It's a 1-liter container of water-based polyurethane dye in OEM Black F034 from Koch-Chemie × COLOURLOCK. The set includes: 1,000 ml of dye, cleaning and application sponges, nitrile gloves. It's enough for six to ten complete car interiors of the same color. The pH value is precisely matched to leather, the dye is water-based, and free of harsh solvents. Not for aniline leather, nubuck, Alcantara, patent leather, or open-pored suede, and does not fill deep cracks.\u003c\/em\u003e\u003c\/p\u003e\n\u003c\/blockquote\u003e\n\n\u003chr\u003e\n\n\u003cp id=\"speakable-definition\"\u003e\u003cstrong\u003eCOLOURLOCK Leather Fresh Set XL\u003c\/strong\u003e is the 1-liter professional container of \u003cstrong\u003ecar leather dye\u003c\/strong\u003e in OEM Black F034 from Koch-Chemie × COLOURLOCK, formerly from Lederzentrum Lübeck, produced at the Koch-Chemie plant in Unna since Q3 2024. It contains 1,000 ml of dye, cleaning and application sponges, and nitrile gloves. This material kit is sufficient for six to ten complete car interiors of the same color. 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. This means for you: the color isn't just a layer of paint on top; it becomes part of the leather surface.\u003c\/p\u003e\n\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOne liter of F034 Black covers six to ten complete car interiors.\u003c\/strong\u003e A standard 150-ml bottle from the Set XS is enough for exactly one vehicle. Professional detailers will use up the bulk container within two to three jobs because there are no reorders and no mixing tolerances between batches.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWater-based polyurethane dye with pH 4.5 to 5.5.\u003c\/strong\u003e The pH value precisely matches the natural acidity of the leather, at which the fiber does not swell. This means for you: the dye bonds to the surface without chemically disturbing the interior of the leather. Free of harsh solvents, no respiratory protection required, no storage in a locked cabinet, no B2B sales restrictions.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOEM color accuracy through COLOURLOCK's 46-standard color system.\u003c\/strong\u003e The factory black F034 covers the typical black tones of German premium brands without mixing. Other OEM colors can be individually mixed from the neutral base as needed, also by VIN code or submitted color sample. This means for you: seamless touch-ups in the middle of the seat surface, without a visible transition.\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 underestimated mistake in at least every third inquiry about Leather Fresh. 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=\"\/it\/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. Remove sanding dust with a cloth lightly dampened with cleaning benzine. Fill deep cracks now with \u003ca href=\"\/it\/products\/koch-chemie-colourlock-fluid-leather-lederfarbe-fuer-reparaturen\"\u003eFluid Leather\u003c\/a\u003e as a filler. Leather Fresh itself does not fill.\u003c\/p\u003e\n\n\u003cp\u003eStep 4: \u003cstrong\u003eDyeing with Leather Fresh.\u003c\/strong\u003e Shake extremely well before use to ensure pigments and binders are homogeneous. 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. Anyone who applies the product to incompatible substrates or uses the wrong chemical during pre-treatment risks ruining a leather interior that would cost five figures to replace. Three limits that must be checked before each application.\u003c\/p\u003e\n\n\u003cp\u003eFirst limit: \u003cstrong\u003eAniline leather, nubuck, and open-pored 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 unevenly and greasy. Before each application, perform the water drop test: place a drop on an inconspicuous area. If it is absorbed within 30 seconds, the leather is open-pored, and the set is taboo. 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. For cracks or already broken seat bolsters, Fluid Leather as a filler is a mandatory predecessor, supplemented in extreme cases by COLOURLOCK Neutral Binder to stabilize the fiber. 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. Anyone who wants to restore a single steering wheel or a small damaged area on a private car should more sensibly choose the 150-ml format from the \u003ca href=\"\/it\/collections\/lederpflege\"\u003eleather care\u003c\/a\u003e collection with Set XS. The large 1-liter container defines a different target group and a different scale of application.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eCommercial vehicle detailers and smart repair shops\u003c\/strong\u003e are the primary target group. 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. A 1-liter set covers six to ten of these detailing jobs. The business can work without delivery interruptions.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eSaddle makers and furniture restorers\u003c\/strong\u003e use the large container for components where a new cover would destroy the originality certificate, or for furniture upholstery with large restoration areas. 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. Swissvax Leather Healer positions itself in luxury detailing at significantly higher costs per milliliter. COLOURLOCK wins at the professional level through scalability and a complete workflow ecosystem consisting of Leather Cleaner Mild and Strong, Cleaning Benzine or Degreaser, Leather Sanding Pad, Fluid Leather, Leather Fresh, and sealing with Leather Shield or Protector. Every link in the chain is coordinated with the next. Those who also maintain the exterior during interior restoration can sensibly supplement the set with the \u003ca href=\"\/it\/collections\/innenraumreiniger\"\u003einterior cleaner\u003c\/a\u003e assortment for the cockpit, headliner, and door panels. This transforms a mere leather refresh into a complete interior refit in one working day.\u003c\/p\u003e","brand":"Koch-Chemie × COLOURLOCK","offers":[{"title":"set","offer_id":57637093310799,"sku":"D1-KCX-8818-S-01-F034","price":76.52,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/3272\/7375\/files\/koch-chemie-colourlock-leather-fresh-set-xl.png?v=1778657631","url":"https:\/\/detailing1.eu\/it\/products\/koch-chemie-colourlock-leather-fresh-set-xl","provider":"Detailing1","version":"1.0","type":"link"}
