It acts before damage occurs: a wafer-thin sacrificial layer on pigmented new leather, a matched formula for faux leather and vinyl, a deeply penetrating oil for open-pored smooth leather, and a fluorocarbon-free sealant for fabric, Alcantara, and convertible tops. The surface is protected; conditioning happens elsewhere.\u003c\/p\u003e\n\n\u003cul\u003e\n\n  \u003cli\u003e\n\n\u003cstrong\u003eThe sacrificial layer takes the abrasion, not your leather.\u003c\/strong\u003e Modern OEM leathers are intentionally finished with a rough texture so they look matte—it is precisely this structure that acts like fine sandpaper on clothing fabric when getting in and out, and vice versa. The polymer layer of COLOURLOCK \"Leather Shield\" wears off at this point, not the leather finish. That is why you want to renew it on the driver's seat every three to six months.\u003c\/li\u003e\n\n  \u003cli\u003e\n\n\u003cstrong\u003eJeans dye stays on top instead of soaking in.\u003c\/strong\u003e The blue cast on light-colored leather is not dirt, but dye that migrates into the microporous finish. On a sealed surface, it lands on the protective layer and comes off during the next normal cleaning. Without a protective layer, it sooner or later becomes a case for the repair line.\u003c\/li\u003e\n\n  \u003cli\u003e\n\n\u003cstrong\u003eFluorocarbon-free, and it stays that way.\u003c\/strong\u003e The textile sealant, Allround Textile Sealant \"St0.01\", is water-based and contains no fluorocarbon resins. It wraps around individual fibers in three dimensions instead of clogging the spaces between the weave—the upholstery remains breathable. To be honest: Fluorinated products make oil bead up a bit more strongly. But in return, this formula won't be pulled from the market with the next PFAS regulation update.\u003c\/li\u003e\n\n\n\u003c\/ul\u003e\n\n\u003chr\u003e\n\n\u003cblockquote class=\"praxistipp\"\u003e\n\n  \u003cp\u003e\u003cstrong\u003ePro-tip from Detailing1:\u003c\/strong\u003e If a sealant disappoints, it is rarely the product's fault and almost always the step before it. Skin oils, sunscreen, and residue from care products lie on the leather as an invisible film, and the sealant encapsulates this film—the result is exactly the greasy shine you wanted to prevent. Therefore, first clean with a leather cleaner, remove surfactant residue with a slightly damp cloth, and degrease the contact surfaces separately. Then work sparingly: a wafer-thin, even film; lint-free cloth; do not massage in; do not buff out. Anyone who saturates the surface will get white edges and sticky islands instead of protection when it dries.\u003c\/p\u003e\n\n\n\u003c\/blockquote\u003e\n\n\u003chr\u003e\n\n\u003ch3\u003eCOLOURLOCK protects leather because COLOURLOCK repairs leather\u003c\/h3\u003e\n\u003cp\u003eThose who repair leather professionally know best which damage can be prevented. That is exactly where this product line comes from.\u003c\/p\u003e\n\n\u003cp\u003eCOLOURLOCK was founded in 1995 as a leather center in Rosdorf near Göttingen and from the beginning supplied saddlers, furniture workshops, and vehicle detailers—the very people who recolor worn side bolsters and rescue faded steering wheel rims. Since October 2023, the specialist has been part of Koch-Chemie in Unna; therefore, the line is branded Koch-Chemie × COLOURLOCK in our shop. The mindset has not changed.\u003c\/p\u003e\n\n\u003cp\u003eThis background explains why the protective products look different from the rest of the market. They don't promise shine or a water-beading film for show, but rather the preservation of the condition the material was in from the factory. For pigmented automotive leather, this means: silk-matte remains silk-matte, the feel remains the same, nothing feels smoother or more rubbery afterwards than before.\u003c\/p\u003e\n\n\u003cp\u003eThe second difference is the order of operations in your head. In professional detailing, protection is not the finishing touch after a wash, but a separate work step with its own preparation. Clean, degrease, repair or dye if necessary, then protect. Anyone who shortcuts this chain doesn't get half an effect, but none at all—and usually an optical problem on top of it.\u003c\/p\u003e\n\n\u003cp\u003eAnd a third point that separates the brand from pure car care manufacturers: The focus extends beyond the car. Furniture, handbags, equestrian sports, outdoor shoes—the same formulas have been used for decades on leathers that become significantly older than any leasing vehicle. The substrate knowledge behind it is broader than a category for vehicle interiors might suggest.\u003c\/p\u003e\n\n\u003ch3\u003eEvery material gets its own protection principle\u003c\/h3\u003e\n\u003cp\u003eThere is no single interior sealant for everything. There is genuine leather, faux leather, open-pored natural leather, and textile—and each of them reacts to a different physical principle.\u003c\/p\u003e\n\n\u003cp\u003eFor pigmented smooth leather—the standard in cars—there is the \u003ca href=\"\/en\/collections\/koch-chemie-colourlock-versiegelung-echtleder\"\u003eGenuine Leather Sealant\u003c\/a\u003e with COLOURLOCK \"Leather Shield.\" An aqueous polymer dispersion crosslinks as it flashes off to form a flexible, transparent network that lowers the surface's coefficient of friction and closes the capillaries of the top finish. Important here: The film remains permeable to water vapor. A truly airtight sealant would trap heat and moisture, causing the leather to age faster.\u003c\/p\u003e\n\n\u003cp\u003eFaux leather, vinyl, and PU-coated split leather require different chemistry. The \u003ca href=\"\/en\/collections\/koch-chemie-colourlock-versiegelung-kunstleder\"\u003eFaux Leather Sealant\u003c\/a\u003e with COLOURLOCK \"Artificial Leather Protector\" works with modified polyurethane polymers, because a synthetic matrix has no pores and therefore does not accept rehydration. The real task is different: slowing the migration of plasticizers from the material and lowering friction without anything floating on the closed surface and becoming sticky.\u003c\/p\u003e\n\n\u003cp\u003eBoth protective products for seat leather are bundled under \u003ca href=\"\/en\/collections\/koch-chemie-colourlock-versiegelung-lederversiegelung\"\u003eLeather Sealant from COLOURLOCK\u003c\/a\u003e if you want to compare genuine and faux leather side by side—in modern interiors, they are often found in the same seat anyway.\u003c\/p\u003e\n\n\u003cp\u003eOpen-pored and natural smooth leathers cannot tolerate a film at all. On them, a polymer layer hardens unevenly and clogs the pores. For this, there is the \u003ca href=\"\/en\/collections\/koch-chemie-colourlock-versiegelung-lederoel\"\u003eLeather Oil \u0026amp; Waterproofing\u003c\/a\u003e with COLOURLOCK \"Care \u0026amp; Waterproofing Oil\": an oil-fat combination that diffuses into the fiber structure and makes the capillaries hydrophobic from the inside. Water beads up because the leather is saturated—not because there is a layer over it.\u003c\/p\u003e\n\n\u003cp\u003eAnd everything textile—fabric upholstery, carpet, trunk, Alcantara, fabric top—gets the \u003ca href=\"\/en\/collections\/koch-chemie-colourlock-versiegelung-textilversiegelung\"\u003eTextile Sealant\u003c\/a\u003e with the Allround Textile Sealant \"St0.01.\" It lowers the free surface energy of the fiber so much that the contact angle of a drop rises significantly above 90 degrees and liquid rolls off instead of soaking in. Incidentally, it is the first COLOURLOCK product to carry the alphanumeric Koch-Chemie nomenclature and was developed in Unna—the synergy product of the acquisition.\u003c\/p\u003e\n\n\u003ch3\u003eSealants protect the surface, conditioners work inside\u003c\/h3\u003e\n\u003cp\u003eWe intentionally treat protection and conditioning as two separate categories. The reason is not catalog logic, but physics.\u003c\/p\u003e\n\n\u003cp\u003eConditioning products soak into the leather's capillaries and work there: replenishing oils, softening, and providing UV absorbers to prevent fading. Sealants do the opposite—they remain on top and absorb mechanical stress. One keeps the fiber supple; the other keeps the surface intact. A product cannot do both simultaneously because it must either penetrate or form a layer.\u003c\/p\u003e\n\n\u003cp\u003eThis leads to a practical rule that surprises many: For young, pigmented leather in the first few years, protection is the right answer, not conditioning. The finish is still intact, the fiber is still saturated—what is missing is abrasion protection. Only when leather becomes older, drier, and more porous does the ratio shift, and \u003ca href=\"\/en\/collections\/koch-chemie-colourlock-pflege\"\u003econditioning from COLOURLOCK\u003c\/a\u003e takes the lead role. By the way, the same applies consistently to the UV aspect: COLOURLOCK \"Leather Shield\" does not provide UV protection; the conditioning milk does that.\u003c\/p\u003e\n\n\u003cp\u003eWhere the order is reversed, we regularly see the result in inquiries: conditioning milk applied thickly to modern, sealed seat leather. It cannot soak in—neither through the pigment layer nor the protective layer—and remains as a sticky film that immediately attracts dust, dog hair, and lint. The seats then don't feel conditioned, but sticky. If you want to do both, the rule is: clean, seal, let it flash off, and only apply conditioner where the leather actually absorbs it.\u003c\/p\u003e\n\n\u003cp\u003eWith faux leather, the separation is even sharper. There is simply nothing to nourish there. Anyone who \"conditions\" faux leather is applying grease to a synthetic surface that will never absorb it—protection is the only sensible measure here.\u003c\/p\u003e\n\n\u003ch3\u003eWithout cleaning and degreasing, no sealant will hold\u003c\/h3\u003e\n\u003cp\u003ePreparation determines the result, and more significantly than the choice of product.\u003c\/p\u003e\n\n\u003cp\u003eOn leather, this means: first work with a suitable cleaner from the \u003ca href=\"\/en\/collections\/koch-chemie-colourlock-reinigung\"\u003ecleaning range of COLOURLOCK\u003c\/a\u003e, give the foam about 45 seconds to work instead of scrubbing with pressure, and only use soft brushes. Hard household brushes flatten the fine grain of the finish—the leather will shine greasy permanently afterwards, and no sealant will reverse that.\u003c\/p\u003e\n\n\u003cp\u003eThen remove the surfactant residue with a slightly damp cloth and treat the contact surfaces with the \u003ca href=\"\/en\/collections\/koch-chemie-colourlock-reinigung-entfetter\"\u003eDegreaser from COLOURLOCK\u003c\/a\u003e. Only on a degreased surface will the polymer bond with the leather surface instead of the skin oils on top of it.\u003c\/p\u003e\n\n\u003cp\u003eThe application itself is unspectacular and should stay that way: wafer-thin with an applicator or lint-free cloth, in overlapping passes from seam to seam, working quickly. Do not massage in, do not buff out—friction while still damp destroys the even film formation. At normal room temperature, the surface flashes off in a few minutes. On the driver's seat, refreshing every three to six months is worth it; on back seats and door panels, six to twelve months is enough.\u003c\/p\u003e\n\n\u003cp\u003eTextile has its own ground rules. The fabric must be clean to the fiber, surfactant-free, and completely dry—the \u003ca href=\"\/en\/collections\/koch-chemie-colourlock-reinigung-polsterreiniger\"\u003eUpholstery, Textile \u0026amp; Alcantara Cleaner\u003c\/a\u003e is the right preparer for this. The sealant is sprayed on or worked in with a microfiber sponge in a cross-hatch pattern, and then it needs rest: up to 24 hours to cure without water and without stress, at an ambient temperature of 10 to 40 degrees Celsius.\u003c\/p\u003e\n\n\u003cp\u003eWe know from our inquiries that this specific point is the most frequently ignored—anyone who seals in the evening and gets in during the rain in the morning is testing a layer that isn't even finished yet.\u003c\/p\u003e\n\n\u003cp\u003eA detail that is increasingly relevant in everyday life in German-speaking countries: The St0.01 is designed for pump sprayers and sponges, not aerosols. Fine spray mist from a can is respirable, and especially those who regularly work in enclosed halls notice the difference. Always ventilate the interior well, regardless of the product.\u003c\/p\u003e\n\n\u003ch3\u003eWhat an interior sealant cannot do\u003c\/h3\u003e\n\u003cp\u003eA protective layer postpones wear; it does not eliminate it. These limits are clearly definable.\u003c\/p\u003e\n\n\u003cp\u003eIt does not help against UV-related hardening and shrinking. This requires deeply penetrating conditioning with antioxidants and UV absorbers—a sacrificial layer on the surface doesn't even reach the fiber underneath. Likewise, it does not protect against deep scratches from jean rivets, keys, or dog claws. Its flagship discipline is the fight against micro-abrasion and dye transfer—one should not expect more from it.\u003c\/p\u003e\n\n\u003cp\u003eProducts are certainly not interchangeable. We tested the waterproofing oil on densely coated new leather: It simply doesn't absorb; it lies on top as a film and binds dust. Conversely, a film-forming sealant has no business on Alcantara or open-pored aniline leather—it creates stains and dark edges that cannot be worked out.\u003c\/p\u003e\n\n\u003cp\u003eOn nubuck and suede, the same applies to the oil: It clogs the pile. If you are unsure about your material, test on a hidden area before treating an entire seat surface.\u003c\/p\u003e\n\n\u003cp\u003eThe most important distinction concerns repair. A sealant does not fix a color. Anyone who has tinted or repaired leather needs a genuine polyurethane clear coat with crosslinker as a finish, which binds the pigments and sets the gloss level—the professional way via \u003ca href=\"\/en\/collections\/koch-chemie-colourlock-faerben-top-coat\"\u003eTop Coat \u0026amp; Finish from COLOURLOCK\u003c\/a\u003e, applied with a spray gun. COLOURLOCK \"Leather Shield\" only goes on top afterwards, as a maintenance layer applied with a cloth. The other way around makes no sense: A Top Coat is not a product for the quarterly care routine.\u003c\/p\u003e\n\n\u003cp\u003eAnd one compromise compared to the rest of the market should be stated openly. Ceramic leather sealants based on SiO2 last significantly longer—sometimes up to twelve months—and are more chemically resistant. In return, they more frequently change the haptics: The leather becomes noticeably smoother, and a fine gloss often remains on matte OEM surfaces. The polymer approach of COLOURLOCK trades durability for original optics. If maximum durability is more important to you than the factory finish, a ceramic coating is the more honest recommendation.\u003c\/p\u003e\n\n\u003ch3\u003eWhich sealant your interior really needs\u003c\/h3\u003e\n\u003cp\u003eThe fastest way to a decision is through the material, not the vehicle age.\u003c\/p\u003e\n\n\u003cp\u003ePigmented smooth leather, young and in good condition, light-colored interior, or lots of jeans on board: COLOURLOCK \"Leather Shield,\" ideally right after delivery and with a few hours of rest to cure. The younger the finish, the more the abrasion protection contributes—on ten-year-old, dry leather, you get significantly more out of conditioning.\u003c\/p\u003e\n\n\u003cp\u003eIf the seat surface is faux leather, vinyl, or one of the vegan materials in modern electric cars, COLOURLOCK \"Artificial Leather Protector\" is the more suitable answer—technically closer to the substrate, especially for light-colored seats with a dye transfer problem. The most frequent question we receive regarding this category is exactly this distinction: Both protect against abrasion and color transfer, but each belongs on its own material.\u003c\/p\u003e\n\n\u003cp\u003eOpen-pored, natural, or heavily used smooth leather—classic car seats, saddlery, sturdy bags, outdoor shoes—get COLOURLOCK \"Care \u0026amp; Waterproofing Oil,\" sparingly and in several thin passes rather than one heavy application. Twice a year is a realistic interval for most applications.\u003c\/p\u003e\n\n\u003cp\u003eCloth seats, carpets, trunks, Alcantara, and fabric tops are covered by the Allround Textile Sealant \"St0.01.\" For family cars with sugary drinks in the back, for dog owners, and for convertible drivers, this is the area with the greatest noticeable everyday benefit—not because of the beading effect, but because stains can be removed from the surface afterwards instead of setting as a ring. You can find everything else from the brand one level up: \u003ca href=\"\/en\/collections\/koch-chemie-colourlock\"\u003eEverything from COLOURLOCK\u003c\/a\u003e.\u003c\/p\u003e\n\n\u003cp\u003eThe thought that carries the whole category is the same as with repair: COLOURLOCK has been earning its money since 1995 restoring damaged leather. The protective products exist so that it never gets to that point. A layer that costs a few minutes every few months determines whether the driver's seat needs to be recolored in five years or simply cleaned.\u003c\/p\u003e\n","products":[{"product_id":"koch-chemie-colourlock-allround-textile-sealant-st0-01-premium-textilversiegelung","title":"Allround Textile Sealant \"St0.01\" Premium Fabric Sealant","description":"\u003ch2\u003e\u003cstrong\u003eKoch-Chemie \u003cmeta charset=\"utf-8\"\u003e \u003cspan\u003e× COLOURLOCK\u003c\/span\u003e Allround Textile Sealant \"St0.01\" — Premium Fabric Sealant\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cp\u003eMeet the hard-working \u003cstrong\u003eKoch-Chemie × COLOURLOCK Allround Textile Sealant \"St0.01\"\u003c\/strong\u003e, the go-to answer for protecting and looking after the fabrics in your car.

Clean new or as-new leather first with a mild leather cleaner to pull off production residue, light body oils and micro-grime. You apply the product with a soft applicator in straight, overlapping passes until you get an even film. After a short flash-off, the leather dries to a silky matte; you don't need the usual buffing afterwards because the product leaves no wax-based residue. In detail areas especially — steering wheel, console leather, side bolsters — precise work pays off. Paired with regular mild cleaning, the protection holds steady. For high-mileage cars like company vehicles or daily drivers, a quarterly top-up makes sense, since these areas take more mechanical stress.\u003c\/p\u003e\n\u003ch3\u003eResults, durability \u0026amp; typical use cases\u003c\/h3\u003e\n\u003cp\u003eAfter you apply \u003cstrong\u003eLeather Shield\u003c\/strong\u003e, the leather's look stays factory-matte and free of the greasy shine that shows up fast on dark interiors. Durability naturally depends on use and material, since the product wears down mechanically as a protective layer. In everyday cars the benefits show strongest: even wear, less creasing and shine that turns up much later on side bolsters and steering wheels. For lease cars Leather Shield is almost a must, because it brakes visible ageing and keeps the interior feel solid right up to handover. It also holds up in professional detailing as part of a systematic leather-care process, since it's neither silicone-based nor over-conditioning and pairs perfectly with mild cleaners and later conditioner care.\u003c\/p\u003e\n\u003chr\u003e\n\u003ch2\u003eCommon questions about COLOURLOCK × Koch-Chemie Leather Shield\u003c\/h2\u003e\n\u003ch4\u003eCan I use Leather Shield on older leather too?\u003c\/h4\u003e\n\u003cp\u003eYes, but give older surfaces a thorough clean first and freshen them up lightly if needed.

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. The oil isn't meant for pigmented automotive leather or PU-coated surfaces — it would barely soak in there. On badly weathered leather, pairing it with intensive care, colour refresh or structural repair can be worth it. Its strength is clearly in the natural, non-coating way it repels water and the deep-down nourishment it delivers.\u003c\/p\u003e\n\u003chr\u003e\n\u003ch2\u003eCommon questions about COLOURLOCK Care \u0026amp; Waterproofing Oil\u003c\/h2\u003e\n\u003ch4\u003eDoes the oil darken the leather?\u003c\/h4\u003e\n\u003cp\u003eIt can darken very slightly, which is normal for open-pore leather.
