On washable leather in particular – think car parts, bags, seat covers or fashion pieces – the fixative stops excess pigment from bleeding out when you wash or clean. The formula comes straight from COLOURLOCK's leather know-how: it locks down dyes that have started to move, stops unwanted migration and gives you an even, settled result – a must on delicate leathers like aniline, nubuck and semi-aniline automotive hides.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eReliably stops bleeding\u003c\/strong\u003e – the fixative technology binds loose dyes so they can't lift off in the wash or transfer onto nearby materials.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWorks on any washable leather\u003c\/strong\u003e – great for cars, furniture, fashion and accessories; per Koch-Chemie it suits any leather where colour stability matters.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSettles the surface\u003c\/strong\u003e – once treated, the leather sits more colour-stable, which makes later cleaning or care steps safer and more even.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003chr\u003e\n\u003ch3\u003eFixing technology \u0026amp; how it works on bleeding leather\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eLeather Fixative\u003c\/strong\u003e uses a dedicated fixing agent that latches onto loose dyes that aren't fully bound in. That matters most on open-pore or delicate leather, where the dyes don't sit as tight as they do in modern pigmented automotive hides. The binding matrix in the fixative locks those particles down so they don't lift the moment they meet water or a cleaner. Per Koch-Chemie, the formula guards above all against the wash-out you get with leather clothing, motorcycle gear or washable interior parts. At the same time the natural feel of the leather stays put, because the fixing happens inside the top layer and leaves no visible film.\u003c\/p\u003e\n\u003ch3\u003ePrep, how to use it \u0026amp; a wash-safe workflow\u003c\/h3\u003e\n\u003cp\u003eBefore you reach for \u003cstrong\u003eLeather Fixative\u003c\/strong\u003e, the leather should be free of heavy dirt. You use the fixative either as a pre-treatment ahead of a leather wash or as a stand-alone fix. Lay it down evenly across the surface, let it sit briefly, then work it in gently so the loose dyes get bound. After that comes the wash, or a gentle next step, depending on the job. The key is not to overdose – a thin, even film is plenty. On heavily bleeding leather it's worth a quick re-check on colour stability afterwards. Once it's fixed, the material is far easier to care for and clean later without bleeding all over again.\u003c\/p\u003e\n\u003ch3\u003eResults, where to use it \u0026amp; the payoff in detail\u003c\/h3\u003e\n\u003cp\u003eAfter use the colour holds much better, especially when wet.

For car detailers, \u003cstrong\u003eLeather Fixative\u003c\/strong\u003e is ideal when colour-heavy interior parts might rub off during cleaning. In fashion it stops jackets, bags or shoes from running in the wash or in high humidity. Furniture and classic-car leather benefit too, since colour migration is a common headache there. The fixative is no substitute for a colour refresh or repair, though; all it does is lock down the pigment that's already there and stop it from moving.\u003c\/p\u003e\n\u003chr\u003e\n\u003ch2\u003eCommon questions about COLOURLOCK Leather Fixative\u003c\/h2\u003e\n\u003ch4\u003eWhich types of leather is the colour fixative suited to?\u003c\/h4\u003e\n\u003cp\u003ePretty much all of them: aniline, nubuck, pigmented leather plus washable fashion and upholstery leather.

The formula doesn't sit on top as a film — it diffuses into the leather fibres, where it brings back elasticity and natural spring. The water-repellent effect comes from the fibres taking up nourishment, which leaves them less prone to drawing in moisture by capillary action. The result: the leather stays breathable, feels natural and shows better resistance to wet conditions and light soiling. According to COLOURLOCK, the recipe is tuned so it never over-conditions the material and no blotchy patches appear when you work thin and even.\u003c\/p\u003e\n\u003ch3\u003ePrep, application \u0026amp; best practice\u003c\/h3\u003e\n\u003cp\u003eBefore you reach for \u003cstrong\u003eCare \u0026amp; Waterproofing Oil\u003c\/strong\u003e, the leather should be clean, dry and free of dust. Open-pore leathers especially benefit from a gentle pre-clean so the oil takes evenly. Lay the oil on sparingly with a soft cloth or pad and work it in with circular motions until the material starts to drink it in. Wipe off any excess after a short while so you don't get uneven patches. On very dry leather, several thin coats make sense. The leather springs back to supple straight away and takes on a naturally rich, non-glossy look. Once it's dry, the piece is good to use as normal. Repeating it now and then — how often depends on where you use it and the weather — keeps the water-repellent properties topped up.\u003c\/p\u003e\n\u003ch3\u003eResults, typical uses \u0026amp; where it isn't the answer\u003c\/h3\u003e\n\u003cp\u003eAfter treatment the leather looks evenly revived, feels softer and shrugs off moisture far better. Outdoor boots, hard-wearing bags, equestrian gear and open-pore furniture leather gain the most, since they cop constant wet-and-dry cycles.

On badly weathered leather, pairing it with intensive care, colour refresh or structural repair can be worth it.

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.

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.

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.

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=\"\/en\/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.

Without this pre-wash, coarse dirt will simply remain during the machine wash.\u003c\/p\u003e\n\n\u003cp\u003eThen comes the fixative bath in a tub: 50 ml in 5 to 10 liters of lukewarm water, 60 minutes soaking time, move briefly every 15 minutes. The moist parts are then transferred directly into the drum without rinsing, along with 80 to 125 ml of concentrate on a wool wash cycle at a maximum of 35 degrees.\u003c\/p\u003e\n\n\u003cp\u003eHigher temperatures cause the leather proteins to curdle and the material shrinks irreversibly. We regularly hear of covers that came out of the drum several clothing sizes smaller because the water was too warm or drying was done on a heater. This is not a marketing note, it's a physical limit.\u003c\/p\u003e\n\n\u003cp\u003eAfter spinning, the critical phase follows: milling. The semi-dry leather is stretched and kneaded in all directions until the fibers are flexible again. Completely dry pieces can alternatively be tumbled soft for 15 to 30 minutes in a dryer with cold air, turned inside out, never with heat. Air drying takes one to two days, lying flat on towels or hanging shape-stable at room temperature, no heater, no sun.\u003c\/p\u003e\n\n\u003cp\u003eIf you want to add aftercare to the workflow, the \u003ca href=\"\/en\/products\/koch-chemie-colourlock-care-waterproofing-oil-pflegeol-impragnierung\"\u003eCOLOURLOCK Care \u0026amp; Waterproofing Oil\u003c\/a\u003e is the right impregnation for smooth leather. Without impregnation, the fiber remains supple but loses the water repellency that protects the leather from subsequent soiling in everyday use.\u003c\/p\u003e\n\n\u003ch3\u003eStructural wash dissolves dirt, not migrated pigments\u003c\/h3\u003e\n\n\u003cp\u003eThe Leather Wash Set removes sweat, sebum, and road dust from the leather structure. Chemical pigment migrations such as denim dye transfer on light nappa are beyond its reach.\u003c\/p\u003e\n\n\u003cp\u003eStandard applications include sweaty motorcycle suits and pilot jackets, classic leather cases, removable vintage car covers, leather gloves with ingrained sweat marks, historical saddle straps, and equestrian equipment. Lambskin with firm tanning is also suitable. Forums such as autopflegeforum.eu and fahrzeugpflegeforum.de refer to the concentrate as a reference for machine leather washing. Users consistently report that the leather does not harden with correct drying.\u003c\/p\u003e\n\n\u003cp\u003eUnwashable remain open-pore aniline leathers in strong composite, very porous old leathers, exotic leather types, and furs with washable tanning. In these substrates, the water also dissolves the tanning, and the piece loses its structure. If dark pigment spots are not superficial but have migrated into the leather color, even intensive washing will not help. Then re-pigmentation with COLOURLOCK Leather Fresh is the next step.\u003c\/p\u003e\n\n\u003cp\u003eA second honest limitation: deeply ingrained mold or mildew odor in foam padding cannot be removed by washing alone, because the spores do not even reach the leather; they are under the cover. Here, the padding must be disassembled, otherwise the odor will return after three days.\u003c\/p\u003e\n\n\u003cp\u003eIf, on the other hand, only a quick wipe-down cleaning of the car interior without disassembly is required, then the \u003ca href=\"\/en\/products\/koch-chemie-colourlock-leather-cleaner-mild-lederreiniger\"\u003eCOLOURLOCK Leather Cleaner Mild\u003c\/a\u003e is the right choice, as it works on permanently installed car seats. If you need to wash dark and light leather parts separately and only need the fixative lock individually, choose the \u003ca href=\"\/en\/products\/koch-chemie-colourlock-leather-fixative-farbfixierer\"\u003eCOLOURLOCK Leather Fixative\u003c\/a\u003e in a single bottle.\u003c\/p\u003e\n\n\u003ch3\u003eFor saddlers and restorers, not for wipe-down care\u003c\/h3\u003e\n\n\u003cp\u003eThe set is aimed at users who machine wash removable leather parts and invest three hours plus drying time. For everything else, it is too elaborate.\u003c\/p\u003e\n\n\u003cp\u003eThe main target group includes saddleries, trained leather reconditioners, restorers of classic convertibles and vintage cars, and motorcycle suit cleaners. The assortment of 250 ml concentrate plus 100 ml fixative is sufficient for three to five machine washes or a larger saddler order. In regular wash-and-wax detailing on permanently installed car seats, the set plays no role. Seats cannot be put in the machine; here, the Leather Cleaner Mild is already ready in the wiping tray.\u003c\/p\u003e\n\n\u003cp\u003eHobby enthusiasts who clean a motorcycle suit once a year also benefit, provided they take the afternoon for it. Three hours of active time plus one to two days of drying is the honest effort estimate; less is not realistic.\u003c\/p\u003e\n\n\u003cp\u003eAn important consequence that reconditioners should discuss with the end customer before each job: scratches, fading, and patina concealed by dirt will become prominently visible after deep washing. A leather wash often necessitates subsequent color refreshment with Leather Fresh, otherwise the customer will be more disappointed after cleaning than before. A photo log of the prior condition, reviewed with the customer, prevents the expectation gap between \"five hours of work\" and \"looks like new.\"\u003c\/p\u003e\n\n\u003cp\u003eThe one Detailing1 insight that no marketing brochure writes: after every leather wash cycle, the machine itself must be degreased. The concentrate contains a lot of lanolin, and at 35 degrees, a sticky grease film inevitably remains in the drum and hoses. Without post-cleaning, it will ruin the next textile wash, often only two washes later, when shirts suddenly come out of the drum greasy. A blank run at 60 to 90 degrees with a strong degreasing heavy-duty detergent is sufficient.\u003c\/p\u003e\n\n\u003cp\u003eThis is the hour of effort between a satisfied saddler customer and a family with greasy shirts. Exactly where most people shorten the workflow. Whoever buys the leather detergent set buys not only the two bottles, but the commitment to consistently complete the workflow, from the fixative bath to the 35-degree limit to the subsequent machine cleaning cycle.\u003c\/p\u003e","brand":"Koch-Chemie × COLOURLOCK","offers":[{"title":"set","offer_id":57637092491599,"sku":"D1-KCX-8809-S-01","price":31.99,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/3272\/7375\/files\/8809-S-01_1.png?v=1778249510"}],"url":"https:\/\/detailing1.nl\/en\/collections\/koch-chemie-colourlock-ratgeber-nach-anwendung.oembed?page=2","provider":"Detailing1","version":"1.0","type":"link"}
