It is ideal for scratches, cracks, scuffs, edge chips or deep abrasions and forms a stable, finely sandable surface after drying. The white color ensures that repairs on white or very light leathers can be built up particularly cleanly and color-neutrally — perfect for automotive interiors, furniture, bags, sneakers and accessories.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eIdeal for light leathers\u003c\/strong\u003e – White filler enables color-neutral, invisible repair builds.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinely sandable \u0026amp; stable\u003c\/strong\u003e – For smooth, durable and even surfaces.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOptimal adhesion\u003c\/strong\u003e – Perfect as a base for color, binder and top coat.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003chr\u003e\n\u003ch3\u003eFiller Technology \u0026amp; Mechanism of Action\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eFiller (White)\u003c\/strong\u003e is based on an elastic, dimensionally stable filler formula that bonds deeply with the leather and forms a robust repair layer. After application, the material hardens into a firm yet flexible structure that can be sanded and worked on excellently. This allows indentations to be precisely leveled and damaged areas to be cleanly modeled. The white pigmentation prevents dark backgrounds from showing through and facilitates an even application of color on light materials.\u003c\/p\u003e\n\u003ch3\u003eApplication, Coverage \u0026amp; Best Practices\u003c\/h3\u003e\n\u003cp\u003eBefore filling, the leather should be thoroughly cleaned and degreased. \u003cstrong\u003eFiller (White)\u003c\/strong\u003e is applied thinly with a spatula, scalpel, brush or fine applicator tip. For deep damage, a layer-by-layer application is recommended, with a drying and sanding phase between each layer. Once the surface is smooth and even, it is color-matched with leather dye or Leather Fresh and finally sealed with Top Coat. The filler can also be thickened with Thickener if more stability is desired.\u003c\/p\u003e\n\u003ch3\u003eResults, Areas of Application \u0026amp; Benefits\u003c\/h3\u003e\n\u003cp\u003eAfter treatment, the repaired surface appears smooth, homogeneous and color-neutral — an ideal basis for perfect finishing results. \u003cstrong\u003eFiller (White)\u003c\/strong\u003e is suitable for white car seats, steering wheels, furniture, sneaker leather, boots, bags and light interior parts. It does not replace back-bonding for deep cracks, but forms the optimal structure for all visible surface corrections on light leathers.\u003c\/p\u003e\n\u003chr\u003e\n\u003ch2\u003eFrequently Asked Questions about COLOURLOCK Filler (White)\u003c\/h2\u003e\n\u003ch4\u003eWhy a white filler?\u003c\/h4\u003e\n\u003cp\u003eIt prevents dark areas from showing through and enables color-neutral repairs on light leather.\u003c\/p\u003e\n\u003ch4\u003eCan the filler be sanded?\u003c\/h4\u003e\n\u003cp\u003eYes, after drying it can be sanded and smoothed very well.\u003c\/p\u003e\n\u003ch4\u003eIs Filler (White) flexible?\u003c\/h4\u003e\n\u003cp\u003eYes, it remains flexible enough for typical leather movements.\u003c\/p\u003e\n\u003ch4\u003eDo I need color afterwards?\u003c\/h4\u003e\n\u003cp\u003eYes, the filler forms the base — then leather dye or Leather Fresh follows.\u003c\/p\u003e\n\u003ch4\u003eIs the filler suitable for artificial leather?\u003c\/h4\u003e\n\u003cp\u003eYes, it is very suitable for many types of artificial leather.\u003c\/p\u003e\n\u003chr\u003e\n\u003cp\u003e\u003csmall\u003eLast updated: 10.12.2025 — Author: Daniel (Detailing1)\u003c\/small\u003e\u003c\/p\u003e","brand":"Koch-Chemie × COLOURLOCK","offers":[{"title":"1000ml \/ 1 liter \/ White","offer_id":56584511881551,"sku":"D1-KCX-608-1L-01","price":268.0,"currency_code":"USD","in_stock":true},{"title":"20 ml \/ White","offer_id":56584504213839,"sku":"D1-KCX-608-20ML-01","price":66.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/3272\/7375\/files\/608-20ML-01_1.png?v=1765306083","url":"https:\/\/detailing1depot.com\/en\/products\/koch-chemie-colourlock-filler-white-leder-fuellstoff","provider":"Detailing1","version":"1.0","type":"link"}
