The work step between degreasing and dyeing: COLOURLOCK \"Leather Primer\" penetrates the top layer of pigmented smooth leather and bonds the prepared surface with the new dye. Developed for cars, furniture, and fashion, available in 250 ml and 1000 ml \/ 1 liter.\u003c\/em\u003e\u003c\/p\u003e\n\n\n\u003c\/blockquote\u003e\n\n\u003chr\u003e\n\n\u003cp id=\"speakable-definition\"\u003e\u003cstrong\u003eCOLOURLOCK Leather Primer\u003c\/strong\u003e is the primer used in leather restoration between the degreasing step and the first application of dye. COLOURLOCK \"Leather Primer\" penetrates the top layer of the leather or finish, balances out its varying absorbency, and provides a uniform, adhesive base for the subsequent leather dye. It is applied in a very thin layer, dries to a matte finish, and the layer remains elastic — because a seat bolster deforms every time you get in.\u003c\/p\u003e\n\n\u003cul\u003e\n\n  \u003cli\u003e\n\n\u003cstrong\u003eAdhesion begins before the first drop of dye.\u003c\/strong\u003e Used pigmented leather has an uneven surface: worn-down, open areas next to intact surfaces, with residues of old care products in between. The primer lays a uniform layer over this patchwork, allowing the dye to bond evenly everywhere — not just where the leather was already absorbent.\u003c\/li\u003e\n\n  \u003cli\u003e\n\n\u003cstrong\u003eA uniform base saves on dye applications.\u003c\/strong\u003e On unprimed leather, open areas soak up the first application of dye, while closed areas leave it sitting on top, forcing you to use additional coats to counteract this difference. On a primed surface, the first layer provides even coverage. Practical: fewer coats, less layer thickness, softer feel.\u003c\/li\u003e\n\n  \u003cli\u003e\n\n\u003cstrong\u003eTwo containers for two project sizes.\u003c\/strong\u003e 250 ml covers a steering wheel rim, a seat bolster, and individual repair areas; 1000 ml \/ 1 liter is for the complete set and ongoing use in detailing shops and upholstery businesses. Because the primer is misted on rather than flooded, even the smaller container will last through several projects.\u003c\/li\u003e\n\n\n\u003c\/ul\u003e\n\n\u003chr\u003e\n\n\u003cblockquote class=\"praxistipp\"\u003e\n\n  \u003cp\u003e\u003cstrong\u003ePractical tip from Detailing1:\u003c\/strong\u003e The most common mistake when priming is using too much product. We frequently receive photos of seat bolsters where the fresh dye starts peeling off in flakes after a few weeks, and almost always the primer was applied heavily instead of being lightly misted. A thick primer layer dries as a film of its own, which detaches from the leather the first time the bolster is deformed, taking the dye with it. Therefore, test it on a hidden spot roughly the size of a palm: the primer must dry to a dull, matte finish. If the spot is glossy or feels smooth, too much was applied — in that case, degrease it and apply a thinner coat before the dye.\u003c\/p\u003e\n\n\n\u003c\/blockquote\u003e\n\n\u003chr\u003e\n\n\u003ch3\u003eFlaking leather dye is almost always an adhesion problem\u003c\/h3\u003e\n\u003cp\u003eLeather dye rarely fails across the entire surface. It comes off where the leather is subject to stress: on the seat bolster, the steering wheel rim, the entry edge, and furniture edges.\u003c\/p\u003e\n\n\u003cp\u003eThe reason lies beneath the dye. Used pigmented leather no longer has a uniform surface, but rather a mosaic of three conditions: areas where the old dye and protective layer are still intact, areas where it is worn through and the open fiber is exposed, and areas where care products have left silicones and fats behind. New dye encounters different conditions on all three. On the closed layer, it barely finds a grip; in the open fiber, it sinks in; on the care product film, it merely sits on top.\u003c\/p\u003e\n\n\u003cp\u003eWhat we at Detailing1 read in inquiries about failed dyeing jobs again and again sounds almost verbatim: On the first day, the seat looked like new; after a few weeks, it began to flake at the bolster; and during cleaning, the dye came off in streaks. That is not a dye defect. That is a dye layer that never had a common foundation.\u003c\/p\u003e\n\n\u003cp\u003eThis is exactly the foundation that the primer creates. It levels the three conditions into a single one: a continuous, uniformly absorbent surface where the dye forms the same bond everywhere. The difference shows not on the day of dyeing, but after the first half-year of daily use — that is when the contact zones have undergone their first few thousand movements.\u003c\/p\u003e\n\n\u003ch3\u003eAdhesion is decided in the layer beneath the dye\u003c\/h3\u003e\n\u003cp\u003eCOLOURLOCK \"Leather Primer\" works with binding agents, i.e., film-forming polymers that, when drying, form a cohesive net over the leather surface and remain anchored within it.\u003c\/p\u003e\n\n\u003cp\u003eThis net reaches down into the leather surface and offers an open, absorbent side upward. Imagine it like the primer before painting: an intermediate layer that matches both sides, even though the two materials struggle to bond on their own. For you, this means: the dye does not end up sitting on the leather; it sits in a layer that is itself anchored into the leather.\u003c\/p\u003e\n\n\u003cp\u003eThe second active factor is elasticity. A seat bolster deforms every time you get in, a steering wheel rim in every turn, a furniture edge with every forearm. A hard primer would not withstand this movement and would form fine cracks through which the structure above would break. The primer remains soft and stretchy. You can tell: the dyed leather feels like leather afterward, not like painted plastic.\u003c\/p\u003e\n\n\u003cp\u003eAdded to this is an effect that is most noticeable in everyday life. Because the primed surface absorbs evenly everywhere, even the first coat of dye provides uniform coverage instead of sinking into the open zones. This saves on applications, and every saved application means less layer thickness on the leather. Thin structures withstand movement better than thick ones — which is why the primer is not just an issue of adhesion, but also of feel and durability.\u003c\/p\u003e\n\n\u003cp\u003eA detail from repair practice explains why this is followed so consistently: COLOURLOCK was founded in 1995 at the Lederzentrum and has been supplying upholsterers and detailers for three decades who provide warranties for their dye jobs. Anyone who has to avoid rework does not skip an intermediate step. Since the acquisition by Koch-Chemie, the line has been running in our shop under Koch-Chemie × COLOURLOCK; nothing has changed in the system logic.\u003c\/p\u003e\n\n\u003ch3\u003eThe primer goes on after degreasing and before the dye\u003c\/h3\u003e\n\u003cp\u003eThe sequence of a leather dyeing job is defined by the data sheet and is non-negotiable: clean, degrease, prime, fill, dye, finish with Top Coat.\u003c\/p\u003e\n\n\u003cp\u003eBefore the primer comes degreasing. Skin oils, sunscreen, and care product residues form a barrier that even the best primer cannot penetrate — the \u003ca href=\"\/it\/collections\/koch-chemie-colourlock-reinigung-entfetter\"\u003edegreaser\u003c\/a\u003e removes them without solvents and leaves a matte surface. Only then is COLOURLOCK \"Leather Primer\" applied. The surface must be completely dry, as residual moisture has the same effect as grease: it keeps the primer away from the leather.\u003c\/p\u003e\n\n\u003cp\u003eAfter priming, the structure is built up if the leather is damaged. Cracks and open areas are closed and smoothed with filler, then the \u003ca href=\"\/it\/collections\/koch-chemie-colourlock-faerben-lederfarben\"\u003eleather dyes\u003c\/a\u003e are applied in several thin coats. The process is concluded with the \u003ca href=\"\/it\/collections\/koch-chemie-colourlock-faerben-top-coat\"\u003eTop Coat\u003c\/a\u003e, the clear coat of the leather industry: it seals the dye against abrasion and determines the gloss level. The finish is adjusted via \u003ca href=\"\/it\/collections\/koch-chemie-colourlock-faerben-additive\"\u003eadditives\u003c\/a\u003e, from matting agents to feel additives for velvety or waxy surfaces.\u003c\/p\u003e\n\n\u003cp\u003eEach of these layers relies on the one below it holding fast. This is the real reason why the primer carries so much weight: it is the only layer that has direct contact with the leather. If the chain breaks here, it breaks across the entire surface — regardless of how cleanly the dye and Top Coat were applied.\u003c\/p\u003e\n\n\u003cp\u003eThis system logic is professional chemistry, not a hardware store spray set. It also provides the advantage that every step can be checked individually. After degreasing, you can see if the surface is matte. After priming, you can see if it has dried to a uniform, dull finish. Anyone who takes these two control points seriously has completed the invisible part of the project before the first dye comes into play.\u003c\/p\u003e\n\n\u003ch3\u003eToo much primer weakens adhesion\u003c\/h3\u003e\n\u003cp\u003eThe application is explained in one sentence: mist thinly and evenly, do not flood, and let dry until the surface is dull-matte.\u003c\/p\u003e\n\n\u003cp\u003eIt is preferable to work with a spray device because it delivers the finest and most uniform distribution. For smaller surfaces, a sponge, brush, or lint-free cloth is sufficient. The dosage depends on the leather: a highly pigmented, still closed surface needs only a touch, while more open-worn zones on the seat bolster and entry edge absorb more, and a second thin pass is sensible there. Rough edges on dried-out cracks are smoothed beforehand with a fine sanding pad; otherwise, every fiber edge will show through the dye later.\u003c\/p\u003e\n\n\u003cp\u003eIn terms of time, this is the smallest step in the entire project. In the Detailing1 everyday life: a steering wheel is primed in about a quarter of an hour including drying, a single seat in about half an hour, a complete set in a morning. Measured against the hours that dye buildup and Top Coat take afterward, this is the smallest time expenditure with the greatest leverage.\u003c\/p\u003e\n\n\u003cp\u003eTwo conditions influence the outcome. On sun-heated seats, the primer sets before it has distributed itself and leaves clouds — it is better to work in the shade or with the door open. And drying takes its minutes: as long as the surface is still sticky or glossy, it is not ready for dye. The check is simple: check with the back of your hand instead of your fingertip, because finger oil brings back exactly what you just removed.\u003c\/p\u003e\n\n\u003ch3\u003eAniline leather and plastic parts need different primers\u003c\/h3\u003e\n\u003cp\u003eThe most important limit is stated on the data sheet: COLOURLOCK \"Leather Primer\" is developed for pigmented smooth leather, not for open-pored leather.\u003c\/p\u003e\n\n\u003cp\u003eAniline leather and nubuck have no closed top layer. Their open pores soak up any liquid unevenly, and instead of a uniform adhesive base, you get dark edges and stains. We replicated this on an open-pored sample piece: the primer disappears completely into the fiber in one place, is still on the surface three centimeters further on, and the edge between both zones remains visible afterward. For these types of leather, the path leads via its own, leather-type-specific preparation.\u003c\/p\u003e\n\n\u003cp\u003eThe second limit is the material. Modern interiors combine leather with plastic carriers, trim, and synthetic leather parts. The binding agents of the leather primer do not reliably grip these surfaces; that is the task of the \u003ca href=\"\/it\/collections\/koch-chemie-colourlock-faerben-kunststoff-grundierung\"\u003eplastic primer\u003c\/a\u003e. Similarly, the primer is not intended for migrating discolorations: if dyes from dark clothing or the substrate migrate into the new layer, that is the job of the \u003ca href=\"\/it\/collections\/koch-chemie-colourlock-faerben-sperrschicht\"\u003ebarrier coat\u003c\/a\u003e, not the primer.\u003c\/p\u003e\n\n\u003cp\u003eThree further points should be mentioned honestly. The primer replaces neither cleaning nor degreasing; it assumes both. It is not a product in itself, but exclusively preparation — without subsequent dye, a primed surface has no use and no protection. And it does not improve a color tone: whether the new dye matches the remaining original tone is decided by the dye and its adjustment, not by the primer. Always count on a deviation with old leather, because years of UV light have shifted the original tone.\u003c\/p\u003e\n\n\u003cp\u003eAnd one limit that is not chemical: seats with side airbags have defined tear seams that must tear open perfectly in an emergency. Dye and primer application must not stiffen or glue these seams. If your vehicle has an airbag installed there, the surface belongs in the hands of an upholsterer who will treat the seam professionally — this is not a cautionary formula, but the point at which a home project sensibly ends.\u003c\/p\u003e\n\n\u003ch3\u003eWhich container fits your dyeing project\u003c\/h3\u003e\n\u003cp\u003eThe choice depends solely on the surface area you want to prime, because both containers contain the same product in different quantities.\u003c\/p\u003e\n\n\u003cp\u003e250 ml is enough for a steering wheel, a seat bolster, a gear shift gaiter, or a single furniture edge — i.e., for the typical case where a worn spot is being dyed again. Anyone restoring a complete set of seats or a sofa, or anyone who dyes regularly, should go for the 1000 ml \/ 1 liter: this is the format in which detailing shops and upholsterers work, and it also covers several vehicles. Both sizes are the same \u003ca href=\"\/it\/products\/koch-chemie-colourlock-leather-primer-haftvermittler-leder\"\u003eCOLOURLOCK \"Leather Primer\"\u003c\/a\u003e; the formula does not change with the bottle size.\u003c\/p\u003e\n\n\u003cp\u003eIf you are dyeing for the first time, plan the primer firmly into the process instead of treating it as an optional extra step. The inquiries about flaking dye jobs we receive come almost exclusively from projects where this very step was skipped. The rest of the range for preparation is on a higher level: \u003ca href=\"\/it\/collections\/koch-chemie-colourlock-faerben-leder-grundierung\"\u003eBack to Leather Primer from COLOURLOCK\u003c\/a\u003e.\u003c\/p\u003e\n\n\u003cp\u003eAnd the thought that carries the whole category: the primer is the shortest work step in the entire dyeing project and the only one you cannot retrofit later. Dye can be added, Top Coat can be renewed, a feel additive can be dosed differently next time. A missing primer lies beneath everything — you only reach it by taking the entire buildup back off.\u003c\/p\u003e\n","products":[{"product_id":"koch-chemie-colourlock-leather-primer-haftvermittler-leder","title":"COLOURLOCK \"Leather Primer\" promotore di adesione per fondo e colore della pelle","description":"\u003ch2\u003eCOLOURLOCK Leather Primer — promotore di adesione per una vera presa del colore sulla pelle\u003c\/h2\u003e\n\u003cblockquote\u003e\n\u003cp\u003e\u003cem\u003eA cosa serve il COLOURLOCK Leather Primer? — Il primer crea una superficie che fa presa in modo uniforme, stabilizza la struttura della pelle e migliora nettamente il modo in cui prodotti di colore e riparazione come Leather Fresh o Fluid Leather si legano ad essa.\u003c\/em\u003e\u003c\/p\u003e\n\u003c\/blockquote\u003e\n\u003chr\u003e\n\u003cp\u003e\u003cstrong\u003eCOLOURLOCK Leather Primer\u003c\/strong\u003e è il promotore di adesione professionale per ogni riparazione della pelle in cui un ravvivamento del colore, una ritintura o una ricostruzione della struttura deve tenere nel tempo.
