A complete leather repair kit with mild cleaner, degreaser, flexible liquid leather for filling, opaque Leather Fresh dye, protective Leather Shield sealant, and conditioning Leather Protector. Developed for structural repair and color refreshment on pigmented smooth leather. Not suitable for aniline leather, nubuck, suede, or Alcantara.\u003c\/em\u003e\u003c\/p\u003e\n\u003c\/blockquote\u003e\n\n\u003chr\u003e\n\n\u003cp id=\"speakable-definition\"\u003eThe \u003cstrong\u003eCOLOURLOCK Complete Leather Repair Set\u003c\/strong\u003e is a complete leather repair kit from Koch-Chemie × COLOURLOCK from the Lederzentrum factory in Unna, which bundles the four phases of professional leather restoration in one box: cleaning, mechanical repair, repigmentation, and long-term protection. The core of the system is the combination of flexible liquid leather filler for tears and the water-based Leather Fresh dye, which physically anchors itself in the leather fibers when dried warm. Instead of having the entire upholstery re-covered by an upholsterer, you rebuild substance and color layer by layer.\u003c\/p\u003e\n\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eA re-upholstery by an upholsterer costs many times more than the set.\u003c\/strong\u003e The complete set addresses steering wheels, seat bolsters, gear knobs, and worn-out cover surfaces in one workflow. When preparing a used car, the investment pays for itself with the first sale, because the steering wheel in the listing image is the first impression for the buyer.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlexible liquid leather and water-based leather dye in one system.\u003c\/strong\u003e The liquid leather remains permanently elastic after curing and follows every movement of the seat bolster, instead of breaking open again at the first entry. The Leather Fresh leather dye dries to an abrasion-resistant, pigmented film that bonds with the leather pores when blow-dried warm. Result: your repair feels like original leather.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSix coordinated steps from cleaning to conditioning.\u003c\/strong\u003e Cleaner Mild gently opens the pores, the degreaser frees the surface from skin oils, the liquid leather fills tears flush, the Leather Fresh leather dye applies the tint in thin layers, the Leather Shield sealant repels jean dye transfer and friction, and the Leather Protector with medical care oil conditions older leather against drying out.\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 From our experience, we see the same mistake again and again — the fresh tint peels off after a few weeks because the degreasing step was skipped or performed too briefly. The simple rule: after Cleaner Mild, always follow up with the degreaser and rub the top coat until the surface appears visibly dull and is slightly sticky to the touch. Only this dissolution ensures that the new paint layer adheres. Otherwise, skin oils or residues of old leather care act like a release film and block the bonding — even on a visually clean steering wheel. Those who save time here will pay for it twice when reworking.\u003c\/p\u003e\n\u003c\/blockquote\u003e\n\n\u003chr\u003e\n\n\u003ch3\u003eFrom Tears to a Controlled Restored Seat in Six Steps\u003c\/h3\u003e\n\n\u003cp\u003eRestoration with the set follows a fixed six-step process that is non-negotiable in this order. Skipping a step risks a peeling tint, chipped areas, or a cloudy finish.\u003c\/p\u003e\n\n\u003cp\u003eStep 1: \u003cstrong\u003eFoam cleaning with Cleaner Mild.\u003c\/strong\u003e Fill the foam dispenser, apply foam with a leather brush or sponge, and work in seam-to-seam movements for 30 to 60 seconds. Remove with a damp viscose cloth. Never use abrasive microfiber cloths from paint preparation — they scratch the protective top coat layer of the leather.\u003c\/p\u003e\n\n\u003cp\u003eStep 2: \u003cstrong\u003eMechanical preparation and degreasing.\u003c\/strong\u003e Rub the dissolving degreaser on a lint-free cloth until the surface becomes dull and sticky to the touch. For heavily used steering wheels with ingrained hand grease residues, this can take five to ten minutes. Never use brake cleaner as a cheap alternative — it leaches the natural leather material and makes it brittle. Gently break rough edges or protruding fibers with the enclosed sanding pad, vacuum up sanding dust.\u003c\/p\u003e\n\n\u003cp\u003eStep 3: \u003cstrong\u003eStructural repair with liquid leather.\u003c\/strong\u003e Deeper tears and cracks are filled flush with the tinted filler. For through holes, reinforce the supplied repair fabric with leather glue to create a load-bearing base. Allow to dry completely.\u003c\/p\u003e\n\n\u003cp\u003eStep 4: \u003cstrong\u003eTinting with Leather Fresh leather dye.\u003c\/strong\u003e Shake the bottle vigorously, apply the dye to the applicator sponge, and apply in dabbing motions — never brush. Brushing immediately creates visible streaks because the water-based paint dries within seconds. After each thin layer, dry with a hot air dryer on a moderate setting until the water has evaporated. Two to four thin layers are sufficient for full coverage.\u003c\/p\u003e\n\n\u003cp\u003eStep 5: \u003cstrong\u003eSealing with Leather Shield.\u003c\/strong\u003e After at least 24 hours of curing time, ideally the next day. Apply friction-free and sparingly with a soft cloth — the sealant lays down a protective sacrificial layer that absorbs jean dye transfer and daily friction before it reaches the fresh tint.\u003c\/p\u003e\n\n\u003cp\u003eStep 6: \u003cstrong\u003eConditioning with Leather Protector.\u003c\/strong\u003e For older leather and convertible seats, work in the care product with medical care oil — it penetrates the fibers, slows down drying out, and protects against fading of the fresh pigments with built-in UV filters and antioxidants. The professional recommendation from the \u003ca href=\"\/fr\/collections\/lederpflege\"\u003eleather care range\u003c\/a\u003e: rather one thin layer more than one thick one.\u003c\/p\u003e\n\n\u003ch3\u003eAniline, Alcantara, and Bycast are Excluded\u003c\/h3\u003e\n\n\u003cp\u003eThe set is chemically precisely calibrated for pigmented smooth leather with a clear top coat layer. Applying it to incompatible material can ruin a seat cushion in one minute, which costs a lot of money to re-cover. Four strict limits to check before any repair.\u003c\/p\u003e\n\n\u003cp\u003eFirst limit: \u003cstrong\u003eAniline leather, semi-aniline, nubuck, and open-pored suede.\u003c\/strong\u003e These types of leather do not have a factory top coat — the open pores absorb cleaner and leather dye like a sponge, stick together, and become irreversibly stained. If pigmented smooth leather with a closed surface → Complete Leather Repair Set. If open-pored aniline or nubuck leather → \u003ca href=\"\/fr\/products\/koch-chemie-colourlock-aniline-nubuck-cleaner-lederreiniger\"\u003eCOLOURLOCK Aniline \u0026amp; Nubuck Cleaner\u003c\/a\u003e as a specialized alternative from the same manufacturer line.\u003c\/p\u003e\n\n\u003cp\u003eSecond limit: \u003cstrong\u003eAlcantara and microfiber fabrics.\u003c\/strong\u003e The binders in the leather dye and the synthetic fats in the Leather Protector permanently bond the fine fiber tips. Alcantara loses its typical suede feel and becomes dull. Third limit: \u003cstrong\u003eplastic-coated split leather.\u003c\/strong\u003e On these synthetic coatings, the leather fat is not absorbed and remains as a sticky film on the surface. Fourth limit: \u003cstrong\u003eworn-out material without a load-bearing fiber structure.\u003c\/strong\u003e In the case of deeply torn seat bolsters without a stable inner core, a combination of liquid leather and tint will sooner or later break open again — then the only way is to an upholsterer.\u003c\/p\u003e\n\n\u003cp\u003eIn the GTÜ test, the Smooth Leather Care Set Mild received a rating of 1.8 and was the only one of the twelve tested products to achieve the maximum score in the application category. For frequent driver steering wheels or sports seat bolsters, the tint will still wear off again after 12 to 24 months — this is a physical limitation of a water-based paint without additional hardener, not an application error. An honest ordering hurdle: if the remaining leather is heavily faded by UV, the factory color code no longer exactly matches the actual seat color — then sending a physical leather sample is mandatory for a color-identical mix.\u003c\/p\u003e\n\n\u003ch3\u003eFor Detailers, Upholsterers, and Ambitious Restoration Professionals\u003c\/h3\u003e\n\n\u003cp\u003eThe Repair Set is intended for workshops, used car detailers, upholsterer toolboxes, and ambitious classic and youngtimer owners who want to repeat repair and tinting in a calculable workflow. For the selective weekend care of new leather, it is oversized.\u003c\/p\u003e\n\n\u003cp\u003eDetailing businesses calculate economically: a worn steering wheel noticeably lowers the perceived value of a vehicle in an advertisement. The smart repair treatment with the set takes 60 to 90 minutes of active time plus drying breaks. Classic and youngtimer owners appreciate the Leather Protector with medical care oil for patina preservation — it is acid-free and is also used in museum conservation.\u003c\/p\u003e\n\n\u003cp\u003eHowever, if only color refreshment without structural repair is needed, the \u003ca href=\"\/fr\/products\/koch-chemie-colourlock-complete-colour-set\"\u003eCOLOURLOCK Complete Colour Set\u003c\/a\u003e is more cost-effective per vehicle, because liquid leather is not included but complementary sealants are. The simple if-then logic: Repair Set for combined structural damage plus tinting, Color Set for pure color smart repairs on multiple seats.\u003c\/p\u003e\n\n\u003cp\u003eA second truth that professional detailers know: successful restoration is 80 percent preparation and 20 percent tinting. Those who thoroughly complete the degreasing phase and build up the tint in thin layers with blow-drying achieve a result that is convincing even in daylight. Those who are sloppy or apply too thickly will see streaks at the first ray of sunshine and will have to rework for the next few hours.\u003c\/p\u003e\n\n\u003cp\u003eThe insider trick from detailing practice, which the official instructions do not formulate so clearly: liquid leather can hardly be sanded without flattening the leather pores. Professionals use a solvent-based GLD pen instead of sanding grit — it minimally re-dissolves the surface of the dried liquid leather and creates invisible transitions to the old leather. For heavily structured areas, fine sandpaper with a grit of 1000 additionally replaces the rigid sanding pad to preserve the original grain. Combined with blow-drying between each individual tinting layer, this is the difference between a six-month restoration and one that lasts two years on the entry bolster.\u003c\/p\u003e","brand":"Koch-Chemie × COLOURLOCK","offers":[{"title":"set","offer_id":57637092753743,"sku":"D1-KCX-8814-S-01-F034","price":317.48,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/3272\/7375\/files\/koch-chemie-colourlock-complete-leather-repair-set.png?v=1778657623","url":"https:\/\/detailing1depot.com\/fr\/products\/koch-chemie-colourlock-complete-leather-repair-set","provider":"Detailing1","version":"1.0","type":"link"}
