It is ideal for deep cracks, holes, breaks, edge damage, and material loss where conventional fillers are no longer sufficient. Targeted heat curing creates a particularly strong, dimensionally stable repair base that can then be sanded, textured, colored, and sealed.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeat-curing \u0026amp; highly stable\u003c\/strong\u003e – Ideal for structural repairs under high stress.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFor leather \u0026amp; plastic\u003c\/strong\u003e – Versatile for automotive and furniture applications.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePerfect repair base\u003c\/strong\u003e – Optimal for building up, shaping, and subsequent finishing.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003chr\u003e\n\u003ch3\u003eHeat-Curing Technology \u0026amp; Mechanism of Action\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eLeather \u0026amp; Plastic Paste\u003c\/strong\u003e is based on a special polymer formula that only fully hardens under heat. Controlled heating (e.g., with a heat gun) creates a particularly hard, resistant structure that can withstand strong mechanical stress. The paste shrinks very little, remains dimensionally stable, and is excellently suited for rebuilding edges, shapes, and missing material – both on leather and plastic surfaces.\u003c\/p\u003e\n\u003ch3\u003eApplication, Coverage \u0026amp; Best Practices\u003c\/h3\u003e\n\u003cp\u003eBefore application, the surface should be clean, dry, and free of grease. \u003cstrong\u003eCOLOURLOCK Leather \u0026amp; Plastic Paste\u003c\/strong\u003e is applied to the damaged area with a spatula or modeling tool and roughly shaped. The paste is then cured with controlled heat. After cooling, the repaired area can be sanded, smoothed, and further textured. Depending on the type of damage, the paste can be built up in layers. This is followed by color application and sealing with a top coat.\u003c\/p\u003e\n\u003ch3\u003eResults, Areas of Use \u0026amp; Demarcation\u003c\/h3\u003e\n\u003cp\u003eAfter curing, a very strong, durable repair area is created that is ideal for further processing. \u003cstrong\u003eLeather \u0026amp; Plastic Paste\u003c\/strong\u003e is suitable for car seats, door panels, center consoles, steering wheels, furniture, plastic trim, and interior parts. It is not a fine filler for small scratches but a structural repair paste for larger damages. For fine surface corrections, a classic filler or Super Filler is recommended afterwards.\u003c\/p\u003e\n\u003chr\u003e\n\u003ch2\u003eFrequently Asked Questions about COLOURLOCK Leather \u0026amp; Plastic Paste\u003c\/h2\u003e\n\u003ch4\u003eWhy is the paste heat-curing?\u003c\/h4\u003e\n\u003cp\u003eHeat ensures 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 is specially developed for leather and many plastics.\u003c\/p\u003e\n\u003ch4\u003eCan the paste be sanded?\u003c\/h4\u003e\n\u003cp\u003eYes, very well after full curing.\u003c\/p\u003e\n\u003ch4\u003eIs backing necessary?\u003c\/h4\u003e\n\u003cp\u003eFor holes or severe cracks, backing is recommended.\u003c\/p\u003e\n\u003ch4\u003eCan I dye it afterwards?\u003c\/h4\u003e\n\u003cp\u003eYes, after sanding, the surface can be dyed and sealed normally.\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":250.98,"currency_code":"EUR","in_stock":true},{"title":"20 ml","offer_id":56616788787535,"sku":"D1-KCX-594-20ML-01","price":103.45,"currency_code":"EUR","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.at\/en\/products\/koch-chemie-colourlock-leather-plastic-paste-waermehartende-spachtelmasse","provider":"Detailing1","version":"1.0","type":"link"}
