It's the one you grab for deep cracks, holes, breaks, chipped edges and missing material, where an ordinary filler just won't cut it anymore. Cure it with heat and you get a rock-solid, dimensionally stable base that you can then sand, texture, colour and seal.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeat-curing \u0026amp; high-strength\u003c\/strong\u003e – built for structural repairs that take real load.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFor leather \u0026amp; plastic\u003c\/strong\u003e – works across automotive and furniture jobs.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eA proper repair base\u003c\/strong\u003e – ideal for building up, shaping and finishing afterwards.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003chr\u003e\n\u003ch3\u003eHeat-curing technology \u0026amp; how it works\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eLeather \u0026amp; Plastic Paste\u003c\/strong\u003e is built on a special polymer formula that only cures fully once you apply heat. Warm it up in a controlled way (a heat gun does the job) and it sets into a hard, tough structure that shrugs off heavy mechanical load. The paste barely shrinks, holds its shape and is brilliant for rebuilding edges, contours and missing material — on leather and on plastic alike.\u003c\/p\u003e\n\u003ch3\u003eHow to apply it \u0026amp; best practices\u003c\/h3\u003e\n\u003cp\u003eBefore you start, the surface needs to be clean, dry and grease-free. Work \u003cstrong\u003eCOLOURLOCK Leather \u0026amp; Plastic Paste\u003c\/strong\u003e into the damaged spot with a spatula or modelling tool and rough it into shape. Then cure the paste with heat, keeping it controlled. Once it's cooled, you can sand, smooth and texture the repair. Depending on the damage, you can build the paste up in layers. After that comes the colour build-up and the seal with Top Coat.\u003c\/p\u003e\n\u003ch3\u003eResults, where it fits \u0026amp; where it doesn't\u003c\/h3\u003e\n\u003cp\u003eOnce cured, you're left with a very solid, hard-wearing repair that takes further work beautifully. \u003cstrong\u003eLeather \u0026amp; Plastic Paste\u003c\/strong\u003e is right at home on car seats, door cards, centre consoles, steering wheels, furniture, plastic trim and interior parts. It's not a fine filler for light scratches — it's a structural repair paste for bigger damage. For fine surface touch-ups afterwards, reach for a classic filler or Super Filler.\u003c\/p\u003e\n\u003chr\u003e\n\u003ch2\u003eCommon questions about COLOURLOCK Leather \u0026amp; Plastic Paste\u003c\/h2\u003e\n\u003ch4\u003eWhy is the paste heat-curing?\u003c\/h4\u003e\n\u003cp\u003eThe heat gives you maximum strength and dimensional stability for structural repairs.\u003c\/p\u003e\n\u003ch4\u003eCan I use the paste on plastic?\u003c\/h4\u003e\n\u003cp\u003eYes, it's made specifically for leather and many plastics.\u003c\/p\u003e\n\u003ch4\u003eCan the paste be sanded?\u003c\/h4\u003e\n\u003cp\u003eYes, very well once it's fully cured.\u003c\/p\u003e\n\u003ch4\u003eDo I need a backing patch?\u003c\/h4\u003e\n\u003cp\u003eFor holes or bad cracks, a backing patch is recommended.\u003c\/p\u003e\n\u003ch4\u003eCan I colour it afterwards?\u003c\/h4\u003e\n\u003cp\u003eYes, after sanding you can colour and seal the area as normal.\u003c\/p\u003e\n\u003chr\u003e\n\u003cp\u003e\u003csmall\u003eLast updated: 12\/12\/2025 — Author: Daniel (Detailing1)\u003c\/small\u003e\u003c\/p\u003e","brand":"Koch-Chemie × COLOURLOCK","offers":[{"title":"1000ml \/ 1 liter","offer_id":56616788820303,"sku":"D1-KCX-594-1L-01","price":1188.59,"currency_code":"PLN","in_stock":true},{"title":"20 ml","offer_id":56616788787535,"sku":"D1-KCX-594-20ML-01","price":493.25,"currency_code":"PLN","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/3272\/7375\/files\/594-20ML-01_1.png?v=1767911713","url":"https:\/\/detailing1.pl\/en\/products\/koch-chemie-colourlock-leather-plastic-paste-waermehartende-spachtelmasse","provider":"Detailing1","version":"1.0","type":"link"}
