Elle pénètre finement dans les couches supérieures du cuir lisse pigmenté et réactive la façon dont la lumière accroche, si bien que les zones sèches ressortent moins et que les rayures paraissent optiquement refermées. Selon Koch-Chemie, la base technique est une matrice de liant souple qui s'accroche à la couche de finition PU des cuirs automobiles modernes. Le toucher naturel reste donc tout aussi souple et la surface ne s'épaissit pas. La plupart des erreurs viennent d'une couche trop épaisse — plus tu travailles fin et ciblé, plus la retouche se fond de façon invisible.\u003c\/p\u003e\n\u003ch3\u003ePréparation, réparation ponctuelle \u0026amp; la bonne application\u003c\/h3\u003e\n\u003cp\u003eAvant de commencer, tu nettoies le cuir à fond avec un nettoyant doux, pour que les huiles et la poussière ne gênent pas l'accroche.

Sur les endroits plus sollicités, un léger ponçage intermédiaire vaut le coup pour lisser la surface. Une fois sec, le cuir est utilisable tout de suite.

The set combines a slightly acidic Leather Cleaner Mild, a water-based polymer dye, and a Leather Protector into a complete three-phase workflow.

The seat is cleaned with Leather Cleaner Mild, then the dye is applied directly, and four weeks later the color peels off the bolster. The missing step is degreasing. Every smooth leather has an invisible layer of skin oils, old care lotions, and silicones that the mild cleaner does not remove. From our experience, the strict rule is: after cleaning, it is essential to degrease with COLOURLOCK Leather Cleaning Spirit. The quick check before dyeing is the tape test with painter's tape—if the tape doesn't stick, there's still grease, and you need to clean again. Only then apply the dye with a sponge, dabbing in wafer-thin layers, with a hairdryer between layers. And without exception, 24 hours must pass before the Protector is applied.\u003c\/p\u003e\n\u003c\/blockquote\u003e\n\n\u003chr\u003e\n\n\u003ch3\u003eThree phases, one sequence that is non-negotiable\u003c\/h3\u003e\n\n\u003cp\u003eThe \u003cstrong\u003eCOLOURLOCK Leather Fresh C \u0026amp; P Set\u003c\/strong\u003e is not a miracle cure for Sunday afternoon, but a continuous three-phase workflow. Anyone who skips a phase will reliably ruin the result.\u003c\/p\u003e\n\n\u003cp\u003ePhase 1 is cleaning with \u003cstrong\u003eLeather Cleaner Mild\u003c\/strong\u003e. The formulation is a mild anionic surfactant system with a slightly acidic pH, so that the fiber does not swell. Professionals always put the cleaner into a foam dispenser (Foamer Bottle), because the drier foam prevents the leather from getting soaked and becoming stiff like a board when drying.\u003c\/p\u003e\n\n\u003cp\u003ePump foam onto a slightly damp sponge, work it in with a soft leather brush in circular motions, then immediately remove it with a dry microfiber cloth. Do not let it dry, otherwise edges will form.\u003c\/p\u003e\n\n\u003cp\u003ePhase 2 is degreasing with Leather Cleaning Spirit. This component is not included in the set and must be purchased separately. Nevertheless, it is not an optional step. The cleaning spirit dissolves skin oils, sunscreen residues, and old silicone-based care lotion from the surface.\u003c\/p\u003e\n\n\u003cp\u003eThe polymer dye adheres permanently only to a degreased surface. The tape test with painter's tape is a quick quality check: if the tape sticks, the surface is grease-free and you can proceed.\u003c\/p\u003e\n\n\u003cp\u003ePhase 3 is dyeing with the \u003cstrong\u003eLeather Fresh\u003c\/strong\u003e polymer. Shake the bottle vigorously, as the water-based polymer dispersion tends to stratify. Wet the enclosed sponge, apply the material in wafer-thin layers by \u003cem\u003edabbing\u003c\/em\u003e or massaging in gentle circular movements—never spread, otherwise streaks will form.\u003c\/p\u003e\n\n\u003cp\u003eDry with a hairdryer on a medium setting between each layer. For heavily worn bolsters, three to four thin layers are realistic. Then allow to polymerize for a full 24 hours before applying the Protector. If you want to care for the cockpit and door panels in parallel, combine the set with the \u003ca href=\"\/fr\/collections\/lederpflege\"\u003eleather care\u003c\/a\u003e collection or with the \u003ca href=\"\/fr\/collections\/innenraumreiniger\"\u003einterior cleaners\u003c\/a\u003e.\u003c\/p\u003e\n\n\u003ch3\u003ePolymer film, not filler. Three hard limits\u003c\/h3\u003e\n\n\u003cp\u003eThe \u003cstrong\u003eCOLOURLOCK Leather Fresh\u003c\/strong\u003e dye is a polymer film, not a repair filler. Three substrates are taboo, three technical limits must be known.\u003c\/p\u003e\n\n\u003cp\u003eFirst limit: open-pore leather. Aniline leather, nubuck, suede, and velour leather immediately draw the water-based polymer dispersion deep into the fiber, without forming a film. The result is dark, patchy discolorations that cannot be removed without residue.\u003c\/p\u003e\n\n\u003cp\u003eBefore each application, perform the water drop test: place a drop of clear water on an inconspicuous area. If it absorbs within 30 seconds, the leather is open-pore. In that case, use COLOURLOCK Aniline \u0026amp; Suede Protector, not the C \u0026amp; P Set. Synthetic microfiber fabrics like Alcantara are also on the negative list.\u003c\/p\u003e\n\n\u003cp\u003eSecond limit: the set does not repair cracks or holes. The polymer matrix has a minimal filling effect for micro-fine surface scratches in the leather finish, but none for deep fiber damage.\u003c\/p\u003e\n\n\u003cp\u003eIf you want to close a hole in the seat bolster, you first need COLOURLOCK Fluid Leather (liquid leather) as a filler and then work with Leather Fresh for color matching. Without this preliminary work, the hole will remain visible, because the dye only forms a thin film over the wound and will tear when the seat is sat on for the first time.\u003c\/p\u003e\n\n\u003cp\u003eThird limit: no radical color changes. If you want to recolor black leather to beige, you need solvent-based spray paints with a spray gun, not the water-based C \u0026amp; P Set. The dye matches faded and worn areas to the original color—it is restoration, not redesign.\u003c\/p\u003e\n\n\u003cp\u003eOne exception is the \"Neutral\" base: 100 ml of colorless dye can be mixed with about 20 to 30 percent color pigments if you really need a special shade for a restoration project. If you want additional protection against jeans abrasion after dyeing, combine the set with microfiber cloths and brushes from our \u003ca href=\"\/fr\/collections\/zubehoer-detailing\"\u003eaccessories\u003c\/a\u003e range.\u003c\/p\u003e\n\n\u003ch3\u003eProsumers, Smart Repair specialists, and saddlers\u003c\/h3\u003e\n\n\u003cp\u003eThe \u003cstrong\u003eCOLOURLOCK Leather Fresh\u003c\/strong\u003e leather care set serves three clearly defined target groups. Anyone outside these three profiles will either overchallenge or underchallenge the set.\u003c\/p\u003e\n\n\u003cp\u003eFirst target group: Prosumers and hobby mechanics with a special restoration object. The greasy steering wheel of a youngtimer, the worn bolster in a 10-year-old BMW, the faded seat in a Mercedes E-Class Convertible. Anyone who invests a full Saturday and adheres to the three-phase logic will achieve a smart repair level without a smart repair bill.\u003c\/p\u003e\n\n\u003cp\u003eSecond target group: Smart repair specialists and semi-commercial detailing studios. They work with a spray gun or airbrush instead of a sponge, achieving a seamless factory finish without sponge texture on the leather. The OEM color database makes the set the de facto industry standard for color-accurate restoration.\u003c\/p\u003e\n\n\u003cp\u003eThird target group: Saddlers and leather restorers for larger restorations. Classic car interiors, vintage car cockpits, 80s Mercedes SL seats. In combination with Fluid Leather as a filler and, if necessary, Elephant Leather Preserver for extreme re-oiling, the set covers the complete tool chain for full restoration.\u003c\/p\u003e\n\n\u003cp\u003eCompared to the competition, the set is clearly positioned. Geist. Easy Colour Restorer is cheaper and does not require a separate topcoat due to self-crosslinking polymers, but it lacks the vehicle-specific OEM color database. GYEON Q²M Leather Set is a ceramic coating for prevention on intact new leather, not a repair system.\u003c\/p\u003e\n\n\u003cp\u003eLMX\/Coralux Keralux dominates the home furniture market with alkaline cleaners, not the automotive sector with pH-compliant formulations. If you need color restoration to original tone, the C \u0026amp; P Set is the right choice. If you want to protect new leather, a ceramic sealant is better.\u003c\/p\u003e\n\n\u003cp\u003eOne practical trick that no manufacturer brochure reveals: after the dye has dried and before the Protector, gently run the included leather sanding pad over the surface without pressure. This smooths the polymer surface, eliminates any remaining micro-roughness, and restores the fiber's original, almost factory-like feel. Only then is the Protector applied as a long-term sealant.\u003c\/p\u003e","brand":"Koch-Chemie × COLOURLOCK","offers":[{"title":"Neutral \/ set","offer_id":57637092262223,"sku":"D1-KCX-8805-S-01","price":128.99,"currency_code":"EUR","in_stock":true},{"title":"Black \/ set","offer_id":57637092294991,"sku":"D1-KCX-8805-S-01-F034","price":76.99,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/3272\/7375\/files\/8805-S-01_1.png?v=1778249509"},{"product_id":"koch-chemie-colourlock-leather-fresh-set-xs","title":"COLOURLOCK \"Leather Fresh Set XS\"","description":"\u003ch2 id=\"speakable-headline\"\u003eLeather Dye for Cars for a Steering Wheel with the COLOURLOCK Leather Fresh Set XS\u003c\/h2\u003e\n\n\u003cblockquote id=\"speakable-summary\"\u003e\n  \u003cp\u003e\u003cem\u003eWhat is the COLOURLOCK Leather Fresh Set XS?

Degreasing is done by eye, and weeks later the tint on the steering wheel peels off in thin films. The professional rule is the adhesive tape test: after cleaning with cleaning benzine or degreaser, press a short piece of painter's tape onto the spot and slowly pull it off. If the tape comes off easily, there is still skin oil or old care product on the surface, and the next tint layer would not adhere. If the tape sticks firmly, the surface is ready. No datasheet prescribes this test. From our experience, it is the insurance against the most frequent complaint in leather dyeing. With a 100 ml set, which is just enough for a steering wheel, a failed first layer is particularly expensive.\u003c\/p\u003e\n\u003c\/blockquote\u003e\n\n\u003chr\u003e\n\n\u003ch3\u003eFive-Step Workflow for Steering Wheel and Seat Bolster\u003c\/h3\u003e\n\n\u003cp\u003eLeather Fresh is step four in a fixed five-step plan.

Fill deep cracks or torn seat bolsters now with \u003ca href=\"\/fr\/products\/koch-chemie-colourlock-fluid-leather-lederfarbe-fuer-reparaturen\"\u003eFluid Leather\u003c\/a\u003e as a filler. Leather Fresh itself has no filling effect.\u003c\/p\u003e\n\n\u003cp\u003eStep 4: \u003cstrong\u003eTinting with Leather Fresh.\u003c\/strong\u003e Shake extremely well before use until pigments and binders are homogeneous. Apply the color to the enclosed sponge, never directly to the leather. Dab or apply in light circular motions in very thin layers from seam to seam, and immediately cure each layer with a household hairdryer on a medium setting from about 20 cm distance for 60 to 90 seconds. Only the heat evaporates the water and cross-links the polymer. High opacity is achieved through three to five very thin repetitions, not by a thick layer. Forcing full opacity in one go leads to blistering and the dreaded rubbing off upon the first touch. Step 5: \u003cstrong\u003eSealing.\u003c\/strong\u003e The tinted area must rest and outgas for 24 hours. Only then gently apply Leather Shield as friction protection or Leather Protector with UV protection and antioxidants, without strong pressure and without rubbing. Otherwise, fresh polymer layers will detach again.\u003c\/p\u003e\n\n\u003ch3\u003eAniline Leather, Deep Cracks, and Wrong Solvents as Hard Limits\u003c\/h3\u003e\n\n\u003cp\u003eLeather Fresh is chemically highly calibrated for semi-matte, surface-dyed smooth leather with a functioning protective layer. If the product is applied to incompatible substrates or if the wrong chemicals are used during pre-treatment, a leather interior that quickly costs four figures to re-upholster can be ruined in minutes. Three limits that must be checked before each application.\u003c\/p\u003e\n\n\u003cp\u003eFirst limit: \u003cstrong\u003eAniline leather, nubuck, and open-pore suede.\u003c\/strong\u003e These types of leather do not have a factory protective layer. The aqueous polymer dispersion penetrates uncontrollably into the open pores and coats the surface in a patchy and greasy manner. Before each application, perform the water drop test: place a drop on an inconspicuous area. If it is absorbed within 30 seconds and remains dark, the leather is open-pored, and the set is not suitable. For aniline leather, the \u003ca href=\"\/fr\/products\/koch-chemie-colourlock-aniline-nubuck-cleaner-lederreiniger\"\u003eCOLOURLOCK Aniline and Nubuck Cleaner\u003c\/a\u003e is the correct choice. However, for pigmented smooth leather with a clear protective layer or for PU synthetic leather in the interior, you are on the right track.\u003c\/p\u003e\n\n\u003cp\u003eSecond limit: \u003cstrong\u003eDeep cracks and torn seat bolsters.\u003c\/strong\u003e Leather Fresh conceals superficial scratches and colors worn areas excellently, but it does not bridge gaps. Testers in vehicle detailing forums rate exactly this point as the hardest limitation. For cracks or already torn seat bolsters, Fluid Leather as a filler is a mandatory preceding step. Third limit: \u003cstrong\u003eAggressive brake cleaners for degreasing.\u003c\/strong\u003e If, out of frugality, brake cleaner is used instead of cleaning benzine or degreaser, the factory protective layer is immediately destroyed by acetone and naphtha components, making the leather brittle. This mistake is regularly documented in DIY forums. It is irreparable.\u003c\/p\u003e\n\n\u003cp\u003eA fourth honest limitation, which marketing is reluctant to state: F034 Black usually covers in the first pass. Light shades like beige, white, or cream colors, based on experience from professional reconditioning, require five to six layers until dark scuff marks on the steering wheel are completely concealed. If you want to restore a light interior, calculate double the working time and, if in doubt, have a second XS set ready. Opened bottles can be used for six to twelve months, after which the dispersion thickens and becomes unusable for fine auto-leveling.\u003c\/p\u003e\n\n\u003ch3\u003eCar Leather Dye for Hobby Detailers and One-Time Repairs\u003c\/h3\u003e\n\n\u003cp\u003eThe XS set is the entry-level kit for exactly one application: punctual smart repair on a single vehicle. 100 ml is enough for a complete steering wheel or two heavily worn seat bolsters. Those who regularly recondition lease returns or an entire fleet should switch directly to the professional container from the \u003ca href=\"\/fr\/collections\/lederpflege\"\u003eleather care\u003c\/a\u003e collection.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eHobby detailers and car enthusiasts\u003c\/strong\u003e are the main target group. People who want to eliminate the worn greasy sheen on the steering wheel after 80,000 to 150,000 kilometers without paying for a professional re-upholstery. A steering wheel re-upholstery in the DACH region can quickly cost several hundred euros gross, while the XS set, when applied correctly, achieves a visually and haptically indistinguishable result at a fraction of the cost. For used car sellers, this is the difference between selling with or without visible wear-related depreciation.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eClassic car owners\u003c\/strong\u003e use the set to preserve the patina of 30-year-old leather and gently touch up small imperfections without destroying the historical value through complete re-upholstery. \u003cstrong\u003eFirst-time users before a larger restoration\u003c\/strong\u003e test the technique with the XS volume on a single spot before switching to the professional container. Compared to competing systems, COLOURLOCK scores at the beginner level with its user-friendly auto-leveling viscosity and OEM color database. Geist Easy Colour Restorer advertises self-cross-linking without sealing, but in the 50 ml format, it is more expensive per application and lacks the official factory color code library. Aerosol sprays like Volico or Motip work with solvent-based spray mist and require extensive masking of the interior. For the typical localized damage on the steering wheel, the sponge application of the XS set is more respiratory-friendly and more controllable in a cramped interior.\u003c\/p\u003e\n\n\u003cp\u003eFrom our experience, the crucial leverage for first-time users is not the color accuracy of the tint, but the discipline in preparation. Those who meticulously follow steps one to three will achieve a steering wheel result at a professional upholsterer's level with the XS set. Those who degrease without doing the adhesive tape test will see the tint peel off after three weeks. The tint itself is not the risk.

The core is a water-based polyurethane dispersion: colorfast pigments and abrasion-resistant binders cross-link upon drying with hot air to form a semi-gloss polymer film on the factory surface of the leather.

Degreasing is completed by eye, and weeks later, the dye on the steering wheel peels off in thin films. The professional rule is the tape test: after cleaning with cleaning benzine or degreaser, press a short piece of masking tape onto the spot and slowly pull it off. If the tape comes off easily, there is still skin oil or old care product on the surface, and the next layer of dye would not adhere. If the tape sticks firmly, the surface is ready. No data sheet prescribes this test. In our experience, it is the insurance against the most common complaint in the industry.\u003c\/p\u003e\n\u003c\/blockquote\u003e\n\n\u003chr\u003e\n\n\u003ch3\u003eFive-Step Workflow for Large-Area Restoration\u003c\/h3\u003e\n\n\u003cp\u003eLeather Fresh is step four in a fixed five-step plan. Breaking the sequence or skipping a step risks peeling within weeks. These steps have been the standard for detailing for decades.\u003c\/p\u003e\n\n\u003cp\u003eStep 1: \u003cstrong\u003eDeep Cleaning.\u003c\/strong\u003e The leather interior is cleaned with \u003ca href=\"\/fr\/products\/koch-chemie-colourlock-leather-cleaner-mild-lederreiniger\"\u003eCOLOURLOCK Leather Cleaner Mild\u003c\/a\u003e or, for heavily soiled or greasy smooth leather, with Leather Cleaner Strong. Work the foam in with a soft leather brush for 30 to 60 seconds, wipe off with a damp viscose cloth, and let dry. Never use abrasive microfiber cloths designed for paint care. They scratch the factory protective layer that the Leather Fresh must later adhere to.\u003c\/p\u003e\n\n\u003cp\u003eStep 2: \u003cstrong\u003eDegreasing.\u003c\/strong\u003e Wipe with COLOURLOCK Leather Cleaning Benzine or the solvent-free Degreaser on a lint-free cloth until the surface becomes visibly dull. Hand grease on the steering wheel, old leather care products on the seat bolsters, or surfactant residues from the cleaner will otherwise prevent adhesion. Use the tape test for verification. Step 3: \u003cstrong\u003eMechanical Smoothing.\u003c\/strong\u003e Gently level raised microfibers on worn seat bolsters with the COLOURLOCK Leather Sanding Pad, using light circular motions without pressure.

Always transfer from the 1-liter container into a smaller 100-ml dispensing bottle or a paint dish. Dabbing directly from the heavy canister with a sponge is difficult to control in a real interior and spills in two out of ten cases. Dab or apply in circular motions in very thin layers from seam to seam, immediately cross-linking each layer with a heat gun. This evaporates the water and cross-links the polymer. High opacity is achieved by repeated application, not by a thick single layer. For large areas like entire seat benches in professional operations, Leather Fresh is alternatively applied with an airbrush gun. The atomized application prevents the micro-streaks that a sponge inevitably leaves with flat application. Step 5: \u003cstrong\u003eSealing.\u003c\/strong\u003e The dyed surface must rest and outgas for 24 hours before applying Leather Shield sealant or Leather Protector without strong pressure or rubbing.\u003c\/p\u003e\n\n\u003ch3\u003eAniline Leather, Deep Cracks, and Wrong Solvents as Hard Limits\u003c\/h3\u003e\n\n\u003cp\u003eLeather Fresh is chemically highly calibrated for semi-gloss, surface-dyed smooth leather with a functional protective layer.

However, if you have pigmented smooth leather with a clear protective layer or PU artificial leather in the interior, this product is suitable. An exception: aniline leather may be dyed with Leather Fresh if the entire component is completely recolored. Local repairs will still fail.\u003c\/p\u003e\n\n\u003cp\u003eSecond limit: \u003cstrong\u003eDeep cracks and broken seat bolsters.\u003c\/strong\u003e Leather Fresh conceals superficial scratches and excellently dyes worn areas, but it does not bridge gaps. Testers in vehicle care forums rate this very point as the hardest limitation.

Third limit: \u003cstrong\u003eAggressive brake cleaner for degreasing.\u003c\/strong\u003e Anyone who uses brake cleaner instead of cleaning benzine or degreaser out of a reflex to save money will immediately destroy the factory protective layer with acetone and naphtha components, making the leather brittle and cracked. This error is regularly documented in mechanic forums. It is irreparable; the leather is scrap after this treatment.\u003c\/p\u003e\n\n\u003cp\u003eAnd the fourth honest limit, which marketing doesn't like to formulate: F034 Black covers in the first pass. Light shades like beige, white, or cream colors require five to six layers, based on practical experience from detailers, until dark scuff marks on the steering wheel or seat edges are completely concealed. If you are restoring a beige interior, double the working time per vehicle. On shiny bicast leathers that become sticky due to skin oil decomposition, Leather Fresh also does not save the structure. Here, only the color loss can be temporarily covered; the polymer film physically disintegrates.\u003c\/p\u003e\n\n\u003ch3\u003eCar Leather Dye in Professional Volume for Upholsterers and Fleet Detailers\u003c\/h3\u003e\n\n\u003cp\u003eThe Set XL is not a hobby product for Sunday repairs of a single seat bolster.

Leased vehicles returning with worn steering wheels and scuffed seat bolsters are re-dyed black with standard F034 dye in the detailing hub, because factory black is the most common OEM color in the German premium fleet.

The 46-color logic allows invisible touch-ups right on a seat surface. If the dye is precisely matched to the OEM color, a smart repair on the seat upholstery looks like factory condition. \u003cstrong\u003eFleet managers and car dealerships\u003c\/strong\u003e with standard black or carbon black leather interiors benefit from continuous inventory maintenance. A 1-liter stock is computationally more sensible than 30 to 50 individual bottles.\u003c\/p\u003e\n\n\u003cp\u003eCompared to competing systems, the Set XL is the volume-oriented answer. Geist. Easy Colour Restorer markets a 50-ml format with self-crosslinking for DIY users but cannot deliver a 1-liter professional container. Ledermax Repair #6.0, as a 2K system with a hybrid hardener, is chemically more complex and, due to its pot life of one to two hours, less flexible for quick smart repair jobs.
