c\/p\u003e\n\n\u003cp\u003ePhases three and four are glue application and curing. The glue is sparingly brushed with the mini brush between the backing fabric and the back of the leather, allowed to flash off for two to five minutes, then the crack edges are pressed onto the backing fabric for 15 to 30 minutes with even pressure — clothes pegs, a sandbag, or a small steel block can help. Initial load-bearing capacity after about two hours, full final strength after 48 hours. Only then can filling with Liquid Leather or further leather care steps be carried out. Processing temperature between 15 and 25 degrees — frost destroys the emulsion, heat above 30 degrees causes the glue to set too early.\u003c\/p\u003e\n\n\u003ch3\u003eSmooth and synthetic leather yes, aluminum door panels no\u003c\/h3\u003e\n\n\u003cp\u003eThe leather glue is highly specialized. Four substrates are approved — and four areas are hard limits that even the best workflow cannot overcome.\u003c\/p\u003e\n\n\u003cp\u003eApproved are \u003cstrong\u003esmooth leather\u003c\/strong\u003e such as BMW Dakota, Mercedes Nappa, or Audi Valcona — the closed pigment layer holds the glue on the surface, which makes butt-joint processing controllable. Also approved are \u003cstrong\u003esynthetic leather and vinyl\u003c\/strong\u003e such as MB-Tex, Sensatec, or Skai, where the glue binds the torn PVC fabric to the backing material underneath. For \u003cstrong\u003eaniline leather\u003c\/strong\u003e — open-pored, undyed full leather without a lacquer layer — maximum economy is required, because the glue immediately penetrates the pores and darkens the area. For \u003cstrong\u003esuede\u003c\/strong\u003e such as Alcantara, Nubuck, or Velour, the glue is applied exclusively to the back between the fiber and the backing fabric — if it gets on the raised pile, the area clumps into a hard crust that cannot be brushed out.\u003c\/p\u003e\n\n\u003cp\u003eWhat doesn't work: hard plastics like ABS door panels, bare metal, glass, and exterior paints. The water-based dispersion finds no anchor on closed, inflexible surfaces. If an entire leather cover detaches extensively from the door panel, saddlers tend to use heat-activated contact adhesives — that's a different league and a different tool. And: with petrified leather that has been dehydrated and structurally destroyed by years of UV radiation, even this glue cannot work wonders. If the fiber breaks in your hand, a new saddler cover is the next sensible step.\u003c\/p\u003e\n\n\u003cp\u003eCompared to water-based competitor glues such as Geist. Leather Glue, the chemical basis is almost identical. The system advantage with COLOURLOCK lies in workflow integration: leather glue, Liquid Leather filler, Leather Fresh dye, and leather sealant are coordinated as a closed chain — no mix-and-match risk between brands. If you want to complement the appropriate \u003ca href=\"\/collections\/innenraum\"\u003einterior\u003c\/a\u003e workflow all around, you will find the coordinated cleaners and care products for the entire seating package in the range.\u003c\/p\u003e\n\n\u003ch3\u003eClassic car restorers, detailers, ambitious DIY repairers\u003c\/h3\u003e\n\n\u003cp\u003eThe set serves three clear target groups. If you don't fit into any of these three categories, you are better off with a complete service from a saddler or leather specialist.\u003c\/p\u003e\n\n\u003cp\u003eFirst target group: \u003cstrong\u003eclassic car and youngtimer restorers.\u003c\/strong\u003e Anyone who owns a Porsche 911 Targa, a BMW E30, or a Mercedes W107 SL with the original leather interior does not want to go to a saddler for a new cover — the original patina is irrevocably lost and the car loses visible character. Smart repair with the COLOURLOCK set is the only sensible choice here. In the relevant detailing forums, the product is the undisputed gold standard with a grade of 1.5.\u003c\/p\u003e\n\n\u003cp\u003eSecond target group: \u003cstrong\u003eused car dealers and semi-professional detailers.\u003c\/strong\u003e Torn entry bolsters on BMW M-Sport seats or Mercedes AMG seats are the typical customer fright before a test drive appointment. With the set, the damage can be repaired optically and structurally in two to three hours of work plus curing — the vehicle value increases many times over the set investment. Mini brushes and backing fabric are included directly, no additional accessory purchase is necessary.\u003c\/p\u003e\n\n\u003cp\u003eThird target group: \u003cstrong\u003eambitious convertible and leather enthusiasts with a craftsmanship claim.\u003c\/strong\u003e Those who invest the effort, disciplinedly carry out the preparation, and respect the 48 hours of final strength will end up with a repair that lasts two to three seasons. However, heavily stressed entry bolsters on the driver's seat remain inherent weak points — due to daily sliding in and turning, even a professionally glued seam may require touch-ups after twelve to 24 months. This is not a weakness of the set, but physics of shear stress. Those who prefer to tackle the damage preventively will find the suitable \u003ca href=\"\/products\/koch-chemie-leather-star-ls-lederpflege\"\u003eLeather Star leather care\u003c\/a\u003e in the range for regular re-greasing as crack prevention.\u003c\/p\u003e\n\n\u003cp\u003eThe one professional trick that is not in any manufacturer's brochure: for extremely stressed seat bolsters, we combine the gluing with the thermo-fixing method. Insert the backing fabric as usual, brush on a thin layer of glue, let it flash off — and when pressing, use a slightly warmed metal block preheated to oven-low instead of just your bare hand. The thermal shock freezes the polymer in its final form and prevents slipping under tensile load. Especially with E30 sports seats or Audi RS bolsters under constant load, this is the gesture that lasts for years instead of tearing open again after one season. This is the difference between a quick repair and a smart repair result at a saddler's level.\u003c\/p\u003e","brand":"Koch-Chemie × COLOURLOCK","offers":[{"title":"set","offer_id":57637092458831,"sku":"D1-KCX-8807-S-01","price":24.99,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/3272\/7375\/files\/8807-S-01_1.png?v=1778249510"}],"url":"https:\/\/detailing1.co\/collections\/koch-chemie-colourlock-ratgeber-leder-kleben.oembed","provider":"Detailing1","version":"1.0","type":"link"}
